QuestionI have a 92 buick Lasabre 3.3L and I am having issues getting it started. The fuel
pump was checked and the fuel filter was just changed. I am getting plenty of
spark, and the car will run off ether. I suspect that the injectors are not getting
any power, because the plugs are bone dry after cranking the engine. (All six)
Any insight would be greatly appreciated!
AnswerI assume you have checked the inj fuse, or checked for power at the injectors when the key is in run?
You say it runs on either. Just for the duration of the either, or does it continue to run after starting on the either?
And I would check the fuel pressure with a tester if it hasn't been done that way. The correct pressure is a must.
The crankshaft position sensor sends a signal to the ECM, which pulses the injectors accordingly, so make sure it is connected.
And make sure the egr valve isn't stuck open, which is a huge vacuum leak if it is.
