Customer Question

G'day... 1998 GMC 6500 with a 3116 - cranks, unit will not start - ongoing problem for some time. I know it will not start when the check engine and intake heater light do not come on. This is intermittent, doesn't always happen.. usually runs along good for awhile, will quit occasionally. Unit sits about 8 months of the year, just used for snowplowing... love the truck, but, it's getting some irritating !
