Ok we got the STS installed and we where trying to check the buzzer and by just turning the key on with out starting the truck by connecting the pressure switch at the pump with a jumper cable. When we did this we blew tons of fuses the fuel pump fuse blew as we as many others. We have replaced all of them but we have not tried the buzzer (which did not work) again the oil pump is working but now I am throwing a code it is P1518 which is
P1518 Intake Manifold Runner Control (Stuck Open)
The truck is running and I drove it about a mile to get home and it ran fine my ? is what did we do wrong to blow tons of fuses and why do you think my truck is throwing this code.

Is it safe to drive 7 hours because I have to get back to school Sunday night and go see Allen some time in the next week to get a tune?
