I was driving yesterday and the truck died, it was extremely cold out but the truck had been running for at least half an hour. Could not get it restarted. It cranks but won't turn over. I had the tow truck driver drop it in my heated garage added a bottle of dry gas, swapped a new ignition coil. Wouldn't start. Finally started 2 days later. Drive fine yesterday after sitting in heated garage for 2 days. Woke up this morning and won't start After I left it sitting outside last night. Extremely cold this morning as well. It cranks but won't start, I sprayed starter fluid into throttle body and still won't start. Any ideas?

Have you checked fuel pressure? Or possibly your ignition control module could be bad.

By spraying starter fluid into the throttle body with no effect usually means that the problem is ignition and not fuel related. Check the crank sensor. Age and heat make them go bad.

Where is the sensor on a 5.7l vortec?
