Hey guys here's the problem. I have a 1988 Ford F-150 4 wheel drive 5.0 engine. When I shut it off sometimes the dirty Bitch don't want to start. I have replaced the fuel pump relay already. Then if you let it sit for awhile it will start again. When you turn the key to On position when it won't start the fuel pump you can't hear it running. Is there anything else that you folks can guide me to fix this miserable problem
Thanks
Uno
