Please help, my truck is not starting. It was running good til it cut out at a stop sign. Things I check: there's fuel going into the thottle body, the engine is turning, but no spark. There is power going to the coil. I replaced the coil and the control module pass the test. Tested the module 7 times and passed 7 times with a module tester. I checked the resistance on the pick up coil inside the distributor and it's in respectable range. Checked for for short on the distributor and it's all good. My only guess would the distributor it self -- the whole deal. Here the wierd thing, it started twice since it went out. It just ran for less than 15 seconds.
