Need some help, i have a 87 camaro, used to have 305 in it but now as a 350, i bought it a week ago and now it doesnt start, that problem is that there is pwr. the headlights, and accesseries work and that is about it. i get 12 volts out of them on the fuse panel. the battery is good, it has some servo thing on it for the OEM that i am not familar with it connect to the brake wiring by the pedal and the ign on the fuse box. i was messing around with my fan wire( it has an electric fan) and moving it around when i must of shorted some thing and i got pwr, i turned the key and it fired right up. let it idel for about 10 minutes then when i got ready to move it, by pressing the brake and shifting it into drive it died, and then i couldnt restart it. Any suggestions
thanks

 

Did the car die when you pressed the brake, or when you shifted in to drive?

 

when shifting in to drive, the car engaged and then it lost pwr
