are the injectors u/s??
having eventually got the car to a stage near completion, i've wired up my injectors as per the megasquirt diagram, i'm fairly sure
i've got it right as i get a power pulse when i turn on the ignition and cranking power at the injector when turning over, however i'm not
getting any fuel delivered thru the injectors although i have got fuel pressure in the fuel rail, anyone got any ideas that i may not have thought of?
spec is: 2.0 redtop engine
gsxr TB's
cream vauxhall injectors
MS1 extra ecu
hp fuel pump
adjustable fuel reg

Check that you have the fuel flow and return on the correct ends of the fuel rail.
I've made the mistake of putting the flow on the pressure regulator before and you get no fuel at the injectors!

If they have been stored for a while they can get gummed up. If you put a screwdriver to each of them and your ear at the opposite end you should hear
them clicking.
If they are sticking they may free up if you exercise them by applying voltage on and off to them.
Otherwise may need cleaning see link

When I first started my engine after 18 months out of the donor, one cylinder was not getting any fuel, I swapped the injectors around to check and
one was blocked. A soak in carb cleaner over night sorted the problem.
A good check to see if they are working is to listen, you should hear clicking on tickover or crank like 'hollywood crickets'
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

don't know how good they were before i got them, so they could be gummed up i'll try the listening thing

Do not forget that the system switches earths so one side should have a full battery.
I cleaned mine by running paint thinners through them, used a 12v mains transformer with one diode as a rectifier so get 50hz pulsed battery then just
stuck the fuel pump in circuit squirting into a jam jar so i could see the spray pattern.
I few minutes sorted them all out.
