so the usually means relay. but you said it was good.

also the tfi module can cause the pump not to run.

Might be the fuse for the pump?

Mine primed with a bad tfi module.

maybe fuse. when i changed my distributor to msd for carbed setup that deletes the tfi, my pump wouldnt run no more. at the time i didnt even realize that anything was still running through the ecu. but after some studying i found that the module sends a signal to the ecu which then sends to the relay. this is a ground signal. my fix to still use the factory relay was to take the signal wire between the ecu and relay and put it straight to ground. the only downfall was that the pump will run as soon as the key is forward. but i installed a kill switch. also during this learning curve my pump would still do the 2 second prime but not trigger to keep running.

We grounded the relay for the fuel pump and then the fuel pump and injectors both kicked on whereas before we were just grounding the fuel pump in the hatch but we still weren't able to get it to start
