1995 CHEVROLET TRUCK

I bought this turck new. When it was a couple years old, I had an incident or two when it would not start (battery fine, accesories work, but when you hold the ingition to start you get nothing). Within a few seconds or minute, it started. After another year or two, it happened to me again (a few times within a one or two week period). It then seemed to happen very rarely from year to year.

It has happened a lot this year. And lately when it happens, it can take hours before it will start. Generally, it is just a matter of driving my car instead and a few hours later (without doing anything), it will start. Is this a bad sensor or something? Help!

My '94 was doing the same thing last year. Try banging on the fuel tank right below the fuel pump. Kick up at the tank or bang it with a broom. If it starts, it is the Fuel Pump/Sending Unit. The chevy trucks are known for this. I replaced the relay, and it didn't help, but a mechanic told me to kick the tank, and it started right up. It would act that way intermittently for months, and every time I would bang the bottom of the tank, it would start right up. The mechanic told me the Pump/Sending unit was probably "going". I changed them both, and problem is gone. Good Luck.

I replaced the relay and it didn't help. I'll try banging/kicking the gas tank. Where is the fuel pump/sending unit located?

Techman1 makes a good point with the rust.I also had to clean all the connections, as they were all corroded, so I may have been able to get away with cleaning and re-wiring the grounds and connections, but I figured if I already had the tank off, and the top of the sending unit looked pretty rusty, I may as well change it. Maybe by banging the tank, I was breaking off some rust, and "moving" the connectors or it was "freeing" something up on the pump. Who knows, but for sure changing the pump and sending unit and cleaning/replacing the connectors fixed it.

I got under the truck, had my wife turn the ignition on. I can hear the fuel pump. It appears to be working fine. I'm almoust sure it is the park/neutral switch/senor (whatever it is called). Where is it? Is there a way to bypass it?
