Testing Update.
1. Added about 4 gallons of fresh fuel. Tank is now full

2. Checked the Fuel filter for blockages.
Results: Looked clean (changed 8 months ago with pump)

3. Checked the FP with a fused jumper wire and gauge on the fuel rail. Ignition off.
Results: Gauge went to 54psi and could hear fuel returning to the tank. Removed jumper. The test gauge leveled off to 50psi after 5 mins and holding.

Now, Im checking the relays again. New FP relay installed yesterday & fuse is new.
I do have a backup OVP relay in my box somewhere. Will install and test for OVP failure.

Where is the Cam sensor located?

New Update: After 30 minutes, the fuel pressure has dropped to 42psi. Im loosing pressure slowly. Would the injector seals cause this?
