Check engine light

hey guys got a lil probelm. when i start my jeep in the morning or at night it sometimes is hard to start. it will start but its like the battery does not have enough juice. and then the check engine light comes on and stays on. but if i run it for a minute with the light on and shut it off then start it up again the light goes off. any ideas at all while the light comes on. oh and it does not come on all the time just when its really cold or has been sitting for a day or two thanks guys

Check engine light

Redwrangler, I have the same problem with cold starts, I have fuel pressure, and spark, If it warms up to say 20 degrees or so it will start up. I thinking it might be pluged or dirty injectors and the gas is not spraying but squirting and will "flood" that cylinder, because when trying to start it will act like it is flooded. When it warms up a little, -19 now burrr, I'm going to check out the plugs. I have put some injection cleaner it but I have to get running for it to work. The check light does come just like yours does and goes out again after a restart. After it starts it will run rough for 5 mins or so before it smooths out, will start fine the rest of the day. My jeep is a 94 with a 2.5

same thing with my 93 .............whats the voltage say ...............when it would happen to me it would some times read as high as 15 volts i checked the water level in the battery...... it was low so i fill it up but it didnt seem to change anything i bought a new battery ..........and it never did it again the way in yjs if you turn the key on off on off on without starting it it will flash the troble code at you more reason the yj is easier to deal with then a tj magic box needed ......
i didnt think it was that deep
