Lots of searching on this one. Mine seems to be difffernt than the usual CPS or fuel pump issues. 99 D1 w/ 107k. This is issue been going on last month or so. Sometimes it starts right up. Other times it just cranks and cranks with no turn over.
Pulling random numbers from the shrader valve. Sometimes I?m getting 34psi other times I?m getting 28. Sometimes only 10psi when in on (position 2). If I let the pump prime in the one position for 3-4s, it usually starts up no problem. However, if I try start it without pausing in the on position, it?ll crank but not turn over. Once I cut it off, I immediately lose pressure in the system. When?s the rover is running, it sits about 28psi. Idles great and drives great as well. Power is fine. I can audibly hear the pump running as well.
I replaced the pump only with a known good used pump. Also replaced the fuel relay with a used part just to x that out. New fuel filter. New battery. Starter and alternator test fine. No change.
Does this sound like a bad fuel regulator? Is there a relay or valve in the sending unit itself that isn?t holding pressure? Thanks for help in advance.
