Hi guys any help will be appreciated.. HEres the story

I bought a Vortech V2 superhcarger kit Non intercooled 39# injectors. and installed it. A local tune made a tune so i can drive it until i get dyno tuned. After installing the supercharger when i drove it i noticed it felt like it was running very rich. It was backfiring here and there and it smelled like burned gas, I figured he made a rich tune so i wont lean out my engine. Now after driving it for 2 days the next morning i went to start it and as soon as it started it died. I was like wierd... Then i tried to start it again and it would just crank but wouldnt start. Uploaded the tune again.. and when i started it it died and this thick white smoke was coming out the passenger side exhaust and smelled like gas... Any ideas?

spark plugs might be fouled, pull one out and
check it's condition.

did you torque down the fuel rail to specs?? not torquing them down correctly could mess up how much fuel the injectors are getting and foul things up. That happend to me and as soon as I tightened them down some more, she fired right up and she was whistling like a tea kettle. Sounded just like the symptoms you mentioned and would not start or even idle. You could also try pulling the little fuel plug in the trunk to see if it depressurizes the fuel system. It should start, run, idle and then die out releasing pressure in the fuel lines. plug it back in and pressurize and turn the key on and listen for the pressure to kick back in.. might take a few tries. Turn it on but do not start.. then crank it and let her run if she starts. if she does, then it was a fuel system problem, if not than I'd re-check the tune or re-tune it and make sure all the lines are okay. Ruling out the fuel system first helped me out in starting mine when it did the same thing yours did.. hope it helps. Also check how the MAF housing is positioned, should be at 7:00 o'clock if you're going by vortechs guidelines or 10 o'clock, depends on your tuner...

No, dont.
They are prone to breakage and if one or two snaps off,
you have now got bigger problems than before.
Sounds like the tune(r) did not get the tune right....
What does your A/F ratio guage read?

db, it was pretty obvious to me that he already knew the tune
wasn't right (by reading and comprehending his post). my suggestion
was for finding out why the car wasn't starting. while your post is
fair and accurate, it does not help him get the car started and to
me that was the goal.

if he can't even pull a plug (because of fear of breaking one) to help
diagnose a hard starting issue, he shouldn't be supercharging it imo.

I will try the plugs tommrow .. wont hurt.. .

As for the tune it was fine for 2 days until this morning when i tried turning it on..

Thanks for the advice guys..


Any idea why the smoke is only coming out of one exhaust

stealth GT - kind of smelled like fuel... idkkk i hope its something like this and not seirious

howarmat

lmao that is what i was thinking to

need to check spark plugs tommrow

i hope i didnt flood the engine

Pony, the point about the plugs breaking is a valid one,
so pulling one could actually be a little risky. if those are
the original plugs you may want to follow the TSB before
just putting a wrench on it.

any mustang specific TSBs? i only found an f150 a DIY would be helpful but couldnt find any

anyone else have any extra ideas why this is happening?
