Your question has to many variables. Cold weather out here in Cen Cal this time of year is mid 40s. Is the problem when the vehicle is cold as in ovrernight but starts ok when it is warm? Does it crank OK but seem like it's not getting fuel? If you hold the throttle slightly open, does it start OK? Back in the game! '94 YJ 2.5 all stock.

Temps here have been in the single digits.if the temps are above freezing it starts much better. It starts fine when warm.Thanks for the warm welcome and the reply.

Instead try cracking the pedal 1/4" or LESS and see if it starts quicker.. A SMALL amount might help but pumping does nothing good for starting. Also try turning the key to the run position to build up fuel pressure before hitting the start position.
