I'm trying to diagnose a CAT 2P6000 with an intermittent cranks no start. I do not have access to any CAT info or computers. No lights come on the dash and after attempting to start enough times it will start up. This is most pronounced first start of day and is worse when its cold ambient temps. I'm a 20 year GM guy but only a 4 month forklift guy for a Yale dealer. This is a GCT , 4 cylinder engine. Any help would be appreciated.
