Im having an weird issue with my 2005 Yukon Denali. I went to start the truck and it turned slow but would not fire. Tested the battery. Was weak. Bought a new battery and installed. The parking lights would flash 8 times when the ignition was turned on, turned slow when cranking and would not start. Replaced the starter and tried to start it. The alarm went off and would not try to crank at all. I tested all fuses. All okay. Tried the alarm reset procedures I found online and nothing.
I had to have the truck for work so I removed the horn relay to shut it up then ran a jump wire from the high beam fuse to the starter relay and it cranks up and runs using the highbeam function to start it. No engine light or security light but the parking lights still flash. So I just turn on the headlights while driving.
Any idea what it could be?
