Reader Question

Good morning,

I have a 1997 F250 HD with a 351, my problem is this. The truck started knocking and pinging and eventually stalling, at first it would start right up then it would take about twenty minutes of sitting before it would start. I changed the fuel filter it seemed to work for a while but now it starts and runs but will not start once I shut it off but if I let it sit over night it will start again. I am not sure if it is a fuel issue or electrical or what? Any advice will be greatly appreciated.
Thank you
David

Hi there David

If you don’t have a service soon light on, I would first start with checking fuel pressure at the engine with a fuel pressure gauge. You could have a weak/bad fuel pump. If you do have a service light on, I would first read your computer codes. Although, you could have a service light/code stored in memory because of the knocking and stalling issue which is a symptom not the cause. Sometimes you can bang on the bottom of the fuel tank with your fist or block of wood AS someone is cranking the engine over. this can help jump start a weak fuel pump.
