I was having intermittent trouble with the car not starting. I noticed that when the key was in run I could hear the fuel pump engage(prime?) Then the car started and ran fine. Occasionally, in RUN I could not hear the pump that's when the car turned but would not start. I figured the fuel pump was going out so I replaced it. No change so I checked the voltage to pump. None. No voltage to fuel pump relay, either. Any ideas?

Check the fuel injector harness pink and black wire for power if there's none inspect and test the FP/Injector fuse this fuse powers both the relay/injector

Checked the wire - no voltage. The fuse tests good.
Also, the temp. And fuel guages don't seem to respond when the ignition is on.

You check for voltage no voltage at injector and fuse tests okay-does the fuse has power on both ends when key at run position no power probably the ignition switch.

That was it! Thank you very much. I had just replaced the ignition switch about 4 months ago from Autozone. That's why I didn't imagine it being the switch again. Are OEM ignition swithces better. Thanks again, I'm sending donation.
