what's wrong now?!?!?

[sprayedenali]

ok, so I was just headed to the gas station and on the road from my house I sprayed a 100 shot twice for maybe 5 seconds each. And then when I get to the end of the road and stop the engine shuts off by it's self ad re service srabilitrac and traction control come on... I try and restart it and it's real hesitant. I shut the motor off again then restart it again and it has to turn over a couple times then slowly fires, which has never happened before... Ten when I'm almost to the gas sttion it tries todie while I'm just going down the road. What in the weld is going on now?!?!?!? And it's bit making any weird noises or leaking anything...

[ducky]

fuel pump crapping out?

[CHEVROLADE]

denalis are a pain in the a--,sorry to hear that,hope you get it solved out.

[GasGuzzler]

I wasn't able to answer the phone. You need a scan and fuel pressure gauge to start. Did you get a reduced engine power message? Call OnStar and get the codes.....just don't believe anything else they tell you.

[sprayedenali]

ya, sorry Nathan for bothering you! but when my truck scared the piss out of me about 4 times over 2 miles, i got pretty worried!!

i need alot of things and gauges!!!!!!! im working on getting some of that stuff right now. but no it never went into reduced power or anything like that. now its all gone and the truck is running fine it seems like with no stabilitrac messages or anything, so idk....

also, it kinda seems like after i spray it the next time i start the motor it doesnt want to fire right off, is that normal for using nitrous or is something else going on too?

[Sizzle Chest]

Thats not normal. Did you do any fuel system upgrades or is still stock? I had some similar sounding problems with a walbro255 when I first put it in.

[sprayedenali]

nope, all stock fuel system. but its a wet kit, so that shouldnt really matter, should it???

[GasGuzzler]

It could matter but wouldn't cause that.

I got home at 1:15 or so the other night and that makes it hard to answer the phone at Wal-Mart on Sunday afternoon with the younguns. LOL

Hope it doesn't come back.

You got P1133 and/or P1153 again yet?

[sprayedenali]

nope, they havent come back yet... (fingers crossed)

virgil told me he thought it sounded like it tried to spin when the nitrous hit and the computer freaked out and did all that, is that possible?? i could understand the service traction control and what not coming on, but not the motor dying and not wanting to run...

also, what about it not wanting to start when im using nitrous? could it be one of the solenoids leaking a little into the intake, cause im pretty sure it only does it when i leave the bottle on i between runs

thanks for all your help guys!! maybe eventually ill stop having all these problems!

[GasGuzzler]

Don't leave the bottle on between runs. The only fuel pump problems I've seen on the GMT900 body has been bleed off and/or extended crank problems. It is amazing how one thing will affect another on these newer ones.
