3.8 v6 convertable

it cranks fine but wont start, we are getting 12v at fuel pump connector for a few sec when key is swicched on, we replaced the pump and the new pump runs fine when hooked up to independent power source but dosnt run when plugged into car harness, we also replaced the fuel pump fuse and relay, anyone have ideas?

 

break in the line??? faulty ground??? could be a million things

 

The PCM will automatically shut down the pump if the engine does not start within 5 seconds. What you are seeing with the fuel pump is normal for an engine that fails to start. Make sure you a good spark at the plugs, good fuel pressure at the fuel rail, check the injector fuses, verify that the injectors are being fired.

 

i know that we are getting a good spark, will check into the other stuff hopefully tommorow and let u know if it dosnt work XD

edit: the car also runs with an outside power source
