4age help ( WEIRD! )

[dirty_86]

Car : Toyota Sprinter AE86
Engine : AE82 4A-GE ( MAP )
Computer: Stock AE82 Computer
Fuel Pump: VL commodore
Lift Pump : Fuel Flow

Problem:

Car starts nicely after 3 seconds the car dies. The open circuit relay for the fuel pump clicks on and off, fuses are fine. Its a fuel problem i know that for sure but heres the catch. We put a noid light / test light on the relay with accessories on and the fuel pump started to pump. So i thought start it up with the test light running the pump. It WORKED!.. i took off the noid light / test light 3 seconds later the car died again. Is this a grounding problem?

Help would be much appreciated

cheers

Where are you running your neg wire from the fuel pump, im just guessing your using an external the same as mine (VL).

[dirty_86]

yes it is an external and the neg is grounded near the pump on the body.

Its sounds like the same problem as i had with daves (ajps).

Check that while the ignition is on that you have 12v positive power at the injectors and they maybe a bit of a feed back through the other wire.

If there is no power find the yellow wire that goes to the injectors at the ECU and put a fused power to that.

Its abit hard to explain other the net. So if you have anymore probly PM and ill give u my mobile number and you can give me a call

hey thanks for that

but 1 of the first things i checked was power to injectors while ignition and there is 12v..

cheers
