Oh yay, another problem with my truck. <br><br>I'm driving home today and my truck starts hesitating REAL bad on the Interstate. I turn the comp off, still bucking when I hit the pedal. Come home, I smell either burning rubber or something similair. Not like tires, but something else. SO, I go around the block again, it gets REAL bad. Come home, stinks like crazy. This is while the comp is off. I can't really tell where the smell is coming from, but my first thought is that it's coming from underneath and not the engine compartment. Don't know for sure if that's the case, because I did smell it some when I opened the hood, but whatever it is, it can't be good. I don't know if it's a pump, tranny, or something else, but it's beginning to buck real bad. When looking at the rpms, I don't see a real drop, but it's real hard to tell. That smell though worries me. Anyone have any ideas?? I would be glad to fill you in on details if you ask as well. I'm sure I'm not thinking of everything right now. <br><br>truck has 101k miles. :

 

Put on the fuel pressure gauge. PSI at idle= 0-3. WOT= -5

I guess we know what the problem was.

 

I hope not as well. The smell was coming from the lift pump for sure. I couldn't smell anything from the injection pump and the lift pump was intermittent. It seemed when it cooled down, it would work but when it started to warm up, it would die. The truck has been running fine under WOT until today so I'm sure it was gradually dying, and dumped totally today. If I fried the injector pump, then so be it I guess. You wanna play, you gotta pay. Fuel pressure gauge is coming.

 

Wide Open Throttle...
