    In reality, the engine light is a good thing...Have your codes scanned (most larger parts stores do that free) The scan results should help identify what part of the system is causing problems. Before having the scan done, check every fuse in both fuse panels though,... if one is blown, it is possible to create false readings in reaction to that. You will also need a good wiring diagram (chilton manual is good) and a digital multi-meter in order to do further system testing. Guessing is never a good way to go with gets costly and unless you are very luck, it won't help. All your engine sensors work together...Therefore, I'd need to guess at what's causing the problem. Only thing I suggest is to do the testing, write down what you tested and the results compared to the values published in the manual. If you have a problem with anything along the way, I'll try to give you the best answer possible.

    hey there, yes we had it tested a few times now and they still hadnt fixed it. thats why i have decided to try myself instead of them just guessing. they say it says that there was a injector problem. they replaced all them an same thing. were do i start? were they left off?

  • Richard Scordino Jun 03, 2010

    Get yourself a chilton manual and a multi-meter. Chilton wiring diagrams are far better than haynes.
    Do not begin where someone left off. Start at the beginning and take notes about what you find.
    How and when your injectors fire is determined by the computer after it reads all the sensors, many of which share common wiring. Check all the fuses before doing any testing. Check power at the computer and continuity of all wiring between the computer and each sensor (best done with battery disconnected) Compare what you see with what the manual tells you.

Why would my jeep Cherokee not be getting gas to engine if we rebuilt fuel pump still not doing it

A fuel pump needs power and ground to run. If could be anything from a bad fuse, bad wiring, bad relay, bad computer. IF the pump is getting power and running but there is no injector pulse than again it could be fuses, relays, wiring, computers, or switches.

in the comments below add a year and engine size along with some more specific inf (is the pump running, is there power to the pump, etc)

92 jeep cherokee engine cutting out after 30 minutes drive. Random occurrence/highway driving at 45 to 65 MPH. Engine cough/sputtering is dramatic and eventually corrects itself.

Sounds like you may have dirty injectors. Have you tried a good fuel injection cleaner? Lucas is a good product that works. You may have to use it in 2-3 tanks of fuel if the injectors are real dirty.

It would help if you found a shop with a code reader for a 92 Jeep and had them give you the codes. Unfortunately the free code reading service offered by auto parts stores only works on 1996 and later OBDII vehicles. Pre 96 is OBDI, from around 89-95, and requires a different reader or module for each manufacturer. Many shops use a Snap-On reader with different modules, and should have the Jeep module. Cost will vary, but the codes will help diagnose your problem if the injector cleaner doesn't fix it.

2005 Jeep Cherokee miss fire on fifth cylinder

Pull the spark plug to see if it is oil fouled, preventing firing. If it is, you may have a mechanical problem in cylinder 5- do a compression test to check for low compression in that cylinder.

If plug is clean or only showing black sooty deposits from unburned gas, the problem could be either in the secondary ignition (plug, plug wire, coil), or an injection problem. Try a known good spark plug and spark plug wire, also a known good coil, if plug and wire wasn't it. If checking for spark, you need to see a blue snapping spark when cranking engine to verify good ignition. A weak or orange spark, or intermittent spark is an ignition problem.
To check injection circuit on number 5, you can purchase an inexpensive "noid light" at parts stores. It plugs into the injector connector, and if circuit is good the noid light will be blinking when cranking the engine over. It is rare for injectors to fail, but if circuit is good and no gas is getting into the cylinder, injector may be bad or plugged.
Good luck.

2004 Jeep Grand Cherokee (63,000 mi - V8) Check engine light indicates #1 cylinder misfiring. Spent $$ getting system flushed for carbon residue. Drove 3 weeks, started up, ran rough, and light came on...

The miss,does not just come and go,if it is a engine valve,replace the coil and boot,go from there,if this does not solve the problem,then the injector is gone out,or going out.If it is a engine valve,the miss would never get better,then worse,it would be the same all the time,get him to run a air compression test,get the valves up(close)and see if any air is detected threw the exhaust,or the intake,it will be present if the valve is the problem.

'04 grand cherokee limited, 4.7 ltr, quadratrack 5 speed. At idle, engine runs rough at times and at the exhaust, you can hear it missing. Had it to the Jeep dealer twice. Changed plugs, had PCM reflashed,...

sounds like you have a coil or 2 arching out,they would have to watch misfire mointor on scan tool to see which cylinders are misfiring,also there is a tsb on that, requiring a reflash,but you said that was done,hopefully done right,dealer unable to find problem,what kind of tech is working on your jeep??? well good luck, hope this helps.

My 1996 Jeep Grand Cherokee cuts off while driving

Sounds a whole lot like a dirty or malfuncitionig idle air control valve. A coil would generally show up as a miss under load or high rpm, crank sensors generally work or they dont, only sometimes giving you a miss, but that would be all the time at any rpm. Computer, I doubt for too many reasons to list. Could also be related to a bad throttle position sensor or a very slight vacuum leak.

Engine runs fine when started, put it in reverse and it starts to

probably neither. You should do a compression check, and check your transmission fluid for dicoloration and metal shavings.
