Oil pressure sending unit??????
Basically the truck shut off yesterday just after start up. I noticed some fuel leaking out the back so we traced it to the fuel filter. Took filter out and it was trashed(just bought the truck 2 weeks ago). Replaced filter. Learned how to prime buy jumping the wires on the oil pressure sending unit plug to supply 12 volts to the lift pump. Truck started no problem. Did a few more tests to figure out why it shut down in the first place and found that the lift pump is only getting 9volts. Is that correct or should it be seeing a constant 12 volt signal?
will be replacing the sending unit tomorrow to see if that makes a difference.
