NOT WANTING TO RUN.

1999 Jeep Grand Cherokee • 16,000 miles

I have a 1999 Jeep Grand Cherokee Lerado Straight 6. I can start it and drive about 3 blocks and then it looses all power. No matter how much gas you give it won't go. You can hear like a back fire through the air filter area. It does it with no signs. No check engine light had came on. I have replaced the fuel pump and socks, fuel filter, crankshaft position sensor, changed plugs, and catalatic convertor. Nothing has worked. Please help

Scan for codesan dcheck fuel pressure first. Check your auto shutdown relay.
