I have a 95 1500 that at first was shutting off while driving. When I would put it in park and turn it off it would fire right back up. This happened two different times. The last time it shut down 4 times in 2 miles. I replaced the TPS as someone suggested it to me. Truck ran fine for a week then would not start. I then replace the crank senor. Ran fine the next two days. Now this morning it will not start at all. Any suggestions of things to try or check? I am totally out of idea, also it is not giving a check engine light.

 

You might want to try replacing the cam position sensor. Have you checked your fuel pressure when it's acting up?

 

What would I need to check the fuel pressure? I know I have fuel coming to the shrader valve on the rail I checked that before I changed the crank sensor.

 

If it is the cam position sensor wouldn't it be giving a fail code?

 

You'd need a fuel pressure gauge that you can use right on that shrader valve. I don't think that's your main problem but just trying to eliminate possibilities (fuel pump going bad). Pressure should be above 40 or 45 psi if I remember correctly.

 

1995 trucks should have 39 psi for fuel pressure. 1996+ and up is 49 psi.

 

Cam/Crank sensors can fail, but, won't necessarily set a code.

 

I stand corrected! Thought he had 1999, I was looking at 1999's on craigslist earlier, got mixed up
