This is a cross post to multiple sites.
'74 2.0L with stock d-jet. Just installed a new (at least that's how it was advertised) original type 3 port fuel pump in the original rear location and now car won't start. Pump comes on, engine cranks very strong, but no start. There is good fuel flow to the pump, but no fuel to the passenger fuel rail. It seems that all the fuel is going to the return line back to the tank. Any thoughts?? Paul |

No markings? Yikes, that sucks!
The R port is the one that has the silver "hat" on the side next to it. Your pic says you have that one hooked up right. The pumps should be set up the same way, because of where the inlet/outlet are relative to the pump rotor. (Brings to mind another question: Has this pump been taken apart? If so, could have been assembled incorrectly. Did that on mine.) The bypass is a spring-loaded valve. The spring and I think the valve are under that silver cap on the side of the housing. You may be able to take the cap off and free up a stuck valve, but I'm not sure how you get the cap to stay on again afterward. --DD |
