I just got a buddy of mines 3.0 rebuilt and and am the process of trying to get it started.
The engine is in a 88 x-cab pickup with 4x4 and manual trans.
It will run off of the cold start injector for a few seconds then dies and will not fire no matter how long you crank. If you recycle the key, it will try to start again for a few seconds and die.
What I know.
I have fuel and the fuel pump has power when cranking.
I have spark, tested with spark tester.
I do not have injector pulse with noid light.
I do have power to the injectors.
Grounds are good unless I forgot to hook one up. I have 4, engine ground to battery, RH side rear of engine camshaft cap bolt, LH side engine to left fender, rear of intake to firewall via connector.
I understand the distributor sends signal to the ECM to pulse injectors, is there a way to test this. Pickups seem to be good.
All fuses are good.
Timing belt is new.
Cap, rotor and plugs new.
This truck had an after market security system on it and buddy cut the wires and pulled it out. Can't really find any wires where they shouldn't be.
It runs good when it runs, just doesn't run very long.
Any ideas would be appreciated.
