Help 1996 jeep motor it's hard to start when warm
So my Jeep when warm or hot is hard to start or won't start whatsoever. Could it be too much pressure and fuel line.? Try troubleshooting it and that's all I can come up with I put my finger on the thing to release pressure and it's very high pressure don't know is sprays forever like good pints comes out of there thank you

Seriously you need a fp gauge to tell what the pressure is.
Not starting when warm is a classic sign of crank or cam sensor. These usually throw a code sooner or later, usually later.

if it was a sensor would it run after i push start it because thats how i get it to go again
I think this might be the sensor on the thermostat housing telling the computer its cold, and give the engine too much gasoline. if its start easy when cold and not starting easy when the engine is varm it could be this sensor. because its starting when you force it.
