Less than two weeks ago I had the fuel pump replaced and battery terminals replaced on my 2006 PT Cruiser Touring Edition (not turbo.) I have almost 90,000 miles and have had very few minor issues all these years.
Car stalled while driving, towed it to mechanic, he diagnoses fuel pump failure. So I had him replace fuel pump, and while I was there had battery terminals replaced, since I’ve dealt with some pesky corrosion recently.
I’ve never had electrical problems with this car. So here I am a week after repair, I’m driving and hear an electrical pop in the dash, then the radio turns off and back on within a few seconds. Nothing else happened, I chalk it up to a fluke and keep going. Well it happened again yesterday! Exact same “pop” then radio turns off, comes back on in 2-3 seconds.
Both events happened during the day, so I don’t know yet if my headlights had been on, would this “pop” have affected lights too? Perhaps.
So what I’d like to know is: when the mechanic was replacing the fuel pump and battery terminals, do those repairs involve him messing with wiring at all? Could he have left a grounding wire disconnected? I’ve read a little about the fuel pump relay, but I have not been able to confirm that 2006 PT Cruiser has a fuel pump relay. ? Any other theories on what could be shorting out, creating an electrical “pop”?
