I have a "86 GMC 3500 Rally Van withe the 6.2. Can anyone tell me if there is an easy way to change the front two Glow plugs on the Drivers side. I am exp some real hard starting problems whenit sits for awhile. black smoke rolls out the back when it does fire but seems to run just fine after it fires. Sometimes it will start nearly immediatly then quit.
I will have to crank on it for quite awhile before it starts. Engine deosn't heat up. Oil presure is good and it charges fine. Any help will be appreciated.
