I have an 04 Chrysler Pacifica that has a fuel issue of when it gets to 1/2 tank fuel gauge drops down to empty and stalls out when coming to a stop. Any thoughts?? I also recently had car in shop for blower motor to be replaced and while in there I mentioned a harsh shift and they did an upgrade on PCM, and charged me on top of that. Ever since then when I try to start car I have to wait for ticking noise to stop that is coming from the fuse box under hood, then once that stops car starts right up. I did find out that when two relays were taken out, which are the fuel pump relay and I think ASD relay, the ticking noise stopped. ????????
