I just did a head swap and cleaned up the wiring on my nitrous system. Got eveything back together and the car runs great without the nitrous system fuel line hooked to the fuel rail. When I connect the line to the fuel rail, the car will not start and almost floods immediatly. Im guessing either it is wired open or the silonoid is stuck open and needs rebuilt. Any advise would be appreciated ??? I have been fighting other problems to get the car running so I havent checked anything yet. Thanks guys

 

Might be stuck open, or you have power to all the time. It doesn't matter which wire is hot and which is ground on the noid itself.

OK, I dont even have anything plugged into a key on hot source yet and it was still flooding. So my guess is that it is stuck open. Do I just order a rebuild kit?

 

Take and unwire the solenoid. Then hook it up and see if it is still leaking buy. If it is the fuel solenoid may have a swollen plunger.

What brand soloenoid is it?

 

Would it still have power if I have the key on hot connector disconnected?

Its Cold Fusion brand. They worked frine before my head swap but I guess its time for new ones or a rebuild.

 

Check to see if your fuel supply is hooked up to the outlet on the solenoid.

 

The inlet and the outlet is hooked up correctly.

 

It might have just seized up....

 

I guess I gotta go through my wiring a check first then rebuild. they need it anyway. Where is the best place to buy the rebuiled kit for both noids ?

 

Did you get some type debri in the solenoid when you did the head swap?

Just a thought...

 

I guess its possible but honestly Im not sure.

 

FYI- A good way to check real quick if the solenoid is energized is to touch the top of it with a screw driver. If its energized the top of the solenoid will be magnetized. Little tricks of the trade....

 

WOW didnt know that !! Thanks

BTW, I wish I was closer so you could do the tuning because I have heard awesome things about you

 

You may have just got some gas cut with methonal causing the plunger to swell. We do not support Coldfusion products however if you want to send it in we will open it up and check it out for you at no cost other than shiping to help you out.

That would be GREAT !!! I really appreciate your help Dave, your awesome

No problem. I am happy to help when I can.

I tihnk I found what is wrong. I had both of the wires on the nitrous noid grounded and probably both wires on the fuel noid hot, if not grounded. Ugh I hate wiring haha

 

speaking of tricks of the trade- open that bitch up yourself. take the nuts off of both solenoids, then take the plastic/ top part off of the fuel one (dunno the component's name but it'll practically fall off)

screw both nuts onto the fuel solenoid plunger and lock them together with 2 seperate wrenches. then stick a wrench on the bottum nut and take the sucker apart (unscrew it). inspect what everything looks like and post the results. not rocket science and as long as you are careful you won't **** anything up.

edit- if you found the problem nevermind...
