Pumps don’t turn on. Bypassed relay and everything works. Kinda thinking the ovp relay since the abs pump is kinda acting crazy. Ovp looks like original or at least in there a whole. If that isn’t it I’m out of ideas. What else would not flip the fuel pumps on?

Check fuel pressure and it’s 58psi with the engine off. Is that too high? Isn’t it soppose to be 46-52psi?

You can test the relay on the bench. Here's a wiring diagram with the pin numbers:

The fuel pump relay is switched on and off by the HFM control unit.

I swapped out the fp relay but nothing changed. On my searches the threads are pointing to the ovp as a no start with dead fuel pumps.
