There is none in line is low oil pressure shut off, relay and the pump if it is not working then either the oil pressure switch is bad or the pump has gone out

i had the same problem and replaced the fuel pressure regulator. Cost about $45 at advance auto store or about $90 at napa auto stores. Once i replace that my truck started right yup and runs like a champ

Purchase new egr valve gasket with screen on it. The motor as it get older produces more carbon it then begins to break off and when the valve opens it get caught in there. i have cleaned mine several times and finally found the gasket at napa for around 22 bucks. All you need it 10mm wrech and 10mm socket with ext. takes around 10 min to do.

fuse in the fuse box. also the power to prime the pump starts at the oil pressure switch. check that out too. then the relay for the pump in that order
