Not to toot my own horn, but I don't often run up against a problem that I don't know what it is.
But right now, Im square in the middle of one.
It's a 200 w/ 1100 and DSII running off of GM a module.
Problem is, it won't run. Its a little hard to start, and when it does it kicks over, idles down, and dies.
I've gone through the ignition with a fine toothed comb (O-scope, function generator, tested it all) and it all works fine. I replaced it all any way too, with no change.
So I thought it must be fuel, but It won't run on the idle OR main circuit. What's worse, is it will die while I am pumping the throttle and I can SEE gas squirting out of the ACC pump as well as out of the main circuit.
And it will still die. I figured out that when it is dying, if I spray a shot of carb cleaner down it, it will rev back up again for a second and I can kinda keep it alive that way - which really makes me think it's a fuel problem except I can see the fuel flowing in there.
It was working fine, but in the process of doing this turbo install, I had it idling a lot. I was revving it up with everything attached to make sure it all worked, and when I let it back down to idle - it died. Hasn't run right since.
So I am sorta stumped. I will probably try another carb today, but I am skeptical of that being it. I also did a comp check to make sure I didn't toast a valve or something, except it came back 150-160 across the board.
So I am really confused.
I swapped plugs, too. No change.
Possible I wasted the Pv in the 1100? The plugs I pulled our were BLACK with soot, but I had also been idling it a lot so tat doesn't seem too strange.
And if the PV were wasted and dumping fuel, I doubt that spraying carb cleaner would help it kick back up. - It's just more fuel.
Anyway, suggestions are welcome. I'm an EFI guy, dammit.
