had a go at trying to start it for the first time today but had no joy.
ignition on and the fuel pump primes all ok. cranking it i get a spark but it wont go.
doesn't seem to have any pressure in the fuel rail, i remove the inlet pipe and get a tiny drop of fuel, not even enough to dribble out.
put the fuel pipe into a jar and when the pump primes it sends quite a bit of fuel out so the pump seems ok.
time was getting on and the battery was getting low so i never got round to checking fuel comes out when its cranking.
i'm thinking that just the pump priming should give me noticeable pressure in the fuel rail?
will try blocking the fuel return tomorrow and see what happens.
anyone any other ideas?
thanks
its using the bikes fuel pump

Sorry if its something you've checked, is the flow and return connected the right way on to the fuel rails, regulator etc?, Its an easy mistake, one I and others have made with our subaru set-ups.
yes, they are the right way. flow is through the original clip on fitting, return comes from the regulator
had exactly the same prob last week when starting my 5pw r1 i am running a standard r1 pump in tank pump sounded fine but delivered very little fuel same as yours i think it must of been air locked removed pump checked-all ok refitted pump and filled tank with fuel,primed pump few times with lines disconnected and had really good output,refitted fuel lines and she started first flick of the key...its a great milestone!!!! good luck hope this helps
mine seems to be pumping quite a bit of fuel through when its priming with the supply line disconnected though.
will bear it in mind though
Fit an inline fuel pressure gauge, did it to mine to ensure the 3 bar reached. You have got the pump fitted in the bottom of the tank haven't you? They point up from the mounting flange
yes, pump is fitted from the bottom.
got a couple of hours spare before the football tomorrow, if i don't get any where with it then will try and borrow a pressure gauge to test the
pump.
Had an issue when it just wouldn't start, advice from a fellow racer with r1 expirience was to try and start it with throttle wide open, hey
presto it fired up within a few cranks. Its only ever done it once since.
ha
You defo have plug loom in correct order, not back to front, standard loom brings wiring to the front of the car. i put mine on back to front the first time
yes correct order, had to modify it slightly to get the connecter to the back of the engine as like you say as standard its at the front.
definatly thinking it has to be fuel as after a lot of cranking the plugs where bone dry and no smell of fuel
fuel pressure problem is sorted.
for reference any problems with fuel pressure using the r1 pump there is an o-ring in the fuel pump. when i seated it correctly i got pressure when
the pump primed. straight away i could here the air from the fuel system gurgling back into the tank.
the pump assembly comes apart by releasing 4 large tabs. the outlet pipe on the bottom section goes up into a tube on the top pump section, when
disassembling the o-ring stays in the top section.
reseat the o-ring in the recess on the bottom section pipe and then push the white plastic bit into the o-ring then reassemble the whole lot.
quick test i found when the o-ring wasn't seated right fuel would run out of the supply pipe, thats how i drained the tank. when it was seated
correctly no fuel came out.
still haven't got it running, it has fuel as the plugs where damp and it dribbled a bit out of the exhaust ports. it also has spark on all 4
plugs.
it cranks and pops occasionally with a little smoke from the exhaust ports and a couple of times it started to pick up a little for a second.
by then the battery was about flat so its gone back on charge.
Sounds like your nearly there, don't forget we need a first start video or it didn't happen!
Take care
Rich
got a video, not of it starting though.
just had another quick try with no joy. not even tying to pick up this time, just a few pops now and again. you can here them in this vid
http://s171.photobucket.com/albums/u310/bigfoot4616/striker/?action=view¤t=VIDEO0001.mp4
one problem is the battery doesn't last long and the optimate takes ages to recharge it.
i take it that as i have fuel and spark electrics wise it should start? i do have a few spare wires that aren't mentioned in the wiring
diagrams.
thanks
Hi
Have you spun it up with out the plugs in? It you say that fuel is in the cylinders and on the plugs, it doesn't take much to flood these engines
and from your vid it sounds like it's firing in the exhaust which indicted fuel mixture issue. Have you tried new plugs?
Sounds simple but a lot of time it is the simple things that catch us out
Is there any other work you've done on the engine?
Cheers
Rog
spun it over without plugs and no fuel before trying to start it for the first time.
was planning on picking up some new plugs to try.
not done any other work to the engine.
thanks
Ya, I would defo start with new plugs. Once they have been flooded and dried they can track and flood easy. Hope they work.
Try putting the plugs in hot, use a blow torch it helps keep them clean.
Have you checked the spark at all 4 coils/plugs? 5vy won't start with one spark missing.
rotax78 on here had no no3 spark on his. Ruled out coils and plugs by swapping them around but the none spark stayed in the same place and the loom
tested OK. Put my ecu on his car and it fired first time. Tried his ECU on mine and it wouldn't start.
Have you checked all your connectors 10
times. I had the very same problem. Took my loom appart. Got steve Hignett over. Nothing then we noticed I had plugged a dark grey connector in to a
black one. They are both the same just coloured different. I was gutted. But fired up straight away. Numpty me.
Your closer to starting than me though

Tilt swich the right way? "UP" should be on the top, not the side the right way up like writing on a packing box. If you siliconed it, be
sure it stuck it in the right place (mine didn't)
When you re-wired the coil loom did you do the same with the injectors? Fueling is sequential.
Those are a bit clutching at straws...
Someone on here did have a wire terminal push itself out of it's connector block and prevent starting so worth going through them all.
Are all earths connected (PowerCommander included)?
[Edited on 9/1/12 by adithorp]
sounds simalar as mine i had incorrect firing order 
try swapping coils about!!
Back to those plugs I think there were 5 wires in each and maybe one was a different colour on each plug. But keep checking. I hate wiring
tilt switch is as you say, not glued up yet. wouldn't that stop either fuel or spark or both?
coil loom is as it came apart from the wires to one coil where lengthened. injector wiring is also as it came apart from being shortened just before
the plug to the throttle bodies.
not even plugged the power commander in yet

you'll have quite a bit to do on yours won't you
New plugs.....
Phil
went to get some new plugs today, they didn't have any so will try and get some tomorrow.
phoned up malc today as he supplied everything and he suggested some fuel in the throttle bodies to see if it would spit back through them, if so coil
wires would need swapping round.
made no difference.
had a good look over the wiring and noticed that on the multi plug that connects the coils to the main loom the coil trigger wires didn't match
up with the same colours either side of the plug. i then swapped the coil connecters round so they where correct with the ecu side of the loom, ended
up swapping 1 and 4, 2 and 3.
still didn't start but this time it was puffing balls of flame out of the exhaust ports.
with tonight's previous attempts to start it there was quite a bit of petrol about which had got soaked into a rag i had left on the floor,
when it first flamed it ended up with me having to stamp on the rag a few times to put it out 
another call to malc tomorrow i think
new plugs are coming friday, no one local has any in stock.
put the coil wires back to there original location. then i gave the plugs a blast with a blow lamp and it nearly started, if i hadn't stupidly
let go of the start button i think it may even of started. needed to get back to work so left it at that. will try again tomorrow
any news fella
still not running. not really any better with new plugs although it now will nearly start with a little fuel poured down the throttle bodies but not
when the injectors are squirting.
spoke to andy bates today about something else so i asked him, he thought that everything sensor /switch wise must be correct as its trying to go with
fuel and spark. i mentioned it was a white spark and he reckoned it should be a "fat blue" spark and possibly a weak spark could be stopping
it starting. suggested checking it had good engine earth.
it was very cold in the garage at the weekend which wont have helped, also meant i didn't spend much time in there
I'm not the best with electricity but if you need an extra pair of hands I will pop up if your desperater
If you are in doubt about the wiring and its not hard wired to the car yet, If you want to send the loom etc up to me I will get the lecky part of it
checked against the cars that I have here an get it runnining on mine.
No doubt you are getting severly pee'd off by now!
(done 3 5vys & got 2 cars here)
What is your set up at the mo ECU & loom, uk or states?
cheers D

Have you connected up the throttle cable? Looking at the video it looks like there isn't one.
Maybe your engine can start without a timely blip, but on occasions I have found it useful to blip the throttle (either the help the engine spin a bit
faster, or to clear a bit of a flood). You might also want to connect a substantial (maybe car) battery as those little bike ones are a bit rubbish
(especially when cold).
no throttle cable connected, i have been playing around with the throttle direct on the throttle bodies but it doesn't make any difference.
lack of 3 hands meant i couldn't do it while videoing
to get it to where it nearly starts on fuel dribbled direct into the throttle bodies i also have to open up the throttle.
soon gave up with the bike battery and am using a good car battery at the moment
No worries, these engines will start up no problem if the set up is right without fannying about with throttle cables etc!
Offer is there if I can help.
cheers

it runs
malc had sent me various things to swop over and try including another ecu. nothing made any difference apart from the start cut of relay when it was
much closer to starting. from the diagram i can't see how that can of been causing the problem though.
back in the garage today managed to get it to start by disconnecting the linkage to the secondary butterflies and manually opening them and holding
the throttle wide open when cranking, after about 20 seconds it fired up and idled ok.
no exhaust so i only ran it for 30 seconds. 20 minutes later tried it again and it started on the button with no throttle.
hoping it gets a bit warmer next week so i can get cracking on the rest of the jobs that need doing.
thanks
Nice one. You can come wire mine up now lol
Nice one.

Slowly. Sorted fuel tank out. Sent my engine to AB. My gear box is knackered
So gone even slower
