99 Wrangler won't stay running?
My Hubbby's 99 Wrangler has been having the weirdest problem for the last year. It will work fine & the all of the sudden he goes to start it & it won't start & stay running, unless he keeps his foot on the gas. (this is a manual of course) There is no rhyme or reason as to why this is happening, since the lights & stuff will come on, and it happens at different times (morning, cold, hot, wet, etc) Today he went to start it after work & nothing happened, completely dead. He says he just kept turning the key over & over until it started. He drove it to school, shut it off & it started fine. He thinks its an electrical problem. Does anyone have any ideas what this could be?
Thanks!

It sounds like his starter needs to be replaced. I have a 95 Jeep and it's gone through two starters in 15 years. Being an ex-cop, I'm not particularly hard on starting the car, but mine seems to need it replaced about once every 7-8 years. The part is about $80 to $150 at any auto parts store and you can replace it yourself.
You'll know it's the starter if you turn the key and you don't even get a click from the engine.

If it is turning over it is surely not the starter. Rather I suspect the throttle position sensor. This sensor is located on the throttle body and relays back to the computer how far down you are pressing the gas pedal.
Here is how you can find out. (This is true for any North American built, not Mitsubishi built, Chrysler, Jeep, Dodge, or Plymouth built since 1984 and is fuel injected.) Starting with the key in the off position turn the key to the on position- do not attempt to start the car. Turn the key off, back on, off, then on and leave it. If you have an analog odometer your check engine light will flash a 2 digit code to you. If you odometer is digital, it will display it. Next go to Google and type in 1999 Jeep Wrangler DTC (the code you get) and you will get several websites that will guide you from there.

air, fuel, spark, compression, and exhaust are the 5 things that make an engine work right? so you need to eliminate the things it isn't... like air filter for air, cat for exhaust... then timing, plugs, cap/rotor, wires, or module for ignition fuel pressure or dirty injectors for fuel and lastly, a mechanical problem for compression... bad cam lobe, burned valve... a compression test will answer that just do what's cheap and easy 1st hoping to rule them out before you get to an expensive problem like mechanical or a fuel pump or ignition module
