I have a 1994 E150 conv. van that runs good, but now that it is colder I have a problem. I have changed the throttle position sensor, and still have a problem with cold start. It runs fine after a couple mins. warm up. Help! PS: It idles too low upon starting in cold weather.

check fuel pressure when it dies you may have a pump going

New fuel pump. Just does not fast idle at start. Does not shut off.
