Check if there is any blown 15 or 20 amp fuses. Located in the engine compartment. There should be a Breaker box with fuses and relay switchs in it. Look forIgnition or Ing. I know some cars don't have names for fuses on the breaker box cover like ford. If so look up in the internet. As in cirucit breaker digram - If fuses and relays are good then fine. Then If remeber correctly check the fuse box under the dash board or in the glove box. Some Chrysler Products like my Dodge van has two fuse boxes. One under the dash or in the glove box, as well in the engine compartment. Also look for PCM or ECM fuse too, ECM means, Engine Control Modular It also controls engine spark and fuel injection as well as other things in your jeep. Its fuses for that is 7.5 amps with 5.6 volts. If these of good. Then replace the coil and crank sencor or have it tested at Autozone. A bad crank sencor most defintly would make your car to not have spark. It works with the movement of the engine with little windows on your crank shaft with the front crank shaft pully or in the back of the engine inside the bellhousing of the transmission. Most likely on the side of it. Its tell the onboard computer were to fire spark with fuel injection. Without it the computer dont where to spark the #1 or #2 or #3 pistions for that one, its 6 cyilders. Hope this helped, wish you well.
there is only two things left. the crank sensor that is located at the top of the transmission bellhousing or the pick up inside of the dist. it is that black plate that sits between the cap and the dist housing. hope that helps.
wall5552: there were two engines used in 1992 Jeep Wranglers.
A 2.5 liter and a 4.0 liter. HOWEVER>>>> The location for the crank angle sensor is the same for both.
It is located on the bell housing up near the front at about the 10:00 PM position.
The Cam position sensor is located in the Distributor on both engines as well.
Should be on the bellhousing on the drivers side just where you need rubber arms to reach it.Should have no continuity between b&c terminals (check with ohmeter) Harness plug is usually on the drivers side between the master cyl and the back of the engine (unless someone moved it)
Take the distributor cap have someone crank the car and look if rotor turns, look at rotor conditions, I am sure that you have replaced it, hot wire from positive on the battery to positive on the coil, if car starts after you have a problem on the key, Is it fuel getting to the injectors? after You replaced so many things,if your rotor is not turning when You crank the engine, your timing chain must be defective or timing gear,
This seems like a fuel pump or fuel filter prob. The pump more likely. Will it fire up with gas poured into the carb? If so the pump. If not, we will need to look for another prob. Don't buy parts you don't need! Frankster016
