My '95 2.5 AX5 YJ has a strange problem, usually in the morning when it is cool. When the key is turned to run, the check engine light does not turn on right away. There is a delay of a few seconds and then the relays in the power distribution box under the hood start to click rapidly. Once this happens, the fuel pump runs for a short while and the jeep can be started. It seems like the computer is not aware right away that the ignition has been turned to run. If I immediately turn the key to run again (after first returning it to lock) the check engine and fuel pump turn on normally. After letting the jeep sit turned off for about 5-10 minutes, the problem will return. Later in the day when it is hot, this almost never happens but it does once in a long while, usually after sitting turned off for at least a few hours. What could be causing this? What could cause it to work fine on the second try?
Thanks
