Hello Wayne,

Could be a number of things.

Alternator, or charging wire burning out, we used to replace this wire in the harness.

Check for poor engine ground at the rh side of block.

Check for burnt battery feed wires at the fusebox.

Hi checked all them, new battery now , old one dropped cell, new fuel filter, still same, then changed fuel pump , it ran better but, still losing acceleration after 20 minutes of driving, but I pull over, turn off engine then starts straight up again n accelerates fine again for a few mile then start losing pedal power again, it idles fine, no miss, its like its starving for fuel once warmed up, fuel pressure??
AU Auto Mechanic: Gary, Australia Car Mechanic replied 7 months ago

Hi Wayne,

Did you change the strainer for the fuel pump?

I would clean the fuel tank out, since corrosion, junk etc could be blocking the strainer.

It falls off the strainer when you turn off the engine.

A fuel pressure gauge tee'd into the fuel rail will show what is happening.

Normal pressure at key on, or engine low rpm, and failing pressure after sometime points to a tank problem.

Could also be how the tank is venting.
