  1. Well, #5and6 injectors not getting any signal from PCM. Fuel pressure perfect. All sensors working fine. Still coughing and sputtering. Replacement PCM came in the mail today. Installed it and now the engine purrs like a kitten. Hated to have to take all the time to test everything, but now I know that everything is all good. Haven't heard much good about the computer rebuild industry but hopefully the third time is a charm. Thank you all the advice and now that I own a Jeep I'm sure I will talk to you again. Mike
  2. Moses, I was looking up some of your other posts trying to find out information on your test light setup. I ran across a guy that said when he plugged his intake it still ran. I tried it and it died immediately. No vacuum leaks. I unplugged numbers 5 and 6 injectors and the idle smoothed out (not rich) and started running better. I unplugged each of the other injectors one at a time (5 and 6 still unplugged) and a noticeable change in the idle. Also, with 5 and 6 unplugged, the vacuum is up to 12 to 15 inches! I definitely have some more diagnostic work to do.
  3. Yes I have a factory service manual. The distributor is in exactly according to their specs. The haven't checked the timing as per the instructions yet. I went ahead and purchased a new coolant temperature sensor. Did not make any difference though.
  4. Oh. Almost forgot to mention that when I hook up my timing light, no advanced options, I cannot see the timing mark.
  5. Moses, I have the entire manifold plugged except for the MAP sensor had that plug that one time also no difference in the manifold vacuum. I got carried away on another project of fixing my exhaust leak and at the same time replaced my o2 sensor. The TPS ohms test ok. The coolant temp sensor at room temperature which is approximately 80 degrees reads open. No resistance at all. May be a problem? I did get into the timing chain and it is position exactly lined up the marks on top dead center number 1 compression. Pulled the distributor out and double check the indexing on it. The only weird th
  6. I did the timing chain slack test and had 8 degrees deflection. Meaning with the timing mark at 0 I backed it up to 8 degrees before top dead centre when the rotor started to move.
  7. The odo says 205k. 90k of which were supposed to be tow miles. (not sure I believe that). Engine is dirty enough for me to think that no work has been done for awhile. I will look at the link. Thanks
  8. Moses, First of all, thanks for the quick response. It's great to have a place to go to get nolageable information. I was so frustrated by the time I did the last post I didn't put down all the things that I have checked. I did do the fuel pressure test. At first I did have a high pressure approximately 70 psi. I thought great I found the problem. I traced it down to a pinched hose return line on top of the fuel tank. The tank was removed the lines straightened out and now the fuel pressure is 32 psi. I have the EVAP canister disconnected at the moment the lines plugged so as not to hav
  9. I have a 95 YJ 4 litre let's running extra rich. It will foul out the spark plugs with carbon fouling within a few minutes. Let me start at the beginning, I bought this Jeep running terrible. I was told it had a dead battery while jump starting they hooked up the cables backwards. I thought this was probably true due to the fact that both alternator fuses were blown. I drove it nine miles home and went through over 4 gallons of gas. Most of that ran out the tailpipe or was dumped into the crankcase. The number 5 and 6 injectors we're running fuel anytime the key was in the run position.
