Driving along then Jeep seems like it not getting gas, then it takes off. Started backfiring. Blew hole in muffler. Put on new new muffler & it blew a hiole in that one also. Replaced crankshaft sensor but still doing same thing. What's wrong??

Cars are like that. I think they like driving people crazy. I\'ve been driven crazy by my Sentra for three months now. Has the fuel pressure been checked? I wonder if your fuel pressure regulator has failed (the diaphragm inside will rupture and suck extra gas in through the vacuum hose attached to the regulator-could be the cause of backfiring). Something to check, anyway.
It's not possible to pinpoint, with just online info, what is causing the backfire, but if it blew your muffler open, the engine is definitely dumping raw fuel into the exhaust. Look into what can cause excessive fuel to be dumped into the exhaust and you may find the cause of your problem.
What a funny set of events.Of course the tail pipe is clear(you would have checked that)The only other thing it might be is the cat/converter is blocked.New muffler is allowing a heap of air through and it suddenly clears and the bang.They do block up so it may be worth getting it checked.Hope this helps
does your jeep run rough? idle is real low? and when you are driving and push the gas hard it doesnt want to move? if so it is most likely the mass air flow sensor. i had to replace that 2 or 3 times on my 1999 jeep cherokee
since its a 1997 your jeep has EFI, electronic fuel injection. The most probable reason for your troubles would be the injectors or a problem with the computer controling them, not allowing enough gas to be pushed into the cylinder causing stalling or lack of power, also too much gas iin the cylinder can lead to back firing and stalling. This would also explain the reason it takes so long to start back up some times, all the excess gas in the cylinder is flooding the motor and u have to wait till the gas disipates till the engine will turn over.
Aaron, I had the same problem. It is the most expensive part of course the computer. I replaced everything as well till I replaced it. They are remanufactured and have had problems with them as well. I am on my third one now at 200k miles. Oh and by the way it does not show up on the diagnostic check. Good luck
hi if you can get it to do it so you can pick the bonnet up and listen check out alternator power steering pump [if fitted] water pumps any thing driven by your belts check the belt for signs of slipping if the noise is presnt you can take your alternator belt of [temparary] run engine see if noise dissapears it sounds like a small bearing yates210456
