I get a check engine light and next thing the truck will not start when cold. Just cranks over and not light-off. If I shoot some ether into the air cleaner I can get it to start after a few attempts and using NO throttle to start and it will not take throttle until warmed up a few mins.I do have a check engine light on. I downloaded what I thought was the engine coolant sensor morse code....its hard to tell but appeared to be the code. Replace the sensor at 29.00:( and still have the no start problem.

Thoughts, ideas, solutions??..

1991 3.0 6cyl. gas, auto, 4dr.
