Question about 1997 Chevrolet C/K 2500
My dad and brother have been trying to get this farm truck going. It has a hard time starting when it is cold. After a while of sitting after being cranked a couple times it will start up.
The GM's are notorious for losing fuel pressure,could be fuel pressure regulator,or a weak fuel pump....also check for rusted fuel lines that will lose pressure when sitting..both feed and return lines...

If you mean the compression is low this will explain your problems low compression will cause hard starting when cold. When you crank faster or longer it helps build up enough to get it started. Then when they warm up the pistons take there shape and the rings seal allowing it to run and start back up. One way to verify is to squirt a small amount of oil into each cylinder this will help to seal the rings to start it. If it starts easier then that is your problem. To fix it you will probably need to re-ring it. But first you might try to do a top engine clean to see if the rings are carboned stuck.
