Help I just purchased a used 1991 Jeep Cherokee Briarwood. The battery was dead, so I purchased a new battery, installed, all power comes on but starter wont turn over? Need help on resetting the factory security system, only has key no remote.

gauge or sensor could be bad and could be oil pump going bad....hope this info helps and if so please leave rating on this post and good luck.

IT CAN BE A LOSE OR BAD BATTERY CABLE END. IF IT START RIGHT BACK UP. HAD THAT PROLEM ONE TIME.

Assuming that the transmission is a automatic, you fill it through the transmission dip stick tube. Just make sure you do not overfill it.

Most common cause of power loss is a stopped up catalytic converter. If you are saying it shuts off while driving, most common problem is the crankshaft sensor. IF you haven't changed the plugs or wires in the last 30K, it is definetly due for plugs wires, and probably cap and rotor button also.

could be a fuel pressure problem.. fuel pump could be going out and loosing pressure..

your windscreen fluid is low

one of the bulbs is shorting out,

 For your 1991 Jeep Cherokee 2WD 4.0L MFI :
  Foot pounds (Final torque) 

  Note:
  Torque sequence ------------------  
  front    | 12  8   4   1   5   9  13 | 
  of | | 
  engine | 11  7   3   2   6   10 14 | 
  ------------------  
Final torque must be reached in 3 equal steps  
  Step 1: torque all bolts (except bolt 11)  
  to 110 Ft/Lbs  
  Step 2: torque bolt 11 to 100 Ft/Lbs  
Recheck final torque in sequence  

are they workin on the out side of the vehicle if so behind the dashboard there is wiring that plugs into it check and see if those are plugged in and the cig liter there is a plug behind it and the radio there should be a fuze in the back of it if not on the radio check to see if you have power to the radio and see if the ground is connected good

if security system is on motor should turn over just not start check wires at starter for 12volts and make sure motor is not locked up
