I've got a 2000 Excursion 7.3L running a DIY conversion (deadheaded). Before I converted the rig, I was getting an intermittent CEL code P0673 for glow plug circuit fault in cylinder 3. It came on for a few days, went off for a few months, came on for a few days went off for a few months. Then I completed my conversion and have run roughly 100 gal through my system. I'm also having some heat-related issues, having trouble getting my temps up:
Low WVO Temps
So I've been tweaking my system here and there and in the course of testing things out have probably run some cooler-than-desired oil through the engine (let's say 130 degrees).
My CEL just came back on and threw me two codes this time, the P0673, and also the P1280, which I understand is an Injector Control Pressure sensor. Here's the $10,000 question: could my conversion be causing this CEL, and am I ruining my injectors?
Ever since I've converted my rig, I've been driving around paranoid that I'm ruining my nice PS7.3L engine...(and also paranoid that my WVO tank is going to fall off the underside of my chasis! I've had two WVO leaks which have helped to feed this paranoia, one in a very embarassing stop-and-go traffic situation with LOTS of bystanders
luckily isolated to the WVO so I could still drive out on diesel)
Any insight would be appreciated.
