Car had been running well until it would not start. It initially started but sputtered, then nothing. I did not try to start again for about 4 month’s. I tried again, it started, I washed, waxed and went to fill up before a show. After waiting 3 1/2 hours for a tow at the gas station, it hasn’t started since. I tell this story only for background leading up to my question.

Tested Fuel Pump Relay and no power to the 87 pin for the 1-1 1/2 seconds when key is turned. The 86 pin has 12V when key turned and 12V to power relay under back seat.

I tested fuel pump directly and it appears to work fine when it has 12V

Replaced Furl Pump Relay and I get power to the 87 pin for the 1 - 1 1/2 seconds. Car still doesn’t start. Check voltage to 87 pin again and I’m only getting about 5V for the 1-1 1/2 seconds. Should I be getting 12V? If I should have 12V, suggestions on why I not and what I should check next?

Any help is appreciated
