2015 GMC Sierra 2500HD SLE 4wd Crew Cab. Truck is all stock with 86,000 miles. I’m second owner & no previous problems that I’m aware of & none since I have owned it until now.
I noticed last Saturday after driving pulling skid steer to job site that when we took break for lunch that I had to hold the key in the start position for longer than normal. The temperature was 70 degrees. We went a few places and it seemed to get worse. Anyway finished the job and came come. Played with itsome at the house and at times it would not start. Read online a few things about the fuel filter head loosing prime. Next morning I tried that and it still took longer to start.Go forward to Monday morning it took about 3 try’s to get it started. Monday at lunch I primed the fuel filter head & I didn’t think the truck was going to start. Finically it did. I left it running while going into the store. That afternoon I had the batteries tested & found that one needed replaced so I replaced it there in store parking lot. All good after the truck was starting as it should no issues.
going into Tuesday (yesterday) truck done fine in the morning. It’s way colder yesterday morning & glow plug light came on I waited until it’s off then truck started fine. Lunch time truck done fine. Leaving work to run do a small excavator job truck started fine, but after Job and time to go home I turned key & truck didn’t start. I tried agin and it was 5 seconds before the starter engaged. Got home messed with it turning on and off same thing a long delay having to hold key before truck fires up. Now once starter engages it fires right up.
This morning same thing 1st try nothing all lights come on and gauges cycle then I try and nothing. I did notice the check engine light stays on while gauges go out when nothing happens. Turn key off position try agin and hold in start 3-5 seconds & truck fires up. I should note that when it starts it runs great no issues. Also, the times I have manually pumped the fuel filter head assembly it primes up hard as a rock. I have to push it anywhere from 3-5 times then it firms up.
why would the new battery fix this for one & 1/2 days then start back agin? It just don’t seem fuel related to me, but I’m no export so, looking for help on here as to where to start relays, fuel filter head etc... hopefully someone will have a fix for it. Thanks!
