95 jeep wrangler Yj with 2.5 4cyl. won't start, not getting fire. We have checked all the fuses, changed the plugs, wires, distributor cap, rotor, coil, installed new distributor, and crankshaft position sensor, also replaced ignition switch that was bad. Still not getting any spark. What do you recommend next?

So many of them things could have been checked to see if they was bad or needed to have been replaced. I see this a lot when someone goes to guessing on things and they can end up having a LOT of money invested and still not running.
My first guess since you've replaced all of them things is either you may have a ground issue or a bad PCM.
I would start by checking that you are getting power to everything that you are supposed to be getting power.

Then, I would check that you are getting grounds to everything too! You must have both in order for it all to work! If you are getting both and if you know how to check for both at all places, then I would eliminate the PCM.

If it turns out to be the PCM, try checking eBay.
Hope this helps.

SOURCE: distributor cap and rotor location on chevy silverado

Most chevy 5.3 do not use a cap and rotor. Most have single coil per spark plug and wire. Trace spark plug wires to coil usually above the valve cover.

SOURCE: intermitent starting

sometimes the ais(automatic idle speed) valve gets loaded with
carbon. its an easy fix. you have to remove the throttle body
invert it and you will see the ais chamber and look in and see if it is
built up with soot. carb cleaner should work.if you can remove
the valve for better cleaning. peterjai

Fig. 4: Rotor position with the distributor properly installed-1987-90 2.5L engine




  1. Disconnect the negative battery cable.
  2. Remove the primary lead from the terminal post at the side of the distributor.

The wire connector will contain a special conductive grease. Do not remove it. The same grease will also be found on the metal parts of the rotor.
  1. Disconnect the vacuum line if there is one.
  2. Remove the two distributor cap retaining hooks or screws and remove the distributor cap.
  3. Note the position of the rotor in relation to the base. Scribe a mark on the base of the distributor and on the engine block to facilitate reinstallation. Align the marks with the direction the metal tip of the rotor is pointing.
  4. Remove the bolt that holds the distributor to the engine.
  5. Lift the distributor assembly from the engine.

To install, if engine was not disturbed:
  1. Insert the distributor shaft and assembly into the engine. Line up the mark on the distributor and the one on the engine with the metal tip of the rotor. Make sure that the vacuum advance diaphragm is pointed in the same direction as it was pointed originally. This will be done automatically if the marks on the engine and the distributor are line up with the rotor.
  2. Install the distributor hold-down bolt and clamp. Leave the screw loose enough so that you can move the distributor with heavy hand pressure.
  3. Connect the primary wire to the distributor side of the coil. Install the distributor cap on the distributor housing. Secure the distributor cap with the spring clips or the screw type retainers, whichever is used.
  4. Install the spark plug wires. Make sure that the wires are pressed all of the way into the top of the distributor cap and firmly onto the spark plugs.

If the engine was turned while the distributor was removed, or if the marks were not drawn, it will be necessary to initially time the engine. Follow the procedure below.
To install, if engine was disturbed:
  1. Rotate the engine until the No.1 piston is at TDC compression.
  2. Using a flat bladed screwdriver, in the distributor hole, rotate the oil pump gear so that the slot in the oil pump shaft is slightly past the 3:00 o'clock position, relative to the length of the engine block.
  3. With the distributor cap removed, install the distributor with the rotor at the 5:00 o'clock position, relative to the oil pump gear shaft slot. When the distributor is completely in place, the rotor should be at the 6:00 o'clock position. If not, remove the distributor and perform the entire procedure again.
  4. Tighten the lockbolt.

SOURCE: caster adjustment for 1990 jeep yj wrangler

caster is adjusted at the rear of the lower control arms. Camber is fixed and cannot be adjusted by normal means (though special off-set ball joints are available to do that) Toe in is adjusted by turning the sleeves in or out on the tie rod ends. None of this should be done at home though crude adjustments can be made in order to get the front end reasonably straight. Adjustments are made on an alignment machine that allows precise adjustments to all you mentioned as well as front/rear tracking.

95 wrangler yj. has no power at high speeds

Have you had fuel pressure tested, and/or filter changed. Have you checked for plugged exhaust, such as catalytic converter? Quite often engine will also run a little hotter than normal when exhaust is plugged.
