[QUOTE=jim hunter]could be tach issue( these vehicles can just be tachless) or what type of bypass did they use for the secur-lok key? if they placed a key in a universal box i have seen issues with ford keys not liking to freeze!either try to insulate the key in the box module, or upgrade to a keyless interface (ala i-datalink)or if you can get a ford bypass(made by codesystems for ford dealers) it has the chip encased in a gel to protect from freezing , i have used these many times and never had a cold no start issue but i have had that when a key was placed in a universal bypass[/QUOTE

No bypass problem would allow a vehicle to start and run for twenty seconds!

its also quite posible that it hasnt been exact timed,estmates of times are almost always spotty at best unless being actually timed,and i mentioned tach issue first, but the bypass interface is also another possibility for only a problem in cold weather

Either way, if a bypass was faulty, the engine should never turn over!

For everyone that helped and anyone in the future with this problem...

I fixed it last night. It WAS a tach issue. There are 2 different ways to get a tach signal, coil or injector. They had it on an injector and the RS kept sensing over-rev even though the tach was around 1k RPM at the time. I turned over-rev off on the RS and no more issues. For anyone that doesnt get that to work for them, try switching you tach signal source. Thanks again everyone.
