97 Jimmy just stopped running and won't start?

[974x4red]

Okay so last month I wad havin a little fun in my Jimmy testing out the 4wheel drive and the temperature Gage went up a little nothing too hot but after words it was real bogged down so I pulled in a gas station I thought I got shit in the airbox but it was clean, then I go to leave and it won't start. After letting it sit for a min it started back up and still was bogged down and real laggy them a mile down the road making a left turn she died and wouldn't start at all. Took it home replaced the fuel pump cause I thought it might be clogged but still turns it over just won't fire up... I don't even know where to start any ideas??
Any help is appreciate thanks

Inspect your crack shaft sensor for bad wire leads or any signs of damages from mud and water corrosion. Start with that and keep us posted, the crank shaft sensor is located at the passenger side by the crank shaft pulley.

Good luck and keep us posted.

Ok so I changed the crank sensor which restored the spark but it's still not getting gas. The lines are pressurized correctly but just not getting fuel to the Cylinders to fire. If I poor gas into throttle body it'll fire for a second but then dies....

If you have 62-65 PSI of fuel pressure on your shredder valve then your pump is good. Anything less then that will not activate your injectors to run, post back what your fuel pressure is and we can go from there.

Yes there is a crank sensor but before you go changing parts and sensor's check for DTC codes. You have a ODBI system and you can pull your own codes. But most likely it's going to be your ICM, but you can ave that checked before buy a new one.

Auto Zone and Parts Source can check your ICM for you before you send all that money on a new and you still have the same issues. Oh start with the simple and check all your fuses.
