i have an 88 gmc k2500 with a 5.7tbi and my timing skipped
so i put in a new cam lifters and chain set. everyone that i talk to said that the timing marks should be 12 and 6 oclock. 12 on the crank sprocket and 6 o'clock on the cam sprocket. i did that and it will run but as soon as i plug in the advance timing it wont start or run. so what should i do?

i have an 88 GMC k2500 with the 5.7tbi i have tried to set the timing on it cause it jumped, i have replaced the timing chain and put a new flat tappet cam with lifters. i set the timing marks like it showed in the book and it showed that the cam sprocket is at 6 o'clock and crank sprocket is at 12 o'clock. i spun the engine over to check to see if i had the marks in the right spot and after spining the engine over to check the timing on the compression strock my marks are both at 12o'clock
