22 means coolant sensor voltage too high or to low.23 means intake air temperature sensor input is below the minimum acceptable voltage or above the maximum acceptable voltage.24 is throttle position sensor i had a 95 it wouldnt start looked tps wire was loose fixed it it ran look for that or replace your tps then get back to me

You need to use a meter and check for the 5 volts across the connectors of all 3 sensors. I thought you replaced the distributor and it was running.

I do agree go ahead and check all three while your under there

the 95 i had it would kill the battery and i would have to jump it with my 98 grand cherokee before it would start and if it did start it would run ruff and soon as you breath on the gas it would die again its a good possibility it could be all three you can take the voltmeter and check. i checked my tps on my 98 by taking it off and examing the peice of plastic the throttle shaft sits in and turns it was wollard so the throttle shaft had to turn twice as far before it would start to compress the spring inside the sensor,either way wish you luck with it

Disconnect the battery for 10 sec. and retry starting it. Recheck the codes.

O.K., after the reset, the same issues remain. Like previously suggested, you need to check power for these sensors to track down the issue. These sensors are all common with respect to power and are downstream from the O2 sensor. So if all these lack voltage, then check the O2 sensor wiring and make sure it is still intact with no visual damage.

If no power at the Map sensor, then follow it back to the CTS (coolant temp sensor) located on the thermostat housing. Power there?

Confused.... Are you talking about the CTS? If power is at this connector and not at the Map, then you have either and open or short to ground between the two. Repair this wiring at this point and then perhaps your issue will be resolved.

Read further into your comments. This could definitely be your issue. Fix and then report back!
