Air cleaner swap, truck won't start

[Vulcan]

New to the forum and glad to see you're out here.
Swapped out my K&N filter with a new one they gave me under their warranty. There was no problem with the old one other than some little cracks around the rubber. Disconnected the Mass Air Flow Sensor and the upper part of the air cleaner housing to clean the housing. I used PB blaster to get some gasket residue of the lip of the housing with the MAF sensor attached careful not to spray toward the sensor. When I put it all back together, I go to start in and... nothing, just a click.
What did I do? Is there a way to test the MAF w/o the engine running?
By the way this would be the only engine problem I have had other than an idler pulley in 180,000+ miles of ownership. Just a great engine.

it would crank if the maf had an issue, the click is generally from a lack of power either a bad battery or battery cable, or a bad ground wire or ground connection, I think it's just a coincidence that it happened after the filter change.

Yep definately a battery or connection issue. You may want to check the engine ground as it can get neglected by being out of sight and not normally checked.

my girlfreinds jeep did the same thing, it turned out the starter solinoid randomly went out at the same time...had me confused for like 4 days

Tap the starter with a hammer. TAP don't beat. Then try again. Sometimes that will free up a sticky starter.

Negative battery cable on mine looked great, but it was badly corroded under the insulation...replaced it...starter works great...just saying...

I think you're right but I hate coincidences. I kept thinking how I could fouled up the swapping the air filter.

If anyone is still interested, it turned out that I had my transmission in Park enough to hold the truck on a hill but not enough to let the system recognize that it was in Park. Did not think to try starting it in Neutral. Minus 50 man points.
