Got several of those kind of stories from back in my wrench turning days..
Once had a customer drive up in a Honda to the service bay door. The boss stuck his head out and ask me to check out this guys car. Said it was "missing".
I could tell by the sound it was only running on 3 cylinders.
Raised the hood and as I looked down in amazement the guy revved it up to about 3k rpms. There in plain sight was a hole in the block and a rod hanging out.
The guy said he had driven it around 20 miles since it started missing !
Took a while to convince him that it needed a new engine. He just didn't understand that it had blown up even though it was still running.

 

Thanks guys, like I said, time to get another engine. Once I get the original engine out, I'll remove the oil pan to see what the damage is, that should settle it once and for all.

 

My dad made my mother drive the old Studebaker in to the dealer as trade bait, 30 miles with a piston hanging out of the block.

 

Hey guys, changed the engine! Now there is an issue with the wiring. I'm guessing a bad ground, but I would like another opinion. Turn on the AC the car stalls, turn on the rear wipers, car stalls, plus fuel pump is sending error message. None of these issues before engine swap.....any ideas?

 

If you told us what the "error signal" was we might be able to help. Yes, you have a wiring problem; since both switches are next to each other I would start there.

 

Gotta ask - what year, and what vehicle did the replacement engine come out of, and what engine (2.2 or 2.4)?
and what exactly is the fuel pump error message? Saying it is sending an error message doesn't mean much at all.

 

Engine is a 2.2L out of a 2010 Colbalt. Error message is P0230.

 

fyi: p0230 is "Fuel pump RELAY CONTROL circuit" Not much to do with the pump itself.

So now we need to figure out where the common point between the rear wiper switch, the AC switch and the fuel pump relay control circuit is.
The easiest to find is the ground point on the driver side strut tower; something seems to be shorting there.

 

Will update after checking it out, thanks!

 

Well fellas, turns out it was indeed a ground that was disturbed durning engine swap. Replaced with new ground cable and all is now good! Thanks to all of you that offered advise. Have a great weekend.
