Meth Pump Wiring?? EXPERTS NEEDED!!!
I was playing around with some interior LED's and noticed that it would only work when both red and black wires were hooked up.. Okay
I have the Meth Pump with the red wire going into the power source and the black bolted to the chassis
i've always been real unsure that my meth was spraying because the fluid level hasn't changed much at all or enough to notice in a couple weeks.
The black wire from the pump.. did I miss something?? or is there another ground wire??
I'm just unsure if I'm actually spraying or not..
I'm tuned for meth, so I don't want to be punching it if i'm not actually spraying
(more information and pictures added lower, pump is NOT getting power but it's wired correctly from my assessment)

A second look at the wiring diagram.. that black ground wire is supposed to be tapped into the COM.. (from the pump)
It was going from COM to ground.. and black wire from pump to ground..
I took the com off the ground, tapped it into the black wire from the pump, and left the ground on the chassis..
I assume this is correct..
I unfortunately didn't do the whole relay and electrical wiring because i was busy mounting the h/e while a buddy of mine was wiring this up...
DO YOUR OWN WORK
the relay is all correct... Fortunately.
The only thing I couldn't verify was if the cable was going to the +12v battery and the +12v ignition.
I assume that is, but i'll double check tomorrow.
I can't test it out until tomorrow considering it's already past my bed time here in Germany
If I'm wrong please somebody let me know

Well lets hope my information is correct...
The wiring is real intimidating at first...
but once you understand the loop, it's not so bad
SInce i wasn't spraying on a tune for meth.. I could just imagine how lucky i've been..

Addition
I tapped the wires to the pump with a LED to see if power is getting to the pump..
Well the LED didn't light up at WOT. The LED was tested to work before hand.
I took some pictures of the connections...
I'm dumb founded right know, i still don't know why it's not working
I'm getting pretty desperate now..
help??
please??

i'm in germany there isn't any METHANOL here.. it's a different kind i guess. . . I got it from a devil's own distributor and it's the blend he uses for his setups..
I relooked at the wiring diagram. it goes from COM to ground.. and black wire on pump to ground
Is this correct???
Do I not have a black wire running from the pump all the way to the COM on the pressure switch??
and for the LED... What wires should I tap the black and red into to verify that power is getting to the pump??????

Before i give up on CSS, the only thing I can think of is that it's not connected to the correct ignition wire...
everything is EXACTLY as the diagram shows on the above mentioned link
either that or my grounds are bad..

I'm not expert but from what I've seen the wiring is quite simple.
Power and Ground to switch.
Signal (Power) off switch to pump (to activate it)
Ground the pump.
Every Meth kit I have seen is wired similar to this, yours just has a relay as well.
Instructions seem quite simple, I noticed there is a note there "refer to pin # and not wire colour" for the relay. Perhaps you should check into that to make sure you have the right wires going to the right pins.
Check your connections, crimp connectors suck....should probably go back and solder and heat shrink those connections or they will give you problems later on (esspecially the ones in the engine bay).
Also, your pump SHOULD NEVER be mounted above the tank, I would fix that. Its says the same thing right in the instructions.
Good luck!

Tonight I'll take apart all of the wiring and re connect everything.. Make sure my grounds are good and all of that..
As far as setting up an LED to verify power is getting to the pump.. What would that entail?
I have the red from the LED tapped going to the pump, and the black wire on the LED to the ground.. Is that all that would be required??
For the relay, everything is connected to the correct corresponding pin, i checked that a few times already. It has a solid connection the battery with the fuse, and the ignition (i think it's the ignition wire) is tapped in accordance with devil's own's diagram.
any further help is much appreciated.

Yes, for the LED if you wire it into the power wire feeding the pump and ground, then everytime the pump turns on it should light up.
Do you have a voltage tester? Makes diagnosing problems like this much easier.
Any wire that has 12v when the ignition is on will work....it would be easy to test if your wire is hot when the ignition is on with a voltage gauge or a test light.
Bascially like you said, go over all the wiring again...double check everything and go from there.

Further testing..
Used the LED I have to make sure the power is where it should be..
I unplugged the relay and stuck the + wire from the LED into each of the connectors on the relay, the negative went to the ground.
On the +12v battery source it works, there's power
+12v ignition, it works!
Pump in - no power.
From the pressure switch out, no power.
okay
so I figure it's not going to send power unless i'm boosting..
So I took the LED tapped it into the positive wire coming from the pump, and I connected a wire to the pump's ground..
Took the car out, boosted.. No light on the LED..
So where I am at is here..
1. The pump has a bad ground (unlikely)
2. The air going to the Pressure switch is not generating a electrical signal. (it's connected EXACTLY the way it should) from the bypass valve, it's tapped with a T connector.
The ground for the pressure switch was tested and it works..
I wish I could test the pressure switch connection to the relay while boosting, but that's easier said than done.
Now I don't know what to do next...

Get a buddy, unplug the vacuum line going to the pressure switch, turn the regulator down on your air compressor to 10-15psi (obviously higher than the turn on pressure you set), jam the end in the line going to the switch with the ignition on (engine off) and see what happens.
Thats the only real way to test it while "boosting". If its working properly that should kick the pump on.
Probably a good idea to remove the nozzle from the pipe so that you don't flood it with meth and water if it does kick on.
Might be a bit easier to trouble shoot that way.

What pressure is the pump set to come on at? Can you set it to come on at like 1psi?
If you can, just blow into the tube...should easily be able to create 1psi with just using your lungs.

it's set at 2 psi..
It's like i'm blowing into a tube that's clogged, there's no flow of air through it.
the tube obviously isn't clogged, but it must be at the pressure switch end or something around there... maybe i have to loosen something?? I have no idea.

Ya you shouldn't be able to blow through the line, its sealed at the switch, thats how it keeps pressure in the line....totally normal.
You SHOULD be able to make 2psi by blowing in the end.....I'd see if one of your buddies has an air compressor tho and that way you know for sure its getting enough pressure when you are testing to see if the switch is sending power to the relay and then to the pump.
