Help, With Paul gone, this has become more of a problem than ever. My YJ is tempermental like most jeeps but now it has decided not to start sometimes. It turns over but doesn't start. Sometimes it turns and turns and turns, then starts and has the Check Engine light on. Then sometimes it just plain starts. I have found though that if I wait for 5-10 minutes it will start right up though. Paul taught me a while back how to pull the computer codes and the ones that I came up with were 12 and 54 and then 55 telling me that it was done with the codes. Can anyone point me in the right direction to fix this thing? I have a name for my jeep, it is Richard when it is good, Dick when it starts to act up, and just plain Broke Dick when it is broken. Any help will be appreciated.  |

Code 12, no big deal means battery disconnected within last 50 or so ignition cycles. Code 55 is end of data code list. NOW, code 54 indicates loss of camshaft signal during crank, and this will cause your no start! You really need to see if you have a spark during the thingy phase, but I suspect a bad pickup coil in the distributor or possibly a module fault. I've also had to repair wiring at or in the distributor on older vehicles.

Do you think that if I just replaced the sparkplugs, wires, rotor, and distributor cap that I would have all my bases covered or am I totally lost? I can handle replacing that stuff, it is the harder stuff I don't know about.

Well, i dont know what year yours is but, my thingy is an 89 with a 4 banger. I have had a similar problem with mine. except when it went it just died. I would try to chage all of the stuff mentioned before. If that doesn't work then i would check your crank position sensor. Mine is mounted on the drives side at the back of the engine. You will have to crawl under the jeep to see it. It will connect right where the tranmission and the engine bolt together. When mine died it died hard. It acted like yours is acting except for the intemittent part. It sounded like it wanted to fire but, wouldn't. The chilons manual calls it something else but, i cant remeber right now what it is. They are hard to find and can be expensive depending on where you get it. I found that carquest has it the cheapest. Hope this helps ya out.

Well seeing as how I am six months pregnant and with my husband in Iraq, I don't think that I will be getting under the jeep or getting into anything to serious. I can change the sparkplugs and all the stuff that goes with that, and I HOPE AND PRAY that that works. If not does anyone know of a cheap but reliable place to take it to around Williamsburg. I will definatly try to replace all that stuff though.

Well, If that other stuff doesn't work then get that part and get ahold of one of the guys on the web site we are up that way everyonce and a while and we have members up that way that i am sure would help out a woman in need. I agree you dont need to be crawling under there. It only takes about 10 minutes at the most to change out that sensor if that turns out to be the problem. Keep us informed and hope all is well with the hubby over there. I just got back on the george washington in Dec so been there done that I am sure he is having it a harder time of it considering the way things are over there now.

Hey Jen, It sounds like either the crank sensor or cam sensor. The crank sensor tells the computer where the engine is by reading these little slats on the flywheel/flexplate as it goes around. That way the computer knows what the position of the engine itself is. Usually this crank sensor is mounted in a hole in the bellhousing right at the engine block. The cam sensor is usually inside the distributor and kinda under the rotor. It tells the engine more directly where the distributor is and therefore TDC of pistons and positions of the valves by knowing where the dist is. This sensor helps the computer decide when to fire the plugs. In my limited experience, if the crank sensor goes out, the engine will have a no start. Period. That is becuase the computer is basically blind as to the engine. But if it is the cam sensor, it will occasionally run, but not well, cuz the computer isn't sure just when to fire since it can't read the distributor. It isn't blind in this case, but essentially needs glasses to place the shot on the mark. If you need any help, I am like 25 minutes away in Hampton and I know where you are located. Just give me a call and maybe I can swing by Tuesday evening after work. Or possibly I can come up on Thursday since I am off that day. Number is 825-4947 FYI I am Joshua, the pain in the butt that had the work done on the Dodge axles.  |

Yay!!!!! ;D The jeep is fixed. It is back to being Richard. Yes. It turns out that it was only a 25 dollar part the entire time. It was the sensor that is inside the distributor. It looks like a flat black circle with some wires attached to it and a contact on it. Turns out that I was only running on a few cylinders, which would explain my bad gas mileage, and it has slowly been going bad for months now. Replaced it today, and it started like a charm and runs smoothly. Just in time for top down weather. Thanks guys for everyone that helped. Jenn  |
