alright today i replaced the oil sender unit and put a new tranny filter in it and my friend unplugged the MAP sensor and another sensor by it and i unplugged one by the oil sender unit but we plugged them back in and now my jeep cranks and cranks and cranks and will barely start?????

Open up the connectors, again, that your buddy opened earlier and check for bent pins. Also, since you were messing with sensors, remove your negative battery cable for a 10 count and then put it back on and try to start your Jeep. This will "flash" or reboot your ECU.

 

What does "barely start" mean?..Does it start or not?..Are you SURE you plugged everything back in as it should be?..No vacuum lines were dislodged?..Have you checked for any trouble codes in the computer?

 

k ill give it a try also my check engine light came on so i put it on the reader and it threw 3 1-Map sensor2.throttle position or pedal or sumthing 3.map sensor again

 

It starts just takes along time almost to the point where its not going to then finally kicks over...there is small hole in the pcv line but i covered it and still same problem

 

k i just took the neg off for a couple min then put it back on primed the fuel pump 3times and she started right up ill see if its still ok in the morning thanks for yalls help
