hey i decided to install one of those switches to my fuel pump for added security. i hooked it up and then put the switch to "on". i started the car. i then switched it to "off" to see if it would turn the car off and it did. now it will not turn over. the fuel pump will no longer prime. i obviously messed something up. i can't find a fuel pump fuse or anything.

i took the switch out of the equation and hooked up the original wires. still nothing. all the fuses i check seem ok. i don't know what to do and im freaking out. did i destroy my walbro 255 pump. or the main relay. is there anyway to find out.

ps. i dont have any type of power meter. any help would be much appreciated.

 

I would get a test light or a multimeter just to see if it's still getting power. Let us know.

 

i hook it up to the yellow with the green stripe wire. my switch is a 20 amp. and i used 14 gauge wire. which is alot larger than the fuel pump wire. after closer inspection i found a 7.5 fuse that was blown under the dash. i replaced it and now it is fine. but i would still like to hook the switch up. if i could just find out what the problem is.

i just was radomly looking at fuses and found one. i really don't know what it is becasue its not part of the main panel of fuses under the dash. its just to the right and alittle above that. but it works now after replacing it.

electrical stuff scares me.

 

im thinking it is two things. flipping the switch while the car was running or maybe the gauge wire i used. other than that i don't know. any advice.

 

One of your pins on your switch probably touched ground. Neither of the things you mentioned would blow the fuse.

Instead of a fuel kill (which is beaten down and easily bypassed), why not do a main relay kill like fcm always suggests? Since you're interrupting a ground, there is no chance of you shorting it out and blowing a fuse.
