I removed the solinoid kill switch last week and had pressure there and a lot spilled out.I reinstalled and the Truck cranked and ran for an hour.I turned off recranked it started. Next day no start.Thought its solinoid is failing.Bought new one replaced,cranked and cranked,nothing.Wasted money. HELP!
AnswerHi
Make sure the lift pump is pumping at all times (Located on frame, under drivers seat area)
You should physically feel it "thumping" while the truck is turning over.
If so get truck scanned for codes.
If not, make sure it is getting power.
If so you have a bad pump.
If not it is PROBABALLY the oil pressure switch, located on rear of engine where a distributor would go on a small block checy engine.
If you get codes checked, please post back with codes #'s and I'll assist you.
