No fuel pressure, pump was not running. Banged bottom of tank and pump tried to go but sounded weak kinda chugged slow then took off. So... we changed the pump and assembly.
Now the new pump won't come on. We've cycled key on/off tried cranking the engine. Etc. Also the fuel gauge is pointing staight down way past empty, needle is actually hitting the edge of the cluster.
We switched the fuel pump relay with a lot her one. What could cause this?
It was recently towed twice by the same company to their yard and then a month later to my home with no keys on a flatbed. This is an AWD all the time 2002 gmc Denali. We had to have a new cylinder and key made. We went to start it and put it in gear the vehicle will not go into ANY gear?? Please help they swear they did not damage the drive train...
I started the car and I heard this hissing in the back and saw smoke like if it came from the tail pipe but then, next day my ac blew hot air ? and my car after charging all night is dead

I have a knocking noise at take off and as slowing down. It sounds like the rear end to me, but wanted to see if anyone had any other ideas (trans or transfer case).
I recently went to dealer to pick up a door lock actuator for the passenger side front door. It had only two electrical connections on it instead of three that is on my vehicle. The third electrical connector is for a plunger is what I was told and that he wasn't sure if it was needed. Does anyone actually know if it is needed or can I use the actuator with 2 electrical connections? Also what is the purpose of the plunger?
