The leak is showing up on the top front left part of my 4.3 Vortec Z engine.Like right next to the Thermostat housing.Is it possible the Lower intake Manifold could be leaking. the engine runs fine other than the leak.
After reading some of the responses it might be a worn wire in the steering column from the ignition switch.
In the mean while try this, turn key to run, shift into neutral, then start, might work.
in the boots that join the wires at the battery and at the terminal block behind the right head light. I replaced all the cables and cleaned the connections, then I sprayed with sealer to stop the problem again.
Bitter
and have someone crank the engine, if the rotor turns inside the dist, it means the chain hasn't broken !
If you have no compression and the rotor doesn't turn in dist when you crank the engine then you have a broken timing chain !
My '97 S-10 was stalling at high revs. The engine would just give out, the lights on the dash would light up, and for a few seconds the car would drift and then jump start itself.
I went to AutoZone and was ready to buy oxygen sensors, fuel filter, air filter, spark plugs . . . all the things I would think that could be the problem and I know hadn't been taken care of in a long time. Figured there was a good probability that one or multiples of them would be the cause. The guy at the AutoZone save me a world of grief AND MONEY! Since the engine light had come on, he said he could just hook up the diagnostics and tell me what was going on. Good thing he did because, there's no way I would have that the problem was the one he diagnosed.
It turned out to be the crankshaft sensor (I didn't even know there was one). It was a real pain to change out. It hides underneath the engine below the distributor cap and is NOT user friendly to exchange. But ultimately I did the job and the car is happy and normal.
I guess they deserve the plug for all the money and time they saved me . . . THANK YOU AUTOZONE!
I was able to get it to start. I simply disconnected the fuel injectors and let it start using all the fuel they had been pumping in. It seems as if it gets hot and then starts flooding itself. Is this a MAP sensor issue? Once it was running, I reconnected the injectors and it ran for about 2-3 minujtes before dying again. It seems to be running at about 1200 rpm (really high).
Any ideas? What controls the injector behavior?
Lean, fuel filter, fuel pump.
