Cheyenne Has No Gas
Q. Mr. Ciulla, I am currently having a problem with my truck starting. It is a 1989 Chevrolet Cheyenne, 4.3 liter, V-6, 2WD. About three weeks ago, when the problem first occurred, I put fuel in the carburetor and it started fine. But since it happened again, I thought it might be that the fuel filter may be clogged since I had the problem before.
The truck still has not started. In an attempt to identify the problem, I disconnected the fuel line at the filter and checked to see if the fuel pump was working but I don't know if that was the right thing to do to check the pump. (There was no fuel that came out when I cranked it.)
Do you have any pointers that I can test or try out to get my Chevy on the road again?
Thanks,
CrisA. Well, I'm going to assume you replaced the fuel filter Cris and that was not the problem.
Basically you found the problem, there is no fuel getting to the engine. The first thing to do is to see if the fuel pump is running. If you get down by the gas tank and listen while someone cranks the engine, you should hear it run. If not, then you probably have a bad fuel pump relay. If you do hear the pump running and no fuel comes out, you may have one of two problems.
The first, obviously, is a bad fuel pump. The other may be the result of the in tank fuel pump becoming uncoupled from the fuel tank sender assembly. In either case the tank will have to come out to make the repair. This was a problem with all 1989 trucks with TBI.
