1999 Jeep Cherokee my Jeep wan start

Hi:
If the fuel pump could run but not produce enough pressure. If the check engine light is on, something tells me there is a sensor problem. Have you checked to see if you are getting spark? Also, here is a how to video to watch. It explains how to check for fuel pressure.

Keep in mind, if the check engine light is on, there is a code in the computer that will tell you the problem, but you will need a scanner to check what the code is. Most parts stores will scan for free, but since the vehicle doesn't run, you may need to see if you can rent one.

Let me know what you find.
