Jeep wont start checked connection and fuses

Check the fuse box for the starter relay, and pull out to check pins for corrosion / bad contact. The fact it start on a bump with the key on leads me to suspect the start / crank position of the electrics. Get a knowledgeable person to run through the crank circuit with a meter, also check the condition of earth straps and starter cables. Could be the ignition switch is faulty?

There should be a reset for the fuel tank. It is a safety switch that they have added to stop fires from rearend collisions. Not sure where it is on your vehicle. Look in owners manual or call dealership.

sounds like dead short some were starat at battery and work back

you may have a bad starter solenoid.using a test light at the starter the light should be lit on the large wire terminal and with someone trying to start the car yhou should have the light on when the key is turned to the start position.it you have a volt meter you should have battery voltage on the large wire and the same on the small wire when the key is in the start position.you can try tapping the starter when someone tries to start the car.if it starts then replace the starter.its the most common problem.

9 times out of 10 it's the realy but check if stater is getting power to crank wire

you have a fuel pump relay . Check to see if the fuel pump is humming when you turn key. check for proper ground for fuel pump. try spraying some carb cleaner into the intake then attempt a start. The engine will run for a few seconds, this will verify spark. corosion at the electrical connections is always a possibility. and lastly can you get the engine running by opening the throttle when starting?

could be a bad connection to battery, starter or even a bad alternator. get them all checked out. if its not any of those then start checking fuses.

Check all wires from battery to starter are connected and clean and tight.If they are then your solinoid is your problem.

check to see if their is any fuses blown or change out the fuel pump relay and also check to see if the ground to the fuel pump is getting a good connection these things should solve your problem.Good luck

this could be a bad fuse, or check all your wire harness's especially the one connected underneath your fuse box and also the fuses
