Another update:
I loaned a fuel pressure gauge from AutoZone.
My fuel pressure barely gets to 10psi when I turn key no start. It then automatically drops.
When truck is running I’m at 18PSI.
I changed out the FPR with injectors. When I got to the original, I found the vacuum line was open to air.
Didn’t test fuel pressure prior. Could it be the the FPR is faulty?
please note: the truck ran fine other than slight hesitation from stand still. So I’m trying to rule out fuel pump.
Plus the previous owner “said” he changed the fuel pump.
Thoughts???
Fuel pressure doesn’t hold at all. Drops to zero as soon as I shut off truck. Don’t even need to release pressure in gauge…..
