R32 Gtr Won't Start

[phat25t]

Car has been off the road for months now and still can't get it started. Car cranks but doesn't fire. I've tried changing the crank angle sensor and the ecu with no improvement. I definitely have spark but no injector pulse. I can't get an auto sparky who is mobile and able to check it out so any help would be greatly appreciated if someone could help me diagnose the problem.

Cheers,

Steve

Bridge the connectors on the consult port and see what error code/s it gives (if any), let us know.

I wouldnt have a clue how to do that mate, is it simple?

Ok I have checked for fault codes, only came back with 55 which from what I can gather means 'no malfunction' so I have no idea where to go from here. I have also checked the resistor which is fine, cas is definitely fine and I do have injector pulse its just too weak to show up with a noid light. Anyone got any ideas?

How good is the battery? (And just because it cranks the engine doesn't mean the engine will fire. ECU needs about 7 V to "stay alive").

Is the CAS in the correct position? It should align on a half-moon key in the end of the exhaust cam. If the key is broken, then the CAS can align anywhere.

Can you hear the injectors pulsing while engine is cranking? (Use a screwdriver as a stethoscope)

The battery is brand new, auto sparky checked it thats definitely fine. The cas alignment key is fine thats been checked I'm going to pull the rail out and make sure they are doing what hey should be doing tomorrow.

did you change larger injectors? it you changed it, you might want to change the setting your ecu

No injectors are stock

Check the coli-packs and spark plugs i hav the same problem also fule pumb as well

Ok, have you got spark happening? Have you got fuel coming out of injectors?

I have got around to pulling the fuel rail out, there's minimal to no fuel coming out of the injectors, I definitely have fuel pressure though and I definitely have spark. I have weak injector pulse (barely lights up a noid light). So I am guessing it has something to do with that. Any ideas what this could be, I've already tested the ecu and cas they are both fine. And I have done a diagnostic and come back with code 55-'no malfunction'.

Have you got the hoses on the right way?

Try this: switch ign to ON (to prime the pump and injector rail), then apply direct power to one side of the injector, other side of injector to earth. This should open the injector. Does fuel squirt out?

I'm heading away on holiday but ive got an auto sparky coming around in 2 weeks when im back so I'll get him to do this and ill let u know incase I don't get it sorted. I compared the injector pulse with my mates r32 gtr and his lghts up the noid light a fair bit brighter than mine does.
