Checked the idle control valve next to the throttle position sensor? Remove it and spray the passageway out with carb cleaner, then clean off the valve end (don't turn it while cleaning) Don't loose the "o" ring on the part either.
Before doing that though make sure all the vacuum hoses are attached and not cracked or broken.
Other than that, you may have a bad throttle position sensor or map sensor. Check (test) them before buying...they are expensive and you don't want to buy stuff you didn't need! You have the advantage here. I can't see the car. You can, and need to test!!!

Wont hold idle will start with foot depressing gas pedal will run with foot on gas but stalls when foot removed


Check and clean Idle air control valve. Make sure its responding to signal as well. Also make sure ther are no vacuum hoses disconnected. This may not be a "cure" but it's a good place to start.

1998 jeep cherokee 4.0 it cranks but does not start tride puting gas or starter fluid and still it doesnt start I think Im not getting any spark


Your dealership can read the codes entered into your car's computer every time it malfunctions. Same problem as yours, however, also gets worse, back up lights won't work, sticks in park (in the gas stationing) (very embarrassing), will only run with foot on gas, etc. It was the "neutral safety switch". $500 fix but runs and starts perfectly all the time.

Hi, you should start by checking all your fuses,if they are all good ,check fuel pump relay, if this is ok , check fuel filter, if filteris good ,you should run a fuel presure text, this will determine if your fuel pump is ok, good luck.......
