I need help!!! Timing off after new distributor

i have a 99 jeep wrangler sahara
the ear on the distributor broke off wile i was driving which put me on the side of the highway i got the jeep towed to a local shop
i used zip ties to hold the distributor in place i drove it home like 8 miles all was well so it seemed it drove like it normally does
i went to advanced and got a new distributor it was supposed to have the plastic piece and plug it did NOT have it so i took the old one off the orig and put in jeep IT WOULD NOT START so i turned it 180 and it got worse
i returned it to advanced thinking it was the plug etc i got a new one with all the parts
i put it in the jeep and now i STILL have the same proble i HAVE spark but it keeps popping out the air clearner like it is out of time
i have tried everything i know does anyone have some input or had this happen to them before ???
cause the time isnt adjusted by the distrib right ?? it is either in or 180 out correct ????
please help ty

Did you ensure the engine was at TDC before removing the old distributor? Timing is set by the Crank Position (CKP) Sensor, fuel sync by the Cam Position (CMP) Sensor or ignition pickup as many parts stores call it.

Whether you did or not, crank the engine round to TDC with a wrench then remove the distributor cap. If you look at the rotor arm from the side of the Jeep and compare it to a clock face what hour is the rotor arm pointing too? If the engine is at TDC on the firing stroke for the #1 cylinder it should be at roughly five o'clock.

This is called initial timing. I had to show my younger brother how to do this on his YJ last week. You need to find Top Dead Center (TDC) on the firing stoke, right after it blows your finger out of plug #1 hole. Once you have that put the distributor in, with the cap off,and make the rotor button point to where spark plug #1 wire will be. You will have to make sure the oil pump shaft is in the right position. Bolt the ear down and give it a shot. If you have a buddy around have him hold the distributor in place and turn it until it starts up. Find the position where it starts up, then pull the distributor out and ever so slightly turn the oil pump shaft until you have the distributor in the right place. Once you get it you will always remember how to do it haha. If you need me to clarify anything send me a PM.

Good Luck
