Thanks for all your help. I'm now a little confused.
You are now saying that I don't have a Crank Shaft Position Sensor, or that it is on the timing cover. If it is on the timing cover, how would I locate it? If I don't have a CSPS then what may be the reason the car don't want to start. Here is my original post from June.
I have a 1994 Bravada 4.3 CPI Engine - Vin W, 135,000 miles on it. I own the car about 4 and a half years and is used mainly as a 2nd car and in winters. (4 wheel drive vehicle) About 3 months ago I was driving from Pa to NY, about 120 miles each way. It is mainly highway driving. I was near my destination on the highway, when it stalled out on me. I pulled over and it started right up. Then after I got off the highway, it started to stall out by every light and stop sign, and again it started right up each time.
On my way back home about 6 hours later, again it was doing the same thing. Once I got to the highway it ran fine for a about 105 miles. Once I got to my exit on the highway and got off, the car stalled out again. This time it would not start up. So I had it towed back to my house. The next day it started right up. I shut it off and I went to buy new spark plugs, distributor cap, rotor, ignition coil, PCV valve, and fuel filter. I had the fuel pump changed in May of 2005 (about 15,000 miles ago) The fuel pressure is 58 with IOEO. It still does not start. I do not have any engine light on.
I went to a salvage yard where you pull your own parts. I got a used Map sensor, IAC sensor, TPS sensor, EGR valve, CPI unit and a computer. It was from a vehicle that was in an accident. I changed parts one at a time. It still won't start. I checked the oil, I do smell gas in it. I know that means that there is a leak somewhere. I'm not sure what that means for car not starting.
I also read in your posts that it could be the Crankshaft Position Sensor. I have the Haynes repair manual and it does not mention anything about it. Can any one please tell me where it is and be specific about it and is it hard to change? Can someone also tell me if you could start the car with the Air intake plenum off the car, or does it have to be on and under pressure?"
So basically I changed everything that I thought might be causing it not to start. The only thing left was the CSPS. But now you say I might not have one. Do you have any other ideas why it may not start?
Thanks for all your help.
