Fuel Pump Not Priming, Need Help Please
When I turn the key to the ON position I do not hear the fuel pump prime. I applied 12v to the G terminal and heard the fuel pump run, so that works. I checked all the fuses under the dash, everything is okay there. I have replaced the fuel pump relay, still no fire. The engine runs when starting fluid is spray into the throttle body. But right now, it just cranks and doesn't fire up. So I need help with what to look for next. I read another thread that told to check the fuse by the battery and the radiator, but I could not find a fuse, only a relay. The car has been pretty healthy until this, nothing is rigged in the car so it should run fine. Thanks in advance for any help.

The fuse under the hood is inside a waterproof cap. Follow your pos battery wire til two smaller wire split off of it, one will goto the fuse. The split on car is abot 8 inches from the terminal.

Depending on what year you have, the fuse may also be mounted to the pass. Side fender right next to the battery in a weather tight connector.Be sure to look behind the relay that you found because the fuse is kinda hidden.

It was a 2 wire plug that was mounted to the passenger side fender. Sure enough, the fuse was blown. Changed out the fuse and it fired right up. Thanks for your help guys. Now on to upgrade the ignition.
