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 |

My bet is that you got the hoses on the wrong fittings of the pump. Either that, or the electrical plug is in backwards...
Not that I've ever done either of those myself. More than six times. --DD |

Port at relief valve to "Y" to return line to tank. Top port (away from electrical plug) to fuel filter outlet. Are all "original" type 3 port pumps configured the same, that is, are the ports are in the same locations? This pump has no ID markings on the 3 ports. If the bypass is staying open, how can that be fixed?? Paul |
