#482 of 592 Re: 1993 Jeep Cherokee Sport stalling after start up [tidester] by sarge836 Mar 03, 2009 (11:53 am)
Replying to: tidester (Feb 28, 2009 11:19 am) Tidester, still not fixed, this is what I have done:   Changed Fuel Pump Changed fuel presure regulator Changed idle control Valve Changed Computer (exact same one from Junk Yard) Chaned Fuel Filter   Is there anything else you can think of on my 1993 Jeep Cherokee. Its starts, idles for a moment and I can give it gas and rpm's go up then just stalls like it's out of gas. Starts right back up then dies out again. There was something about a throttle positon sensor or something???? What is that. Thanks so much for anymore ideas. This is a straight 6cyl 4.0 Jeff Replies to this message: tidester (Mar 03, 2009 2:17 pm) sarge836 (Mar 04, 2009 3:48 pm) tidester (Mar 04, 2009 4:13 pm) and 1 more... mypos (Mar 05, 2009 8:37 am)

Replying to: ike21 (Mar 02, 2009 7:59 pm) It appears to be fixed, but just in case where is the Camshaft Sensor located? I've put over 150 miles so far on it and no stalls. Hopefully it is now fixed. thanks for the info.

Replying to: sarge836 (Mar 03, 2009 11:53 am) The throttle position sensor (TPS) is used as input to the electronic control unit (ECU) which adjusts things like ignition timing and fuel injection. It may be worth a look to see whether that is the problem.   tidester, host SUVs and Smart Shopper Replies to this message: sarge836 (Mar 04, 2009 3:48 pm) tidester (Mar 04, 2009 4:13 pm) sarge836 (Mar 05, 2009 4:16 am)

Replying to: tidester (Mar 03, 2009 2:17 pm) Tidester, Well changed it all to include the TPS none of that but I did fix it.   I couldn't believe it, about 4 years ago had the same issue but thought this was for the engine to fire. It was the ballast resistor (ceramic piece) mounted to the side of the engine compartment that just has two wires going to it. What I did was just take off a bunch of parts at the junk yard. Earlier I was on Auto Zone website just going over the trouble shooting for "stalling" it did mention that like 20 possibilities down the line. I didn't think anything of it but grabbed it at the last min. Well I was all pissed off after nothing worked and tossed a wrench in my tool bag and noticed that "ballast resistor" or ceramic piece and just plugged it in. Jeep ran like a charm after that.??? Thanks for all your help...Jeff Replies to this message: tidester (Mar 04, 2009 4:13 pm) sarge836 (Mar 05, 2009 4:16 am)

Replying to: sarge836 (Mar 04, 2009 3:48 pm) Thanks for letting us know. I'm glad you got it fixed. I would never have thought of that!   tidester, host SUVs and Smart Shopper Replies to this message: sarge836 (Mar 05, 2009 4:16 am)

Replying to: tidester (Mar 04, 2009 4:13 pm) Me either, thought that was just something to do with the ignition and firing. Something to think about if anyone else has this issue. 5.00 part and 1 week of trouble shooting. Actually runs better now too that I changed basically everything else., Have a good day...Jeff
#488 of 592 95 JGC fuel issues by zs711 Mar 05, 2009 (6:17 am)
On start up jeep wont start, engine just turns over.wait for several minutes then hear ticking noise from" fuel pump" and "auto shut off" relays.once ticking stops, jeep will start and run just fine.would the pressure regulator cause the delay of solenoid activating ?started with just 1-2 min. delay now is 15+ min. delay for the pump to kick on.I have changed both relays.

Replying to: zs711 (Mar 05, 2009 6:17 am) Could be an issue with your fuel pump, but check and see if you have a "white ceramic ballaster" mounted on the right side of the engine compartment, could be on the left, there will be two wires going to it, located on the ends of the ceramic piece. This controls voltage with the fuel system on my jeep and that is what the issue was. If you have one, just jump the two wires together to test it and if everything is fine then you will need to replace it right away. Also like you said could be the fuel pressure regulator but check the easy stuff first. Well they are both easy to change.

Replying to: sarge836 (Mar 03, 2009 11:53 am) make sure that you have your fuel pressure regulator installed correctly with both the large and small o rings and adjusted to the right torque.. i had the same problem and the regulator i got from auto zone was missing the smaller o ring causing the fuel pressure to drop and all the fuel drop back into the tank.
