02 2.7 Sebring no spark no codes

02 Sebring 93k Miles stalled, towed, sat at tow yard for a weekend, battery stone dead, lost memory

trickle charged battery, no start, plenty of fuel, no spark at all

when I read crank and cam, signal says lost synch

I replaced timing chain tensioner and checked timing against several different marks and timing is dead on accurate.

Unplugging sensors one at a time has not worked to start, but has caused faults when unplugged

When cranking several seconds, top vacuum line at throttle body will pop off
