if my injector harness has come loose when I use a scanner will it throw any codes? They told me glow plug circuit and back pressure circuit and #2 injector. Has any one had or heard of a problem like this
My bet is the harness. It will affect your injectors and GPs. My was acting crazy as hell. And was very intermittent. Get a harness from Oriely's or advance. And save some coin. Yes they are made in China just like the Ford ones. The plastic is very brittle so be carefull. So dont waste your time with the $.25 fix. You get the valve cover gasket and harness with the kit. Dont be dumb like me and not replace your GPs while they are right there. I think I paid ike $150 for the kit. GPs are around $50 a set I think. My harness outside of the valve cover seemed to be in good shape. So I didn't splice a new connector on that side. The exposure to all that heat kills the plastic under the valve cover. I could do it now in well under 2 hours. The first time took me about 3. Those rear bolts require a swivel and lots of paitence:thumb:
As those connections are failing, you can burn the contacts and they really do have to be replaced. BUT the 50cent mod works really well if they're in decent shape. Here's a good vid.
