starting issues
 

i have a 1990 jeep cherokee with a 4.0 engine and it won't start.
Details: i have spark and fuel up to the rail it has enough spark to run off of gas pored down the intake. i am dumbfounded and can't figure it out it all happened a short time after my cigarette lighter went out in the jeep not sure if it has anything to do with it but there is no pulse at the injectors now. It used to stay running if i had the key in the start possition when the starter was running but as soon as you turn it to the on position one back from the start possition it would die. Any ideas i have heard about an auto shutdown relay but all my relays were good under the hood and it evens starts off of gas poored under the intake when all the relays are unplugged it's a 1990 jeep cherokee with an ax15 transmission

update
 

oh there is pressure up to the rail

Change your ballest resetor maybe this will work it use to on the older p/u I not sure though but for 2 buck try it .Just a shot in the dark but I remember this happening in my old p/u.

ballest resistor
 

were is this located under the hood is it on driver side and does it have two wires plugged into it?

you are correct. that went on my buddys in the woods haha we actually had to hardwire his fuel pump to his battery to get him home

the fuel pump is kicking on and i have it hardwired around that and it's always had pressure up in the fuel rail but no injector puseing it has fire just no pulse
