From tap noise to no start

[JFITZ]

I REPLACED CHAIN TENSIONERS ON MY 2002 EXPLORER XLT DUE TO THE CLICKING NOISE FROM ENGINE. IT SEEMED TO RUN GOOD BUT VERY NOISY. NOW IT DOES NOT START. TURN KEY AND IT MAKES A SPINNING WHINE TYPE OF NOISE. ALMOST SOUNDS LIKE A STARTER DRIVE SPINNING. THE COOLING FAN DOES SPIN WHEN CRANKING IF THAT MEANS ANYTHING. ANY INPUT WOULD BE APPRECIATED.

People will need more info, engine? v6 or v8 do you have any codes? Give as much info about the vehicle as you can.

It's out of time thus getting no compression.
