I've had this truck almost 5 years. It has a tick over 200k miles. I've taken great care of it and it drives like a machine. BUT here over the last 2 months it started stalling out when coming to a stop or slowing down to make a turn. Not always, but randomly. It usually starts right back up, but twice now it won't. Today I gave it a shot of starter fluid after fighting with it for 25 mins. and it took right off. The dealer can't find anything wrong with it as it hasn't acted up with them. No codes. I cleaned the throttle body and replaced the fuel injection module(200 bucks). Neither has solved the issue. Also have put injector cleaner in at fill-up. Hoping to find someone with some answers. I'm working pretty remote up in the mountains at the moment and having a truck I can't rely on is scary. Thanks!

 

So now my truck won't start at all. As stated above, I've replaced the fuel pump driver module, cleaned the throttle body, cleaned the MAF sensor, and replaced the fuel filter. I did get it to start today after another shot of starter fluid. After it started, it ran fine. I shut it off and started it a few more times. One or two times it started right up like brand new. The next time it struggled but did turn over, the next time.....no start at all. Back to square one. It turns over strong as many times as I try, so I know it's not the starter or the battery. I have to believe that the stalling and non-starting issues are related, but neither I nor the dealer can figure this out. Is there any help or suggestions out there? Can't use the truck at the moment and it hurts.
