I have a 95 ford courier 2.6l efi and it just won't start in the mornings when around 10-15 degrees it cranks and every now and then it will fire once and then won't fire at all. 2 mornings in a row I've sat it in the sun bonnet up and after about 1-2 hours it will fire and run first kick of the key. I've replaced plugs, fuel filter, air filter.

check your asd relay or fuel pump relay

so where is the shut off reset for the fuel pump on the 91 explorer? does anyone really know?

because you said it sounds like timing problems i may have an idea. i dont remeber if these have a distributer? but its common for the distributer on the newer GM trucks and i dont know why but its like the spark jumps around inside causing incorrect firing order when trying to start and just gets worse and worse. remove and inspect for build on on rotor and tabs on distributer.

and get back to me with problem
plz rate

hes right check the ignition control module.i had to replace mine because my cavalier would start fine one minute and the next it would be idling rough and backfiring. your best bet is to replace the control module.

Hello carol...from the symptons you describe more than likely it's the CPS (crankshaft position sensor.)
The CPS is a common problem on Cateras with these symptoms.
The sensor is a magnetic impulse type that sends a signal to the computer, the computer then triggers the fire signal. When the CPS gets weak, dirty or has low voltage the intermitten no starts occur. It will finally result in a no start at all...Please be aware that a lot of caddy dealers will and have overcharged customers for this common problem by ill advise and replaceing uneeded componets.
Good luck...i hope this helps and will fixya up.
