Hi guy's, I'm new here.

I have just aqured an old AE82 and fitted a 4age 16v bigport to it.

I have changed the whole wiring loom (Engine bay and Dashboard) and fuse boxes (3) and i can only get it to start on thr cold start injector.

It starts for about 1-2 seconds then stops.

I believe i have tracked the problem down to the No 2 EFI relay. The relay tests and works fine on the bench but, I cannot get power to it thru footwell fusebox. I replaced that fusebox and still no pwer to the relay.

 

Any Ideas????

 

PS. I have positive battery current at both sides of thr injector plug and no pulsing during cranking.

Hi Guy's, I know I did not get a reply but in the time since then I have found several things.

1. Australian AE 82s don't have a No 2 EFI relay. (Only Japan US and Europe)

2. Checking the injector signal is nearly impossible unless you have speacilised EFI test equipment.

 

Anyway I fixed the problem by running full fuel pressure (Fuel pump Relay bypass) and signaling each injector several time each using an adapter I made.

After doing this the engine now runs very well.

It appears that the injectors may have been a little gummed up or sticky.

 

Cheers,
