I have a 90-91 B2600I and it starts great on a warm morning but if it's even in the 60's, you have to turn the key for 2-3 seconds about 4-5 times and then the truck cranks and runs like a champ. What gives?? Someone had mentioned maybe unplugging the air sensor and cleaning the contacts but I don't know what to do? Could this be the water/coolant temp sensor?
Thanks
