Just converted my striker from 16v to 20v and I cannot get it to start

I have a spark and fuel, all it does is turn over but not even a splutter nothing it just turns over like no leads are connected and does not catch.

any ideas?

Check all the basics, too much to think about there...

Incorrect timing??

Leads on the wrong plugs??

As above might be the timing but you would expect to hear a bang or pop in the process. How strong is the spark when you check it? Can you smell fuel after trying to turn it over?

is the ecu correct for the engine ?? you mention changing the engine but not ecu

The car is running an omex 600 ecu, I have just installed the raw map and it is the wasted spark version so I do have a good spark at the plugs? Also I can look down the throttle body and see the fuel being injected in.

Suggests you have no spark at all. Have you tried a plug out of the engine against the block to look for a spark yourself??

Yeah removed plugs 1 and 3 and can see the spark? its still dead

don't know the Omex stuff that well, does it tell you if you're getting any data from the crank position sensor?

Have you got a timing light to check that it is firing the right cylinder at the right time?

Try some ez-start down the inlet manifold - if it fires, then the map prob isn't supplying enough fuel - an engine will start when it's rich but not when it's too lean - ez-start is a good way of checking for this....

Check it's firing on no.1 plug with no.1 piston at/near TDC with all no.1 valves closed as a first approximation to timing - it should at least fire if you have this & the other plug leads on right....

Thanks all, will try suggestions and get back to you

Hi Can anyone confirm the wire colours from the omex loom to the idle valve. I have the raw diagram but the omex manual uses another wire?

its alive had a crossed wire on the ignition module changed this then it kicked into life.
