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 |

Ok so you put a new pump in - chances are the problem is associated with that.
There is a failure mode on the 3 port pump where the bypass doesn't close and fuel does indeed just get pumped back to the tank. That should be easy to see by rigging up a collection system. Did your replace hoses or just plug in the old ones. If you replaced hoses 'while you were in there' it is easy to get the two tubes mixed up and wind up trying to push fuel backwards through the cct. |
