Need help!!! Jeep won’t start
Good day every one. I’m new to the Jeep community and am in need of some help. I have a 1991 XJ that I picked up fairly cheap. When I bought it the young man stated that it would start but immediately shut off which made me think something wrong with the ignition but when the jeep arrived at my house I learned that it had a broken steering column. I began by replacing the steering column and key and then could get the vehicle to crank but it would backfire. And then proceeded to check the timing and put the Jeep in timing (4.0). The vehicle would just crank and not start. Make sure all the grounds we’re taking off and cleaned and still no start. I then verified that I had spark and as it appeared week I replaced the ignition coil, the crank position sensor, spark plugs spark plug wires, rotor, distributor, cap just to be safe. When replacing the CPS I did learn that he had recently been replaced along with the throttle position sensor. Still the jeep will not start only cranks. With the ignition is turned on you can hear the fuel pump and with ignition on we’re getting 45 psi at the rail and went cranking 55 psi. We’ve tried starter fluid, we also checked the neutral safety switch and still nothing. I took the computer in to be tested I was advised that the computer is good as well as previous repairs done to it have held up well. I was told to test pin six at the computer for 5 V and pin seven for 8 V and they both checked out, was also asked to check pin 24 And I get anywhere between 7 to 8 V while cranking. I was told the pen 19 should have the same amount of voltage as the battery one not cranking however I’m getting .24 V there. I will be tracing this wire to see if there’s damage however wanted to see if there’s anything else anyone can think of that may help us get this jeep to start. Any help would be greatly appreciated, thank you all in advance!

PO0117 and PO0118
Concerning these two codes, "P0117 (M) ECT Sensor Voltage Too Low Engine coolant temperature sensor input below the minimum acceptable voltage and P0118 (M) ECT Sensor Voltage Too High Engine coolant temperature sensor input above the maximum acceptable voltage."
I replaced a coolant temp sensor because of a busted plug...it would rotate 360 degrees. However, the replacement sensor provided lower than normal coolant temperature, so I again replaced the sensor. This time, the engine check light came on with codes PO0117 and PO0118.
Moving the wires by connector would turn PO118 on or off, but PO117 would stay on consistently. I reinstalled old sensor and the check engine oil light stayed off, but coolant temp indicated lower than normal. So, I replaced the sensor, this time with a brand name one, and the check engine light did not come on, but moving the wires would slightly move temp gauge. This time, I replaced the electrical plug and all is well, coolant temp is normal and electric cooling fan turns on when it's supposed to.
