Brand new motor, blueish smoke ???????

[stroker342gt]

bout 150 miles, been doing it since it started back up. Brand new GTP38R. Brand new bottom end built by Diesel Innovations. And no my old motor grenaded a piston. It shut off tonight without warning and wont start back.

It's fairly common with a new engine as the piston rings begin to seat. The thing about cylinder walls is that they have to be smooth to seal correctly. A new engine has very rough surfaces on the cylinder walls that hold a lot of oil that the piston rings cannot get to (wipe away). Give the engine 1500 miles to get a bit of glaze to the cylinder walls and then see where you are with the smoke. It can also be valve guides or seals (I know you had them redone......)

Does your wait to start light come on and go off? Does your fuel pump turn on (you should be able to hear it run for 20 seconds when you turn the key on)? Does the tachometer needle move while cranking?

Let us know what you come up with on the WTS light and fuel pump and we'll go from there.

Yep wts light and fuel pump(pulled the cap on the fuel bowl and its pumping in like normal) are working fine, can hear the gpr under the hood. put a scanner on it and it threw no codes. Someone told me an idm box but i dont know how to check it and its way to expensive to just go get one to see if its the problem. Thanks

I wouldn't start throwing parts at it yet. What are you using for a scanner? I have some things for you to watch.

[stroker342gt]

ive just got a lil cheap orielys scanner. dont have the money for anything big right now after all this just past. Anything i can just check?

Watch the tach to be sure it is jumping up while cranking.

Is the oil pressure "gauge" showing oil pressure while cranking?

Hows the cranking speed......... nice and fast with no flickering lights on the dash?

[stroker342gt]

Tach isnt moving. Oil pressure gauge isnt moving. cranking is like normal speed, no lights. new issue is the rear cargo light is staying partially lit, "off" light in pass. side air bag switch is staying partially lit, radio is staying on, and some about 4x4" box with three connectors on it is clicking that is located in front of the drivers side battery box down behind the park light.
