After installing my built engine the truck would run fine untill it started warming up. its like some one flicks a switch on and off. and no codes. The eng seems to shut off and back on. Its violent. The longer it runs the more it does it. I did the larger oil pump upgrade front cover and piston squirtters. It used the same electronics as engine removed. I thought it might be the crnk sensor distance from reluctor. I pulle out the sensor today and stupidly guessed at it. looked like about 1/8 inch . so i took about 1/16th off put her in. now it starts runs like shit for a bout 20 seconds and dies. lol whats a proper spacing? pulled sensor back out and it did not hit (no marks) What say you?
