Zex blackout kit troubleshoot

**bigbucksnort** · 08-17-2015, 08:45 PM

I have installed the zex blackout wet kit and it is not spraying. Acts like the NMU isn't opening. Key on, the light on the NMU is green, when you press the gas pedal down the light flashes green, but you never hear a click of it actually opening. Definitely have gas to NMU because it's purging fine. I've tried resetting the nmu's memory, still no gas. I'll call them tomorrow for tech support, but thought I'd throw it out there in case someone on here has had the same problem.

So just for the record-

I dropped the NMU off at Comp Cams the other day for them to test it out. Sure enough, it's faulty. They are replacing the part free of charge (unfortunately they have no black ones and I'll have to live with the Zex purple.)

So, come to find out the NMU was faulty. Took it back to comp cams, they game me a new one.

I put the new one on today and it's still doing the same exact thing.

I'm 99% sure I'm tapped into the correct tps wire. Key on at rest it shows .6 volts, open the throttle up and it gives about 4.6. The other two wires will not change when the throttle is messed with....

Called Zex tech support and didn't really get much help. He said it's either another faulty unit or something really simple is messed up. Well no $hit.

I'm at a loss. Not sure what to do now.
