so i am in the process of changing a bunch of front end parts on my jeep. i hadn't started it in a few days so i started it and let it run for a few minutes. it started up great with no problems.

i then decided to finally fix all of the dangling wires underneath of my dash. (drivers side) so i took off the bottom panel and zip tied all of the wires up and put it back together. i then tried to start it again and all it will do is crank. it has fuel pressure, i checked that. my guess is something isn't getting a good connection under the dash where the security system is, any way to bypass this?

it started and ran great before i zip tied up the wires.. i'm stumped.

its a 90, 4.0.
any help would be appreciated.
thanks

 

did you check for blown fuses? are you smelling fuel as you crank it rember fuel pressure doesn't equal injector pulse, check for spark if you have spark then its a fuel problem if not obviously its a spark issue follow the kiss principle keep it simple stupid most electrical problems are really simple.

 

3 things to check for staring, fuel and air, compression, and spark

 

Rather than bypass the "security system', consider removal. If it ran fine before you noodled with the wiring, I'd bet the farm on an underdash wiring issue. Un-zip everything, let it drop down and carefully go through it, making sure everything is properly connected before you button it up again.
