My car wont stay running unless I prime it. I have changed the fuel pump, fuel filter, fuel module, and the ignition coil. Any ideas on what else could be causing the problem?

Have you confirmed that the fuel pressure is within spec? It sounds like it is weak which may be the result of a bad pressure regulator.

No we haven't checked the pressure but we also replaced the regulator.

I would check it. I have seen many times that the pump produces enough pressure to keep the engine going once started but can't produce enough to start the engine.
