Problem is worse when fall temperatures drop.
Jeep will not turn over until check-engine light comes on, a clicking noise engages in the elctrical box, and the fuel pump turns on. During the summer, this is only a 1-2 second delay. During the winter, I turn the iginition on, but don't crank it over and it can take up to 10 minutes before the check-engine light comes on, at which point she cranks over. Clearly the fuel pump isn't kicking in, but why only when it's cold? I've already replaced the fuel pump relay. No difference.
Anyone else experience this?
