What are the resistance values of good vs. used glow plugs and injectors? I've got a strange hard to start issue on my 2000 F350, 7.3 and I'm making an attempt at a decision before I start pulling valve covers.
The truck has only one error code, a P0475, which shouldn't affect starting.
Currently, I've only checked the driver's side. Glow plugs are showing between 1.0 and 1.1 ohms. The injector solenoids are showing 3.4-3.5 ohms.
I bought the truck a couple of months ago. Odometer shows 102,000 miles. It's an extended cab. The truck looks good overall but is showing a bit of wear. Shocks, brakes, front suspension condition indicates original parts.
However, it had been sitting of a couple of years and mice/rats/squirrels had been busy eating insulation off of the wiring in the engine compartment. Got that taken care of along with rear brakes, shocks, and a front end rebuilt.
The truck runs well, not quite like the 2018 6.7 diesel the company furnished me with, but once started it does good considering the ~ 200 hp less it puts out.
Going to break it off here and get back out to the shop and check out the passenger side.
Those driver side numbers look great. I'd expect to see a problem there first.
Ok, hard start. Several aspects can contribute to that. Like temps in your location. And if the GP relay is working. That's my first suspect, the GP relay. When the truck is cold bridge the 2 big plugs on the GPR with a big screwdriver, maybe 20 seconds. That will power up the GPs even if the GP relay is bad. If it starts easy then we have a clue the GPR is bad. Be cautious when bridging the plugs on the GPR, that's full battery amps.
Sorry about not getting back, been rather busy the last few days.
I checked out the passenger side plugs and injector resistance, and they pretty much duplicate what I saw on the drivers side. For now, I will say that they are good. One thing I did notice is that the volt meter doesn't indicate much deflection when the gp's are powered up. Even shorting across the two main terminals doesn't show as much spark as I would expect. Maybe the GPR contacts have a bit higher resistance than they should. I have a NAPA GPR-109 (?) that I was going to use on another project and may put that on after I finish cleaning the fuel tank out.
Speaking of fuel tank, it was yucky, to say the least. Looked like a pint of chicken fat in the bottom plus about a handful of trash. While pulling the tank, I noticed that the suction line was very weak (more flexible may be a better description) at the connection to the line. I'm thinking that that issue may possibly be a part of the issue. As soon as I get the shop warmed up I'll check that out. 2000 F 350, 6 speed, 102K miles
