Ok I tried searching but found nothing. So the truck is a 1996 Chevy K1500 with the 5.7 vortec has 166k miles on it and just wont start. I tried a new fuel pump and didnt work tried a different coil and then started just fine and ran good. Two days later same thing crank no start this time had no spark so narrowing it down thought it was the crank sensor. Switched it out and ran fine for 3 days. Now this morning it happened again. Now I dont know what else to check and I'm out of ideas any help would be great. Thanks
