truck wont start unless i use starting fluide and runs rough

[02stroke87]

Ok my truck started running rough like it had water and lost power, two days after this happened it wouldnt start unless i used starting fluid, i changed the ipr, and icp and still no change., the last code it pulled up said something about the idm, what do you guys think.

That you might've damaged it past repair for using starting fluid

Checked your UVCHs? Fuel filter? Pump?

First, Seriously,,,, you just gotta Stop using starting fluid before you do Serious damage to your motor...

Next, the most common IDM code is 1316 and that's just telling you you need to do a buzz test for the IDM to resolve the specific codes needed (unfortunately you need a professional scanner to do this. Maybe you have one?)

BUT, the most common IDM issues with our trucks are the connections, Thru the Valve Cover gasket, to the injectors. Get it running (try propane, WD40, BrakeClean, ANYTHING but either) and check the "heat" in the exhaust manifold for each side and compare them. The cool one is the side that's not firing (IF that's your problem) and you need to remove the VC to see if it's burnt or just unplugged.

That's where I'd start...

so either is a bad idea? didnt think one little shot would hurt it? didnt know i could use brake cleaner or wd40 to start it, how do i go about checking the heat on the manifolds, i do not have a professional scanner, thanks

It's a very bad idea. It can be predetonated by the glow plugs, and blow seals or a piston. One shot is all it takes.
You can feel the manifolds or an infrared thermometer

thanks, so i can just spray wd40 or brake cleaner in the intake and it will do the same thing but wont hurt it.

[jesilvas]

Don't spray anything. Fix it.

Simplest thing would be to just open the hood, get it running for like 30sec, jump out and put your hand on each side

If both sides are firing, they should be the same temp....

Still could be many things, just an easy thing to check for a common problem. Did you look at the youtube vid?

Thanks and yes i did watch it. sounds just like my truck when it is running. i lucked into finding someone to put it on his computer for free today so hopefully no more guessing game. thanks again
