In the image from post #39 it shows which spot is which number.
I'll have to put the battery on the charge to attempt to crank it. It may be all day without result. I've let the battery sir for years un-tended.

OK I did tons of diagnosing. Bottom line I think the ignition switch is bad? But dont know. I used the wiring diagram and unplugged the ignition switch and computer and actually did a continuity test on all wires.They are all good. I am having problems tracing the fuel pump wire. If you want to e mail me ill send you the hole book for 88 xj private mesage me your e mail.

On the chicken scratch paper upper number are to the ignition switch un plugged.
bottom numbers are from the relay to battery terminals. Positive unplugged so it wont ruin the continuity checks.
Pin 87 got me thinking I found something wrong. I realized this wire goes to the pcm so I unplugged the pcm and did continuity checks and all tested good so i test all the wires according to the wiring diagram. NO BROKEN WIRES.

Please help me trace the fuel pump wires so i can do continuity test from the relat or pcm On image 4 find the relay follow the yellow wire up to the right says side wire 4 diag con 02 .....Were does that go to??

OK there's the problem. 87 is supposed to go to the fuel pump. 30 goes to the PCM. You have the fuel pump hot wired (to a point).
