94 Wrangler no cold start until check engine light comes on

My daughter recently bought a 1994 Jeep Wrangler last fall. When it got cold out her Jeep would not start until the check engine light comes on when the key is in the start position, (the position just before you crank the engine which is a normal condition). When the check engine light does not come on in that position, it will crank the engine over just fine but will not fire up. I have tried a new coil without any luck. I think it might be the PCM but hate to spend that kind of money if it's not that. The computer also does not throw any codes out that would help t-shoot this problem.

it might be a PCM. try a junk yard.
also try unplug the battery and leave it for sometime see if that would reset the computer.
