my jeep will not start unless its above about 10 degrees celcius. this is very strange and i cannot figure it out. 87 4.0. i can hear the fuel pump every time, but can't seem to get fuel. as soon as it warms up outside a bit it will start. i tried to find some seafoam, but i live in canada and can not find it anywhere. anyone have any ideas what my problem could be?
it sounds like moisture is getting into your wiring because it being that cold. try some di-electrical grease and spray it on all your wires. Take them apart and spray the connectors too.
check for fuel pressure at the fuel rail, but I think it is the moisture thing that is giving you trouble because it goes away when it gets warm outside drying your wires.
It might also help to take a can of carb cleaner to ur throttle body. Just spray it on a clean rag and wipe the whole inside out. Even if this does not fix the problem it will help ur jeep run better
