may have unplugged something, may have hooked it up wrong, check all your connections, if you cant fix it, take it to a mechanic.
What kind of car first. The car should turn over regardless of what you did with the egr and throttle body. Except possibly the electrical connection to the injector. but even then I think it should turn over. Check the battery cables, check that the battery hasn't run down for some reason, check if you can where you may have put your hand leaning over the car. Dislodged a connection there. No reason to have been around it, but the solenoid wire on the starter. Bumped that and knocked it off.
it, sounds like the crank sensor needs to be replaced or throttle body sensor needs to be cleaned.
No, the throttle position sensor detects how far open the intake is. The crank position sensor watches the rotation of the crankshaft.
This problem turned out to be the "crank sensor" part was $70.00 from the dealer, 2.5 hours to replace. I beleave the crank sensor went bad when I cleaned the engine before selling it.
probably misaligned your crank sensor.. I'm dealing with the same problem, might need to replace with new and make sure to gap properly.
It has both.
Have you replaced the cam and/or crank sensor?
we had the same problem and replaced all those things and it ended up being the throttle body position sensor.. maybe that is your problem
It should be on or near the throttle body.
ur car is building up a lot of carbon or blowby on the butterfly valve (throttle body) u need to press the gas a little in order to start it when it fails to crank BUT U NEED TO ONLY CRANK IT THAT WAY FOR EMERGENCYS UNTIL U CAN GET HOME AND CLEAN IT OUT that is very important
replace the valvcovers you need to pull the motor you can buy a crank kit for this jeep,if it is knocking this means that a bearing is bad on the crank this needs to be replaced,both the crank and all the bearings
replaced crank case valve location at valve cover
Check for proper bearing clearance. It is easy to get the wrong size bearings.
