Scan the computer for fault codes. Check that fuel filter is not obstructed. (if old, just change it) Most common problem is the crank sensor but do not just start swapping parts: it can cost a ton of $ and not cure anything!!

Well it seems that a leak has shorted out some of the circuits. This may be able to be resolved if nothing has suffered permanent damage, but that will have to be diagnosed by a professional with access to the Jeep. For now, disconnect the battery keep the Jeep in a dry place so the moisture can dissipate.  Use a hair drier or fan to help speed up the drying process.  While this is going on, you will have to search for the source of the leak and get it fixed, the most common area for leaks is around the windshield.  If no permanent damage has been caused, and the moisture is all dried up then you may be ok.

Check the cylinders Commpression. over 115 psi is good, 120 psi is normal.

At least take the time to remove your computer connector & check & clean all contacts with battery disconnected, negative first.. Clean good with an electrical cleaner spray can. re-connect then re-connect battery, with negative last.

????1762 should be a transmission problem!!! Makes no sense at all.
Review: you had a tps code (but the engine ran well?) You changed it and it threw injector codes and ran poorly...You took it out and put the old one back (was code still there? Did it run well?) You put another new one in and now you have a transmission code? and how is it running?
Only commonality here is that the tps runs in tandem with all other sensors Make sure you clear old codes after doing any work and see what comes up after driving through a few cycles/ And get a volt/ohm meter and test the tps to see if in fact it's out of range. It somehow sounds more like a MAP sensor problem..or even a harness problem....but, test before getting anything else.
