Stop replacin stuf..ur guessin. The computr cud b bad..when u disconn it clears the relearn. Unplug it n clean pins..its common that its corroded n car will com back. If it has a distcap take it off n clean inside or replace. A datastream run at a nondealer mechanic tells u mor then any handheld scannr
Testimonial: "thanks to both comments I agree I was replacing a lot of stuff but I was following the problem which last night lead me to the top of the manifold in the back and bingo a mouse chewed off the wires to the "manifold absolute barometric pressure sensor!! ordered a replacement harness. thank you."

1999 Yukon Start Issue - I have replaced the octopuse, battery, fuel filter, fuel pump, still having problems starting in cold weather, sometimes after a heavy rain.
Any suggestions?
Thanks

if its running rough you should have codes stored, have you checked for them yet ??
SOURCE: i am not getting power to my fuel pump
on a lot of ford products there is a switch that goes from the fuel pump to the inside of one of the bedsides.
what this is, is a shock switch that turns the fuel pump off if it absorbs a hit.
its a really dumb safety feature but its effective.
there is a red button on it that u have to press to make it active again.
sometimes they just trip for no reason.
