I have a 1986 Buick Park Ave 3.8L It turns over but it won't Start. I have
fuel coming up to the injectors, I also checked for spark and I also have
spark in every cylinder. No codes came up on the code scan.
Could the timing chain jumped a tooth on the sprocket or could the timing
sensor be gone. Is there any way of checking both of those. The car only has
150 000KM on the motor.
If you have good spark, the crank sensor has to be ok, now you must check
for fuel pressure in the rail, or spray carb cleaner in the intake and see
if it starts, a noid lite is a plug in device that goes in the connector at
the injector harness to check for a signal and pulse from the ecm.
