89 jeep Wagoneer shut down new fuel pump will restart with starter fluid

SOURCE: jeep wount start

When you turn the key on all the lights come on normally? and when you try to start you lose the lights and hear a click? If so the battery cables are loose, or broken. If thats not the case it could be a relay or stuck starter or switch. You can try a screwdriver at the starter hit the little wire and the big wire it will spark and should turn the engine over "MAKE SURE IT IS IN PARK WITH THE BRAKE SET" do this last, if you do all that and it turns over you can say the starter and cables are good. Next replace relay and try, still nothing get a new switch. Hope this helps.

These 3 work in Conjunction with Each other. I would replace #1 First and see what you have got. Let me Know!

If your steering box is in the same place mine is, the adjustment is hidden under the radiator shroud.Generally this will remove a bit of steering play but it has to be done carefully to avoid binding.
What you really need to do is to check the entire front end for any play. Remember that "acceptable" play in one component when added to "acceptable" play in several other components = unacceptable overall play.All bushings, joints etc must be checked. Shocks need to be in good condition as well. If everything is in good condition, find a good alignment shop and ask them if it's possible to add a few degrees of positive caster to your present settings. If you have adjustment for this it will help to keep it going straight at speed. (may make turns a bit harder but with p/s it should not be noticed.
good luck

turning over is cranking (different words for same thing) You need to do some testing to determine what is failing. Good guess would be the crank sensor however without testing, you may not solve the problem by just replacing it. I suggest you obtain a decent manual such as chilton or haynes and using a digital multi-meter, perform the tests on your sensors outlined. Since the problem is intermittent you need to test both when working and also when in "no start". Testing helps avoid changing non-failed and expensive components, and is always the best thing to do before buying parts.
No one here can tell you what's wrong simply because no one can do that essential part of diagnostics by "long distance"
Good luck!! (if you need help with anything you discover, feel free to ask!!)
