When my 73 2.0 gets driven for about 25-35 minutes it shuts off and the fuel pump wont come back on until sitting over night, does anyone know what might be the problem thank you very much in advance.

Hmmm, have you checked grounds? Like the trans strap and the starter wires...pulled the relays on the circuit board? Also...but less likely, when was the last fuel filter changed....if you do cut it open and see how crud is in there....

The grounds are good, its got new fuel filters and lines, fuel pump is relocated up front, and yes i have pulled the relays off, and checked them and replaced them, nothing changes.Any other suggestions?

would carbs maybe solve the problem i really need help.

Front or engine area mounted FP? (don't remember when the 914 went to front mounted FP).

If engine compartment mounted, heat related vapor lock.

Problem: Ballast resistor powered FP.
Solution: Wire your own from ign switch to FP.


No but seriously.. What else would shut OFF a FP?


Couldn't you still hear it even with vapor lock?

When the car dies, check to see if you have power to the fuel pump, if you do and the pump really has stopped running, I would look at the pump or fuel system. If you don't have power, then I would check the wiring and fuel pump circuits for a problem. At least you could narrow it down.

What is the ballast resistor? could you go more into detail. Also if it is only dying when warmed up would that really be the circuits?. Finally the fuel pump is up front.
