Had a bad jump start that fried a few things a few months ago. Replaced battery and alternator, so those are both new, and replaced the 100 amp mega fuse and A/C relays. The truck started and ran for several weeks, but then one day turned the key and it did absolutely nothing...also, absolutely NO lights on the dash display except for the check engine light. Had a friend test with scanner and it can't link with computer. Got a new programmed PCM, installed it, and same problem. I think it's a relay, but no idea which one.
Also, we've noticed that now the brand new battery goes dead quickly, like, in about 3 weeks. I just think that's awfully quick for a new battery to go totally dead. It's as if something is stuck ON and draining it. Any help would be greatly appreciated!

Hello I was having trouble coming to a stop and my engine wants to stall so I finally came to replace the throttle body and did a tune up while under the hood with spark plug and ignition coil replacement and oil change. When I finished I come to turn the key and no start. I continue to replace the fuel pump, Mass, map sensors and crank position sensor. With my finally replace was the fuel injectors. After following the repair Manuel. Its turns on for a second and doesn’t stay on. I did a compression test and it passed with 170 psi every cylinder when I was driving lasted there was some loud noise coming from the engine but they went away. I check all the fuses and nothing blown

When driving along an inclined unpaved road without accelerating, and even sometimes braking a bit, the van suddenly stalled. I have noticed it has something to do with the lamps as, when the vehicle is about to stall, lamps fade.

All off a sudden ac stopped working an blowing hot air the Freon is full plenty of pressure but compressor won't kick on I checked the pressure valve sensor on the line jumped the plug with a wire an compressor still doesn't work
