I decided to take the n20 off my car today, and once I had everything buttoned up I tried to start it.
Primed the fuel 3 times, and still nothing. After a few minutes it acted like it was about to start, but no luck.
I am stumped as to what it could be.
Ground wire? sensor? Throw me some ideas, cant work on it tonight as its too dark. The more ideas tonight, better luck I hope to have tomorrow.

 

what kind of system did you have? and what did you unhook to remove?

 

NX wet system. I THINK I have went over everything I unhooked, but there is possibly something and I cant think of it.
Im HOPING that it is just the fuel hasnt filled up the lines yet. It is a possibility, but not to likely.
I had the mallory box, and took that out as well, but plugged the factory coil plug back in. From what I think that is the only part of the ignition I messed with.

 

Did you scan it for codes?

 

Dont have access. Cant get the car started to take it anywhere.
Chevy dealership is literally 500 front feet from my house, but not going to tow it there, lol. Also cant afford it.
Next thing is, I put a fuel pressure gauge on it, that is fine. Checked the ICM and COIL, they checkd out fine.
battery voltage is 11.91 ( mind you I had it unhooked for the 2-3 hours it took to take the kit off the car ) It seems to want to turn over, maybe that is not enough juice? Im waiting for someone to come over and try jumping it. Dont know what else it could be.

Was not having any issues with the car for the last couple of months and the car ran fine up to taking the kit off.

 

Did you cut/splice the nitrous wiring into any of the factory wiring? Did you pop any fuses? Have you confirmed good fuel pressure at the rail?

 

Only checked FP at teh schrader valve. how do i check it at the rail?
Did not splice into anything, the only thing I tapped into was the coil harness wher eI unhooked it and plugged the adaptor in, but that is back to factory now.
Checked the fuses in the dash, all where fine. havent checked under the hood though, will do that now.
Im really stumped. someone is coming over now, going to get a jump. I doubt it is it, but need to rule it out.

It acts strong enough to start, to me, seems like lack of fuel.

 

The Schrader will read the same pressure as the rail, unless you somehow manged to plug up the short length of line between the valve and the rails... and I've never seen that happen.

 

You can try putting your voltmeter on the battery and crank the car. See if the voltage drastically dips.

 

bay area fuses are good

 

Been wanting to do that, but need someone else here to help me. 30 minutes or so should have the cables to jump it and the xtra person, hopefully get it figured out then.
Thnx GTP

 

well no luck.
Put cables on and the volts went up to 13.2 from 11.8. Still exactly the same. While cranking the voltage was 10.8 at lowest.
I dont have a test light or noid light to check stuff, any other suggestions?

 

Car is fixed, ..............sorta.
Hooked the Mallory back up and the car started right up.

We found this out when we checked for spark and it was really weak. So that gave us the idea of plugging the Mallory back up.
What does this mean? Is the coil bad?

 

Means you pissed off the car by pulling the N2O off and now it's ****ing with you

Also take the coil to the local autozone and the will check it to see if its working
