Welcome to teh site my name is Kevin
go back and chk all the fuses and for god sake dont let him monkey with the fan any more replace the relay for the fan for 80 bucks and U wont have this kinda issue again.
The fuses under the driver sai dash there are a few there.
Which wire was he poking ne way?
why would he mess with the fuel pump wire for the fan?
fuse 12 10 amp is for the fuel pump under the driver side dash
that wire is for the control side of the fuel pump. the power supply comes from teh IGN switch to a fuse 12 10 amp under the driver side dash then to the fuel pump and also goes to the PCM. so my susgestion is to trace it from teh ign switch to the fuse then from teh fuse to the fuel pump relay then to the pcm see if u have a brunt up wire ,blown fuse or burnt up ign switch connector.
tell me again u have checked the fuses under the hood and dash? how are u looking at them with a test light or pulling them out?
U said it runs when u add power to the wire that wire is just power to the fuel pump relay and IGN switch feed to the pcm if they had gotten damaged from it it would not run regardless if u add power to it or not. It is also part of the ASD control.
Here is the down and dirty U dont have power on a wire that should have power when u turn the ign switch on start at the switch with a test light or volt meter and back prob see if U have power at the ign switch on the same orange and blue wire
power for it comes from a 40 amp fuse under the hood
there is a simple explnation for this I just need to know things are being done right over there
no cold air blowing out when ac is on but low pressure
