methanol injection broken AGAIN

chevy1500z71 · 03-28-2008

alright so from day one i had nothign but problems but then we finaly got it taken care of and all was great for a few months and now all of the suden it doestn want to work, the power light comes on but it wont spray under boost. all the wires are good, map sensor conected, the only thing left i guess is to check the internals of the controler, the map sensor should be fine as it is practicly new... any ideas? o and yes grounds are good pump has power and ground, all if perfect, one day it just refused to spray but the controler power light is still always on.

its a progressive kit btw

nothing? i realy wish i would have spent the extra 100$ and got a snow performance kit, i never hear of anyone having this much trouble with the snow performance kits...

somebody please help with this, i blew 300$ on this crap and it never seems to work! am i the only one who has this much trouble with it? i have installed everything properly and i took my time and made sure everything was rite, i think the controller is no good.

Can you hear the pump running? If you let the fluid run dry ti will lose its prime and will not reprime unless you disconnect the check valve first.

Not sure if the colors are the same on the newer kits, but, for my kit the blue wire from the controller goes to the pump +12V. I can unplug the controller and apply power to the blue wire from the battery and force the pump to run. I do this when I need to reprime or when I'm flow testing a new size nozzle.

You might try this just to see if it's the controller or the pump.

the pump does not kick nor does the light light up, it does nothing but the power light is on.

i used a volt meter and i got 1.22v off of the grey and 1.25 off of the green, and inside the truck i get .5v on the blue that goes to the pump and 1.11 off of the grey that goes to the map?

does that sound close to right or way off?

Sorry, I misread.

Since it was working, and nothing has changed, then perhaps you are correct and your controller is bad. I hope that's not the case and it's something simple and cheap.

i took apart the controler and none of the wires are loose, i primed the pump to see if it works and it does, its just not geting a signal from the controler...

prety frustrating becasue i was going to race it tonight

Have you tried touching the grey wire to the green to see if you get activation. that is a 5v and should run the system at full that is basically how you can test your connections. If the unit is not picking up voltage then it will not activate.

If your getting 1.22 v off the grey wire then the unit has been damaged. It should read 5v +-5% . The green wire of the controller is an input It can't produce voltage. I would assume are getting the voltage from the map sensors green wire. please email support@alcohol-injection.com for a warranty paperwork.

thats odd, i havnt done anything to damage the controler, everything was perfect and then it just all of the sudden stoped spraying...

so what will i get a new controller through my warranty?
