97 jeep wrangler 2.5l not running right by taz1973

My Jeep is throwing 3 codes on personal hand held computer reader,:p0108,p1297,p0121. The problems started when I changed my water pump, I had to take it to my mechanic and have him realign my manifold gasket, he told me to change my distributor, so I did. I have 180,000+miles on my motor, I've changed my MAP sensor,TPS sensor, throttle body gasket and the elbow for my vacuum advance. It will run for about 100miles and then throw the check engine light, before it throws check engine it will start to sputter like a mis fire and then at 3,000rpm it cuts out on the throttle and it won't idle. The dealership wants me to have them diagnose it and they also think that my ECM might be bad. I have had it with my baby but I won't get rid of it, please help!

Before going any further, can you confirem it's a '97?
The '97 shouldn't be giving 'P' codes, they should be simple two figure codes like 31 or 64.
The '97 differs from later models in that it uses a version of OBDI which is unique to its model year; later vehicles use OBDII which does generate 'P' codes.

The strange thing about my 97 is the tps i put on is for a 95 the one the dealership give me didn't fit so i took the stock one that came off of my jeep and that is how i discovered that it was a tps for a 95

It's supposedly a '97 that produces '98 and up OBD codes, although the engine may be from a '95, and it started producing these codes after you changed the water pump which apparently required the realignment of one of the manifold gaskets and a new distributor?
 
I guess I'm a bit lost on this one.

Hi Mac24, since about days my jeep starting after 3 minutes and +50 tries turn on the key .. I think it's the starter.. The battery is new.. I hear the fuse contact ! It's possible that problem come from solenoid ? Wire ? Starter ?
 
Thank You Dave

If I understand correctly, it takes many turns of the key before the starter turns, although you can hear it click each time?
 
The solenoid is integral to the starter and can't be replaced seperately, so if the problem lies with the solenoid or the starter a replacement starter is required.
 
It's also possible that you have a bad (high resistance) connection at either of the battery connections, the starter connection, or the engine ground.
That would be where I'd start my checks, and if that's the problem it'll be a lot cheaper than an exchange starter.
