Im having this problem with meth filling my intercooler up randomly when the car is off... the whole system has been rewired after it killed pump #1, then after it killed pump #2 i changed relay. so now im on pump #3 and its still doing it. (by killing pumps they still turn on just dont pump any meth)
it only does it when the car is off. its not the way i have the system wired because i had the same wiring for over a year with no problem and its been all rewired. plus it only does it randomly
its just the basic kit (pressure switch, relay) after changing relay im stumped. power is wired into fuse box in engine bay.. ignition is wired into fuse box in the car... other wire goes to pressure switch witch is grounded next to the tip sensor where the battery ground goes. last wire goes to pump and the pump is grounded in the trunk where the tails lights are grounded. and i have a check valve in the line about a foot from the nozzle
anyone have this problem or any idea?

There is 100% certaintly that your system is wired wrong. The fact is, if its connected to the switched ignition with or without the relay, it would not turn on with the car off. If it is wired 100% correct, the problem is your car and you have big problems.
Here is what I recommend.
#1 dump the relay.
#2 take the boost switch and give the COM port your switched ignition (NOT BATTERY).
#3 take the NO port (the middle port) and connect to the red pump wire.
#4 ground the other pump wire.
its wired the exact same as it was last year with no problems, also the exact same way in 2 of my friends cars with no problems, just started doing it out of nowhere. and does it randomly.
i will try it that way will there be enough power coming from just an ignition source?. but i do need to figure out why its doing this out of nowhere.
could it be the pressure switch grounding and causing the pump to randomly turn on? what could cause the pump to turn on?

you are saying your car is OFF and the system starts randomly.
Either its wired wrong OR your vehicle is malfunctioning. If you have it wired to the switched ignition, that wire ONLY gets hot when the key to the car is turned on.
If you have it wired to the switched ignition, the pressure switch can malfunction all day long and it will not turn on unless the key to the car is on.
Your car is wired wrong. Most likely your boost switch has gone bad, however your system is wired to the battery as well. it needs to be wired to the switched ignition.
I dont want to sound like a broken record, but I dont want you to lose an engine either.

it is wired to switch ignition..
this is how its wired up
on the relay
85 goes to No3 on boost switch (com is grounded)
87 is the pump (black pump wire is grounded)
30/51 is power coming from fuse box in the engine bay, its hooked up to one of the 10mm nuts
86 is coming from an ignition source in the cars (fuse box) and that also has my boost box/wideband hooked up to it, it was also tested with a meter (there is also a on/offswitch in the line)
the car was wired this way a year ago with no problems thats why i dont get why its doing it now
you say the boost switch could be going on me? it still comes on at 11psi (i have a led light that comes on)
You have a big problem somewhere. If your system is wired to the switched ignition, even if the boost switch is bad, it would not start your car.
Maybe your relay is fried.
I would re-wire it the way I said in the earlier post. Just skip the relay. Its how our cool150 kits are done, it works fine. That will eliminate or confirm the relay is the problem.

well i unhooked the power to my meth kit till i could rewire it and today i stared the car and the whole tank of meth was in the intercooler....? so now im lost??? so its defeantly not the way it was wired up
sounds like your check valve is bad. with a bad check valve (or solenoid if you're running that) your meth tank will drain until the water level is even with your nozzle. if you have a trunk mount and your nozzle is down by the intercooler your whole tank will basically leak out past your check valve into your IC
sschung is correct. I was going to reply today but with the flooding its still a mess here and been very busy.
If your checkvalve is pre 2007, it would have swolen and leak. When you said the system is turning on, it through me off. The fact is your system is NOT turning on, its just leaking past the swoolen seal on the checkvalve.
well that sucks how about a hook up on a check valve then :P
so why would it kill the meth pump i had 2 cooling mist pumps die after it filled my intercooler?
