1998 Jeep Wrangler - Answered Questions & Fixed issues

disconnect head lights, and replace fuse. Then turn the light back on to see if it blow a fuse again. if not, plug on light in at a time. You might have a bad headlight???? then unplug that one if nothing happens. Then plug the other one in. It could also be a bad taillight bulb. I have had bad tail light bulbs. Do all of them, one at a time.

I would look for a draw that is killing the battery.

check fuel pressure regulator and fuel pressure. should be between 45-50 psi and hold steady.. shut off car and let sit 5 min if pressure drops more than 10 lbs one of the two is bad...

You can mount a fuel pressure guage to the engine fuel rail at its bicycle valve bleeder, with tof see if it has pressure when you first turn on the key to start. You may be able to hear the fuel pump running by listening at the fuel tank fill cap that you would remove for that moment. By turning on ignition to start, not run, you are energizing the fuel pump to bring up pressure that should happen in several seconds. So, check if it gets to normal fuel starting pressure, maybe 45 to 60 psi. Then turn key all the way to run, to get car engine running and watch the fuel pressure to see if it stays pretty constant at that 45 to 60 psi. Turn engine off, and watch how long it takes for fuel pressure to drop, and it should not happen fast but instead over 15 minutes or more. That might indicate your fuel regulator valve isn;t working right. Is it possible your starting system is the culprit, say some battery cable loose that may make starting hard or eventually quit until you tighten these cable ends at battery and starter.

122 is not a valid code, codes look like this, letter "P" followed by four numbers, a typical code is P0028, which is a VVT control issue.

You are going to have to check the codes.Then we will know what the engine is asking for. A code reader can be bought at Canadian Tire for $30 to $40.

You changed the master cylinder and vacuum booster and have no leaks anywhere, but did you bleed the entire brake system after you did this work? A little bit of air in any of the lines will make the brakes ineffective.

Standard transmission? If so the clutch may be broken/damaged or far out of adjustment. Can you select the gears with the engine off? If so then take a real good look at the clutch.

the 4.0L inline 6, next time tell engine, get the pump from jeep, china, or fleabay , who's pump is it? matters, in many cases.Duracrap pumps.? wrong methods. cause it ,did you read the SM? all pulleys must be in perfect alignment. (the law of belts 101) unless a GM Corvair... LOL below is the SM, free, and real see TJ, see chapter STEERING what does it tell you,.... my guess page 7 skipped see the word flush? the real book, called SM, serv. man. http://www.morris4x4center.com/knowledge-base/index.htm?utm_source=cj#service

The engine freeze out plugs are all one size. The block heater takes the place of a freeze out plug.

radio dead, that means no sound or nosound nor dial data? does the am/fm and cd all fail, using real CDDA disks(store bought) ? if the radio is totally 100% dead that is lost power to radio. fuses or lost ground to the radio. the check engine light means one thing,. get the car scanned, 1996 to now, all cars USA. you scan it, they scan it. i take it car starts and drives perfectly? head lights work> and all outer things?

engine pan or trans pan,(guess at engine) what's up doc.? what is the job. lost the gasket? lost the bolts.? not sure what going on here. buy a new gasket from Felpro and bingo? there be a pattern

Do a voltage drop test on starter circuit , Bad positive cable or negative cable . Starter Voltage Drop

If both heater hoses are getting hot, it could be a blend door problem.

The radio has 2 power feeds, one is wired to battery so it has power all the time for memory and the other power feed is from the ignition circuit so when you turn the ignition on it turns the radio on. You need to determine if the ignition feed is shutting off with the ignition. If the power feed is shutting the power off then there is a problem with the radio. If not then there is a problem in the ignition circuit.

sounds like a ignition problem, try new cap rotor and wires and plugs if this does not fix your problem it is either your coil or distribitor

Well that's ABSOLUTELY NOT TRUE, the voltage regulator is in the ALTERNATOR. This vehicle needs an alternator and that should take care of this problem. Good luck and thanks for using FIX YA

Depends on which engine, and normally one would use the dipstick to tell when it is full.
