Fuel System Help Please

[BamaStang]

I have got a 89 lx fuel pump will not prime or come on, replaced fuel filter& pump turn the key on& the relay under the seat clicks but nothing else?

Any help would be greatly appreciated.

Are you getting power to the pump?

I like to start at the FP relay with stuff like this. I probe the terminals in the relay socket (during the prime-out) and note the values.

Jrichker's no start checklist will be of great assistance to you.
Good luck.

Your answer is in the post you posted in 5.0 Tech. Follow the checklist and you will find & fix the problem.

check the inertia switch mounted behind the taillight panel. Make sure it is pressed.
