When i stopped the 1997 suburban 1500 it was running fine. i tried to start it 2 days later and it wont start. it sounds like the engine is fighting itself. it cranks then stops then cranke a little but...
check the timing and compression as this is a typical chevy senario, runs good it seems and shut off and now fights and locks up. Pull #1 plug, put into wire again and rest on exhaust manifold so electrode is very near metal, this will cause a spark. now put finger in the plug hole and crank motor, does the plug spark at the same time finger gets pushed off plug hole (compression) ? Also you can bring #1 cylinder to top ,(compression ) and remove dist cap, where the tab on rotor aims is it aiming to the plug wire in the cap that goes to the #1 spark plug. If any of this is not in line then the timing is off and you have to check. 1) timing chain and gear, 2) distributer gear on the bottom of dist which messhes with cam gear, (you can check this with cap off and try to spin or turn by hand.) And the most severe case is the cam broke, after all other checks you can pull off a valve cover and turn motor over and check all lifters for open close movement. I hope i didn't scare you . AND i also wish the easiest fix for you as well.
