Under valve cover harness
2000 F250 160,000 miles
First off, I've been doing searches and there and many different scenarios and answers, so I'm starting my own thread.
I've got a hard cold start. If it's below 35* it absolutely won't start unless it's plugged in. The GPR tested good, so I tested the drivers side under valve cover harness. The #5 glow plug is bad, as it showed open, and I verified it by using a test light hooked up the the battery. My question is about the other 3 plugs on that side.
6-8 all read very high resistance (22-24 ohms), so would that mean the harness is bad, rather than having 4 bad glow plugs? I was about to test the passenger side, but got called to work and haven't been able to.
