2005 Malibu classic 2.2l drive fine and just quits. Now it cranks over but dose even act like it wants to start. Fuel has pressure at the valve, the timing chain is good, I am looking up how to test the ign. Can someone point me in the right direction.
New here and need help

I have good spark, can’t find my pressure gauge but it’s got pressure at the fuel rail. It’s was running fine driving down the highway and it just stoped running. The lights and everything else worked until the flashers ran the battery dead. I tried to use a obd2 scanner and didn’t get anything after I charged the battery, I figured because the battery died it may have cleared the codes? I am thinking the pump is not putting out the pressure, the theft lock wouldn’t come on when it was running? Going to check the injector pulse next
I just tried using starting fluid to get it to fire but that didn’t work. When i crank the motor over it dose not sound right. It sounds like it isn’t turning the cams with no compression but I took off the cam cover and the chain was turning both cams and it felt like it was tensioned correct but I pulled the whole coil pack and pulled the plugs from the head put them in the coil pack with it upside down and turned the motor and it had great spark
Ok I did a compression test and it has nothing #1 30lb. #2 0lb. #3 and #4 about the same so I pushed down on the timing chain between the two cam gears and I got almost an inch of slack. I am thinking that the tensioner is bad and it jumped out of time. But it was driving under power at the time The chain should of been tight enough that it couldn’t slip a tooth ? I guess there isn’t a way to replace it and time it right with out pulling the cover at least to see the mark on the crankshaft gear?
Ok I installed the balance chain, guides , sprockets, tensioner. Everything went well no problems. I did the timing all the marks were lined up the cam loos was in the right spot. I put the compression gauge in the #1hole and turned the motor over by hand. I figured I would turn it over a couple of times, got nothing and I tryied to get to marks to line up again and after turning it 5 min. They still never lined up. They got close a few times. Do I need to crank the motor with the starter to get compression( I never tried to do it by hand before) and do the marks ever line back up I figured they would every so many turns. I double check the marks 2 times before I tried to reed the compression just to be sure. I replaced a piston on my sister Saturn a few years back with the same motor and had no problems resetting the timming. Any help

Were the tensioners applying pressure to the chain when you turned over the engine? You are sure you have no bent valves?
I turned it by hand from the crankshaft bolt. I more question, when every thing is lined up all the links in the right spot 10 o’clock a at 2 o’clock the crankshaft key at 12 o’clock and the dot and colored link at 5 o’clock, it sets the motor at the top of the exhaust stroke and not the top of the compression stroke
