'89 4.0/AW4; 200k miles. I'll try to keep it short.
Stalled out while driving. Restarted twice, then no more.
Was thinking CPS/CPK, on the assumption that I had fuel and spark. Verified spark, and had pressure @ schroeder valve on fuel rail. May have been residual pressure though.
This morning she still cranks, but no start. No pressure from schroeder valve and I don't hear the fuel pump trying to prime.
How do I verify whether the pump is bad or not. Specifically, what relays/fuses may be at fault if pump is still good? Is there something that I can short/jump to see if the pump will prime?
Already gonna be late for work; hoping to keep that to a minimum.
EDIT: I get 218 ohms across CPK A & B. Only have DMM (no needle), so checking cranking voltage isn't gonna happen.
Thanks,
Brian
