On my 1993 wrangler with a 2 5 if i try to start it it only fires on cylinder 1 and 3 if i shut it off and try again it fires only on 2 and 4 what would cause this

1993 YJ, 2.5L 4 cylinder jeep wrangler.
new rotor? (do a full tuneup first)/ cap rotor,sparks and wires?
if not why not? carbon tracking is impossible to diagnose
some paths are hidden, on old caps and rotors. why skip this.?
someone fiddled the distributor and touched the distrib, clamp
now injector sync timing is way off.
scan it yet?
check fuses.
this is part of the first Chrysler EFI system.
this engine has a single coil (spark) so if one works all do.
and has CKP sensor that are very difficult.
and cmp sensor in the distrib,(gee scan it?)
i use a INNOVA 3140 scan tool it works in 93-95 (this ecu)
now the CKP, did you mess with it? best it to not touch it.
on the 4 liter. ckp is tuned.(using a paper spacer)

it has a critical gap, but only on the 4.0L it seems
the 2.5L CKP is precision mounted for gap setting fixed.
if you crank the engines, with scan tool attached
it will show DTC errors for CMP or CKP.
or for spark.
The spark is 100% timed off those 2 sensors.
The ECU warns you if even 1 in 10 is wrong.

Sounds like a spark plug or distributor problem.... Change out all your spark plugs and check your wires for breaks. Check fuel injectors for build-up.
