ok,i went out today and let it run...it ran,threw its fit and died....i poured some fuel down the throttle body....it still acted the same. so...where am i at on testing now?...could it be the pick up module? map sensor? i dont even now what the map sensor does...but i really need to get this figured out. i would think if the pick up module was the problem that when i poured in the fuel it still would start...same way if it was a fuel pump or filter. or am i wrong. i really need help on this

ok....bought a fuel pressure tester....fuel pressure stays at 31 pounds. i replaced the temp sensor,because i was led to believe that the ohms reading on it was out of spec...guess what...i was told wrong.....the ohms on my old one read 630 when at 210 degrees. i bought a new one....it reads a little over 800 ohms at 210. still throws fit. i unplugged the o2 sensor and it still acts up....im tired of throwing money to it....im tired of it not running. someone please tell me what the hell is going on. i dumped fuel down the throttle body....it still didnt run right....so if the pick up in the distributor is bad(and that is what controls the injectors) then it still should have run....coorrect?

update....i just realized a friend of mine had a haynes manual for the jeep. looked and found how to pull codes....i get:
33..a/c clutch relay
25..idle air control circuit
13..manifold absolute pressure sensor
32...
43....misfire
ok,so i even changed the throttle body and tps and iac. so i guess tomorrow i will try to see if the map sensor on my 89 will work on the 92...if so..i will see if this changes anything. the code 32 i cant find any info on,it definetley runs a code 32...checked multiple times. if its not the map sensor the only thing left is the mat sensor or the computer..right?
