ive recently had the dash apart to fix the defrost diverter. i hooked up my camper and a few mile down the road i could smell electric burning. when i got home i noticed the fuse for the door locks was blown. iv since had the dash back apart and replaced the door lock relay. worked fine for a week until i hooked up my camper again. which blew the fuse within 15 miles. ive disconnected the brake controller the cig. lighter ports. and the fuse blows as soon as i put one in (gone as far as 30a)

power steering box, power steering pump and hydro vac brake booster were all replaced and the whole system was bled out

I changed my full filter and full pump in my 1997 Chevy 3500 silvarodo P/U 7.4Lt and was running 10-18 psi so I put in a new full reg and it stayed at 10-18 Psi. so I picked up a Haynes manual that shows that 10-18PSI is the rang for a V6. Autozone gave me the rong Pump. So now I have instaled the E3270N pump and it is reading 20-30 PSI. There was only one clamp in the pump kit but the hose fit snug to the pump can I be loosing the pressure from the gas cap? 25 PSI

I put in a new full pump and it starts right up idles smooth till i give it gas then it sputters till it warms up and it runs fine but it sputter puling away from the stop sign then smoths out and runs fine till the next stop sign. any idas??

I changed out the gass fillter and that seemd to hellp.

Replaced the switch have followed the wires from cab to lights running down the frame cannot find any shorts that way. Any ideas on where to go now

Have power to & fuse(Fuse is good) but none to connector. This fan is for the A/C condenser. Can't locate the relay. Any ideas where it might be. It's not in the fuse/relay center. A/c is cooling fine. This fan should be running when the truck is not moving and the a/c is on.
