Like I said.... Check your fuel pressure at the fuel rail Schrader valve first, then let us discuss the sensor in the dizzy. First things first. I am trying to avoid you throwing money at this and then hoping it fixes the problem. If your fuel pressure tests are good, then the distributer sensor is likely, but why replace that before you even logically troubleshoot your problem? I am not sold on the no spark issue as your rig runs, despite it being rich. That coupled with the OBDI code stored. Perhaps your spark is weak... but I don't believe we are there yet.

OK perhaps you did skip timing. Just read through your description again and this could very well be the case. Did the original issue happen upon down shifting? I would expect different codes stored though besides running rich. Perhaps I will learn something here?

Yeah bud it won't run at all. This happened last night shifting through the gears I think from 3rd to 4th going about 35-40mph. Just skipped about 3 hard times cut off and won't start back. It seems to be spinning differently than before. Perhaps a little more free and then all of a sudden a catch kinda. For lack of a better explanation. I appreciate you trying to help and keep me from throwing money at it for no reason. So ill listen to any advice. But how I described is how it sits right now. I had to pull it home last night.

Well then, have you verified your timing alignment? A quick gross check would be to rotate your crankshaft to where it is at zero degrees top dead center on the ignition stroke of the number one cylinder. Once there, verify that the rotor is pointing to the #1 cylinder post on the distributer cap. If not, then it may be necessary to pull the timing cover and check the alignment by verifying that the pulley marks align up when they should..

I haven't verified timing alignment. Only have about 30 mins before dark when I get off. And I go in at 5am. So not much time. But tonight my plans are to check alignment at tdc. pull the distributer cap and just have look to see what it all looks like. Like I said I can check tdc. But have never been inside a distributer before so its time to get my feet wet. What I know is I have a spark on only 1 cyl. And I feel like its trying to start on just that one cyl. That's the stuttering I am feeling when I turn the key and it wants to start every now and then. We will know more tonight I hope.

Yes, you would or could. the pickup can replaced as a part of the entire distributor. The price difference is minimal. Replace the entire distributor, including cap and rotor. Mark the distributor and rotor postion before you replace it and make sure it goes back in the same way. Just curious, how many miles on the engine?

128,000 on the engine. I've only owned it for about 3 months and have only put about 200 miles on it. Had to put a transmission, clutch kit, rear main seal while we had the trans out. And painted it. So just really started driving it last Monday. And then this Sunday. Oh well hope it's nothing major. Doesn't sound like it. Thanks ill see what I've got tonight when I get off.

Trans......try disconnecting the vss plug on the tcase. It's a long shot but it does have the capability to cause you a no start if the sensor shorts.
