Gents (& ladies,) recently bought my 1st 6.5L. It’s a ‘95 w/152k mikes and is a pretty clean unit. Very tight, was well maintained. After starting it and running for several seconds I put it in gear and as I was getting ready to caress the accelerator it died. I am familiar with the fuel filter priming issue of a Duramax (have an ‘07 LBZ with 355k miles) & familiar with hard to find fusible links in a ‘93 D250 w/Cummins. So all this said, I’ve been reading and watching uTube vids on this 6.5L’s issue. These are my symptoms: Engine Service Light is on, the glow plug light goes off after 4-5 seconds, then engine turns over easily, batteries are new. Previously it has started effortlessly shortly after glow plug light goes off and I turn to start. I’ve cked all fuses and also shined up their terminal legs. I have 12v at driver side terminal of Glow Plug relay/controller. Now a specific question, as I’m not remembering, once the relay turns on is the 12v supposed to remain on the adjacent terminal or should it go away after about 4 seconds? (Seems same amount of time the dash glow plug light goes off.) I’ve pulled the two fusible links up and visually inspected them but haven’t ck’ed resistance yet. I was told the fuel filter was chged out just prior to my purchase and it has a garage’s sticker indicating such. If it was my Duramax I’d get out and bleed& prime the filter. And away I’d go. But hasn’t been as quick with the 6.5L TD. Your thoughts and troubleshooting ideas are appreciated!
