This is a new-to-me 1997 GMC Yukon/third vehicle I picked up cheap this summer. Had it in the garage to do some front end and other work the last few weeks. Been on jack stands and haven't started it for close to a month as I check things off the to-do list.
Over the weekend I replaced the in-line fuel filter under the driver's door. It went pretty well and I got everything buttoned back up. I finished another project on the truck tonight and decided it was time to start it up. The battery, as I suspected, was pretty weak and wouldn't crank the thing over. (In about 4 weeks, it's had about 8 miles put on it. The battery is an Interstate that has a date code of 10-2015 on it, FWIW.)
As I turned the key on, though, the fuel pump made an unusually loud noise for maybe 30-40 seconds before going silent. I turned the key on/off and it did this each time for 3 times over about 15 minutes. The sound reminded me of an RV water pump priming itself on the first use of a camping trip. Sort of a whirring sound that changes as it gets close to a successful prime.
So my question is this: Is the fuel pump acting abnormally because of the fuel filter swap or the weak battery?
I have the battery on the charger tonight so I guess I'll know for sure tomorrow. In the meantime, any ideas?
