K I just did that for about a half an hour and no luck, still stalling.

you sure you have no vac leak?

Not sure, can't get it running long enough to check by myself.

Turns out the iac was dirty,I cleaned it and not it's drivable but it's stumbling a bit.

Its stumbling a bit so i did a DTC scan and I got these for codes:
P0303 - Cylinder 3 Misfire Detected
[] P0452 - Fuel Tank Pressure Sensor Circuit Low Voltage (SES) (Pending) (Old) (History) (Current) (Immature)
[] P0481 - Cooling Fan Relay 2 Control Circuit (SES) (Pending) (History) (Current) (Immature)
[] P0102 - Mass Air Flow (MAF) Sensor Circuit Low Frequency (Immature)
[] P0243 - Turbocharger Wastegate Solenoid 1 (History) (Immature)
[] P0300 - Engine Misfire Detected (SES) (Pending) (History) (Current) (Immature)
[] P0463 - Fuel Level Sensor Circuit High Voltage (Pending) (History) (Current) (Immature)
[] P0656 - Fuel Level Output Circuit Malfunction (Pending) (History) (Immature)

I just deleted the p0243 code and will have to look for the source of the cylinder #3 missfire but what about the rest? Should I delete them codes as well? other than the maf, I just sprayed some carb cleaner so I will take it back out and re clean to see what it does for that code.

I went out and verified a spark at te number three coil. And I also verified there's power to both wire at the injector and are pulsing when running. So I pulled the plug and man would I looooove to put a steel toe boot to the balls of the f'er who came up with that design. Well the plug was blacker than tobeys a$$, not sure if that's because of the short firing time when I checked for spark and then again for about 30 secs checking the injector. Just thinking as I'm typing this I guess I should check for spark by grounding the plug attached to the wire incase there's something wrong with the wire. Any idears?

I removed the #3 spark plug an'd I guess I'll never know if that was the problem as I dropped thesum*****. I was trying to put the new one in and was having a problem getting it in when I noticed the oil dipstick tube was aff to the side but in the way. So I had to pull that out and got the plug and metal heat shield back in. I put an ear plug in the oil tube hole for the time being and fired it up and clears the codes that haven't come back. I was just thinking, is it possible that the metal dipstick tube that was obviously up against the metal heat shield causing the missfire?

not sure what the problem is but for a minute there it sounded like a fuel issue. Sitting for a while could cause the car some laziness and or stale fluids like the FUEL. Try a new fuel filter and some fuel injector cleaner/stabilizer. May help, may not but im sure your fuel system wouldn't mind it. I use chevron Techron but lately I've been using Royal Purple Max fuel clean in my cars and others. here it is[IMG][/IMG]

It might have been the spark plug or it was grounding out. Whatever it was its gone now. The fuel was completely drained when I put the new fuel pump in. I also put in new fuel filter also. I will put in injector cleaner just an added insurance.

So its running now...GREAT. Keep up the maintenance on these 3800s and they'll last forever.
