2014 Sunseeker relay problems

[BIGBOO]

I have a chevy 4500 w ith the 6.0 ,from time to time it wont start.traced it to relays in the engine compartment anybody else having this problem

[El Chapo]

Yes, and after much time and testing, found out the same as you. I've replaced Crank Relay twice, Pump Relay once, and another (Start Relay?) once. They all use the same relay, so I switch them out to test them and carry at least 5 spares. No problems in 10 months now.

I also have a 2014 Sunseeker on the Chevrolet 4500 with the 6.0 (2500TS)

Love the engine, not the electronics.

Same engine same problem from time to time, also had a fuel pump problem wouldn’t pump, replaced that relay also, been fine so far knock on wood. Also GM has now changed manufacture of that relay, I asked the part guy he said they had a lot of problems with that relay, he said not so much anymore since the change. The electronics are weird. My ABS light will come on when started, they told me to restart the engine to clear it, dumb but it works, it’s even posted in the manual to do that. I like the 6.0 but cheap parts

Hum… no start. I had that happen once. But then it did.

I thank you folks for the knowledge. I am a Ford guy loving the ride of my 4500 down the road.
