2007_Shelby_GT Posted April 29, 2015 Report Share Posted April 29, 2015 Being the lazy type, on a recent trip to the hills, I tossed my spare tire into the trunk, something I've done numerous times in the past with no issues, till now! I stopped for fuel, and when I returned to the interstate, I naturally romped on it. When I backed off, and then accelerated to crusing speed, the car backfired and stuttered like crazy! As it turned out, I got bad fuel, and two GT500s with me did too, but when their issues cleared up and mine didn't, I had to find a different cause. One of the guys suggested fuel pump, and low and behold, that's what it was! The reason? When I romped on it, the spare tire collapsed the floor just enough so that it rested on one of the two fuel control modules and associated wiring in the spare tire well. This caused one of the pumps to stop working, only letting the car run up to about 75 mph, and NO hard acceleration! Lesson learned, put the spare where it belongs, push it off to the side of the trunk, or beef up the floor! This is good info for those that have GT500s or those, like me, that have GT500 dual fuel pumps! Sam Quote Link to comment Share on other sites More sharing options...

HARALD KELLEY Posted April 30, 2015 Report Share Posted April 30, 2015 Your spare was not in the wheel well or was it? Quote Link to comment Share on other sites More sharing options...
2007_Shelby_GT Posted April 30, 2015 Author Report Share Posted April 30, 2015 Your spare was not in the wheel well or was it? No, it wasn't in the well where it should have been! (I've read one case where the wheel shifted IN the well and caused the exact same issue!) Just something to consider if you get lazy like me!
