I have a '94 TJ with the 4 cylinder engine. Will not start, I replaced crank position sensor, rotor, cap, wires and fuel pump but still won't start. I could use any help. Thank you.

Would an ignition switch cause this issue? Thank you
It cranks, but no spark. You are right. I parked it in that garage for the winter but went to start it and here I am. I did throw parts at it, but now I'm at a loss.
Start working your way back. Use an ignition spark tester (one with the adjustable gap). They’re like 6 bucks and that can help see if all cylinders are getting any spark and if so how strong of a spark they are. Then you can work backwards to see if it’s a lack of ignition coil strength or possibly the circuit is

Thank you, going to dig into it tomorrow.
Check all fuses. Swap your horn and fuel pump relays and see if the system primes on a cold start key on. I'm still interested in the PCM/PCM connections.
I removed the PCM and checked the pins and everything looked good, pins looked good. Thanks for responding.
Someone told you check PCM'S. I have a '94 Wrangler with a 4 cylinder engine. Thank you
Do you have a 94 or a 97? A 94 is a YJ and is a bit different.
Yes I messed up listing. It's a '94
