My truck wouldn't start. We went through the whole replace coil, spark plugs, check distributor, wires, replace fuel filter, and it ended up starting with ether. So we replaced the fuel pump. Now it starts great but while driving, under load the truck now does a sort of like miss, type of small jump in the motor. Kinda like a putt. LOL I'm a girl ok! This has been a great truck for me so it running sorta a little bad is unusual. Also the fuel gauge is spinning like a top. Are they connected? My man knows engines etc, but he is not a pro. I filled up the tank with gas thinking that would maybe solve the problem, but no. Any ideas?

Has the check engine light come on? Have you checked for vacuum leaks? Also, the fuel pump and the float gauge are one unit. If the problem started after replacing the fuel pump, I would say you got a bad one or you pinched a wire when replacing the tank.

Check that out and let me know what you find.

He is going to take the pump unit out again tomorrow. He is going to go through the unit again and check things out. I will take it to autozone and get a reading of the computer. The check engine light is always on because I have a custom exhaust on the truck and no catalytic converter. We'll see what happens.

The miss is from rich gas. No O2 sensors so medium grade gas caused it to miss. Went back to cheap gas. Havent done the gas tank yet. We may need to replace the entire fuel pump assembly unit.
