i know these "no start" threads come up all the time but i cant seem to find one similar enough to mine. about a month after i bought my contour it shut off while i was driving. it eventually started back up about 10 15 minutes later and ran fine for about another month then one day it wouldnt start for about an hour. then it ran fine for about 2 wks then did the same thing again. it eventually came down to it shuting off and not starting every day untill i eventually changed the spark plugs and wires. didnt help so i called ford they said it was the PCM because the overdrive light flashes before it shuts off. Replaced the PCM. Still didnt fix it so i take it to ford and tell them to just tell me everything thats wrong with it. They said the throttle cable is sticking and both oxygen sensors are bad. Got that stuff fixed and it ran good for about 2 or 3 weeks and its doing it again(shutting off while driving and not starting for awhile). This is really pissing me off. I have an amp hooked up with a 20 amp fuse. could the amp be screwing up sumthin electrical. Oh i did notice when im heavy on the gas that my battery light comes on untill i slow down. could there be a voltage drop somewhere? maybe a short in the wiring harness? im gonna check my ground wires later.
