Bought a military customized 1997 K3500 crew cab. Some of my mechanics refer to it as a Chevy and others refer to it as a GMC. Is there a way to find out which it is ? Also .... Has anyone else experienced the following symptom: Everytime I try to start my truck (warm, cold, wet or dry) it always fails the first time (cranks but doesn't turn over). However, it always
starts the second time I crank it and runs like a dream. I've had all the ignition wiring, plugs, and distributor cap replaced but still no luck.
