Hello everyone... First time posting here.
This vehicle died on the road and hadn't shown a sign of loss of power, fuel leaks, etc..
What I've done and noticed:
1. Getting 2 codes, P2291 and P0627.
2. Noticed tank sucked in, possible cap not able to breath or release pressure. Released cap and heard air/vacuum being released.
3. Replaced both fuel filters.
4. Replaced pressure regulator on left side rear rail.
5. Noticed no rust nor metal on regulator valve on rear of left side rail.
6. Replaced HPFP from a used engine (metal particles evident on old pump, rollers were gone).
7. All fuses and relays are ok.
8. Unable to test for actual fuel pressure on the low side, but there's plenty going to the fuel system.
9. Disconnected fuel pressure sensor, still no start
I know all parts should be replaced, but we're trying to stay on the low side of costs.
Any help is greatly appreciated. I've read through other posts and still can't reach a fix. I'm going to tap into the output of the secondary filter and see actual pressure. I'm assuming it's suppose to be 50-75 psi correct?,
Thanks,
Ben
