Refined Trucker Posted October 16, 2015 Share Posted October 16, 2015 Sounds like an injector laying down. Quote Link to comment https://www.bigmacktrucks.com/topic/42213-e-7-400-smoking/#findComment-307615 Share on other sites More sharing options...
turckster Posted October 16, 2015 Share Posted October 16, 2015 If it is an electronic engine (vmac1&2) I would say the TEM sensor may be bad. Low fuel pressure and timing come to mind as well. It all depends on the color of smoke. A light blue haze and I would say its burning oil. White smoke and it is either a timing issue or low fuel pressure. Black smoke and its excessive fuel or lack of air. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/42213-e-7-400-smoking/#findComment-307634 Share on other sites More sharing options...

Kansas farmer Posted October 19, 2015 Share Posted October 19, 2015 The econo advance advances the timing. I had to replace those same things on my 400. Does the malfunction light come on? I had a broken piston in the fuel pump. But it was acting just like yours.

idigm Posted October 20, 2015 Author Share Posted October 20, 2015 yes the engine light comes on after starting and running for about five seconds, then it starts to run badly and white smoke.

Dieselwrenches Posted November 12, 2015 Share Posted November 12, 2015 Did you try tem sensor like truckster suggested, I would go there next. Doing injectors isn't a bad idea either.

idigm Posted November 13, 2015 Author Share Posted November 13, 2015 TEM sensor changed not it ! if they put 12 volts direst to econo advance it cleans up and runs good but still shows 31 degrees advance on idle and they have checked wires from ECM to econo adv and are good, ECM is also good ???? The dealer is stumped !! Quote Link to comment https://www.bigmacktrucks.com/topic/42213-e-7-400-smoking/#findComment-311192 Share on other sites More sharing options...
Dieselwrenches Posted November 13, 2015 Share Posted November 13, 2015 Did the solenoid for econo adv get changed? Quote Link to comment https://www.bigmacktrucks.com/topic/42213-e-7-400-smoking/#findComment-311196 Share on other sites More sharing options...
gearhead204 Posted November 13, 2015 Share Posted November 13, 2015 it sounds like the timing is stuck or the air flow is restricted Quote Link to comment https://www.bigmacktrucks.com/topic/42213-e-7-400-smoking/#findComment-311211 Share on other sites More sharing options...
idigm Posted November 13, 2015 Author Share Posted November 13, 2015 (edited) now they tell me that the flywheel has no marks in it for the flywheel sensor to read and they think that is most of the problem, They say it needs two references to properly time the motor flywheel and sensor on the fuel pump?? And yes there is a new econo advance on the motor.

idigm Posted November 22, 2015 Author Share Posted November 22, 2015 So here is the results !! Someone who owned the truck before me put a new clutch in and changed the flywheel put one in that did not have the timing slots in it and it could not pic up timing at the flywheel only at the TEM sensor, changed flywheel to one with timing notches on it PROBLEM SOLVED !!
