First thing in the morning or after it's been sitting for long periods of time my 780 starts fine. After it's been started it takes about 15 seconds of constant cranking to fire up. Only thing I can think of is injector leakage. I do have blue smoke when I fire it up at temp and I know that is too much fuel. any thoughts on an easy fix or chemical I can use in the tank to clean the injectors for a temp fix? Money is tight so new injectors is out of the question. Also as far as I know the v6 in my 780 was only used in this car. Not sure if there are any aftermarket injectors out there. Everything I seem to buy for this thing is factory direct and that causes a serious price hike.

 

Blue is not unburned fuel/rich condition.
Blue=Burned oil
Black=Rich/unburned hydrocarbons
White=condensation, coolant or someone poured transmission fluid into your gas tank.
I will stop short of saying injectors don't leak but I will bring up it is much less common than folks think. Anyway, injectors either leak or don't. The temp of the engine would not alter leakage. I would suspect the ECS (engine coolant sensor). Before I went too far, I'd pull the plugs; if you're burning oil, they may be fouled incredibly.

 

After reading your post I rechecked the color and it is black. Engine coolant sensor is new. Not to say it is good but new it is. Sparks plugs are the next thing to check on my list. I drove it roughly 340 miles today and it drove great. Got decent milage too. It's just that pesky hard start at op temp.

thanks for the clarification.

 

Your starting problem could be the Fuel Pressure Regulator, at least in a B230 it'd be....

That engine was also used in AMC Eagle Premier and Delorean cars. Also other Peugeut/Renault variants in Europe.

 

That is very good to know. Thanks for that info.
