Lifted this from the stickies, sounds exactly how my truck is acting. I'm gonna attempt to do some work on it tomorrow, but depends on if my back will be bothering me to much or not. Healthy IP is capable of pulling it's own fuel past a dead or weak lift provided it is GM flow on fail type...

Thanks I did'nt think the codes stored if the SES light did'nt stay on. I checked them this evening. 34-injection timing stepper motor fault 49-service throttle soon lamp circuit fault 57-PCM 5 volt shorted 62-turbo boost sensor circuit low I hav'nt been able to install a fuel pressure...

Ok I'm back with another issue. I searched the forums but can't quit figure out if my issue is what I think it is. I noticed here about a week ago that the truck would stall when I got on it hard sometimes. Also every once in a while it would die shortly after start just idling in the driveway...

No codes, no ses light.

His products are great. I have the PMD cable ,cooler and Dtech PMD. Also the Turbo Boost Bolt and OPS extension hose all from Leroy.

I started cleaning the grounds from the frame to the engine and cab. Got the contacts at the frame clean and I can't get to the ends attached to the back of the head or the cab, so I decided to go with a hunch. I recently replaced the glow plug controller. It turned out that it wasn't the...

The only reason I have'nt checked the grounds is cause I just cleaned the and redone them a few weeks ago, But I will check them out tomorrow morning. Certainly makes sense.

Tried to crank the truck today and the the glow plug light never came on. It turns over but won't start. It's been starting fine the past few days, but the glow plug light would only come on for a few seconds. I checked the fuse and it's not popped, but there is no power coming to it when I...

I've been running it this way for about 3 weeks and thats the first time it throug a code. Guess cause it was at that high for a longer period of time. It regulary sees around ten when I'm driving the freeway because I throttle up quite often when dring in traffic (inpatient driver). I'm gonna...

I like this post, I need to get the same thing for mine, the wiring to some of my glow plugs is a bit ratty.

Threw a code 78 today while on the beltway. Looked it up and its a turbo boost solenoid failure, ok, but I have a manual wastegate controller on my turbo. An I pushing too much boost? should I dial it back a little? I think the most I've seem it hit was 13, but I have'nt put my foot in it as...

I want to rewire the glow plugs. Some of mine have bare spots and I don't think they are get all the juice they should. Is there a specific type of wire your supposed to use for these?

LOL, yeah that fuse goes to too much shit! Me and my cousin traced all the wiring from it for about 2 hours till we found it.

Finally, after a week and a bunch of BS on my part, IT RUNS again. Til the next time it breaks. Thanks for the suggestions guys.

Cool, I'm gonna give it a shot in a bit then. Last night by the time we found the short the batteries had gotten too weak.

Got some help with the truck yesterday evening. My cousin came over and helped me chase the short. Looks like its in the fuel heater on the bottom of the fuel filter housing. Is the fuel heater necessary for the truck to run?

Anyone got a schematic for the 1994 6.5, my manual only has the gas truck schemes.

Got the Alternator tested, it's good. Ohm'd the A port it comes out 0. Tried unplugging things 1 at a time and turning the ignition on. Unplugged the OPS, glow plug controller, both temp sensors, LP, and no change. The truck still won't start. Turns over and blows whitish smoke out the exhaust...

The OPS is only about 2 weeks old, could it be faulty?

I changed the glow plug controller and plugs today and changed the gauges fuse. As soon as the ignition is turned on the fuse blows, and the truck still don't start. I jumped the lift pump and it still puts out as much flow as it did when I got the truck. I can't tell you exact psi cause I don't...
