Drove my car to work one day and drove home. Next morning went to drive it to work again but, wouldn't start. Have replace coil module and spark plugs due to 1,3 having low visible spark. Still no start. Checked timing and appeared to have jumped upper chain 7 teeth. Installed new timing kit and set timing for upper and lower timing chains. Still no start. I'm confused about this. Is there anyone who might know what's going on? Please help. I'm borrowing bosses truck, so really need my car running.

Replaced starter, tps sensor, plugs, ign mod, coil, fuel filter, ckp sensor, ckd bat, cleaned fuel pressure reg, ckd timing chain. Still wont start almost eith gas pedal to floor help

New fuel pump new plugs new plug wires new coil packs. Will turn over but will not fire. Any suggestions??

I dont know how to tell if its my timing chain or my coil pack

I can hear it trying to start but it wont turn all the way over i was thinking coil pack but not 100 %

Starts fine sounds smooth. The minute it warms up it misses sputters stall dies. Have to double foot it to get it home. Let it cool off rand repeats all over again. I have replace all the sensors two new brains new cool packs new plugs and wires ran injector cleaner through it sea foam through it i'm ready to scream. One day it started acting up like this nothing traumatic happened to the car. Super frustrated. I read on a blog that where the computer is grounded under the coil packs sometimes the harness look like they are connected but here not getting enough connection they were all right. Any suggestions ? Help

My 03 Cavalier only starts if I hold gas to the floor and let up when fires -Sometimes it idles but most times it's iratic checked spark and it looks like it's going backwards into the coil ?

Last Monday I got in my car started it and drive 1.5 miles home. It was very loud pulled in my parking lot parked, and turned key off. Waited bout an hour went out and checked my oil and to my surprise there wasn't any registering. I added 2qts and started it waited 10 minutes for car to warm up and noise starting away. Put it reverse backed 15ft changed to drive and it died. No restart. I have thus far have replaced the:
Ckp sensor
Starter
Fuel filter
Spark plugs
Fuel regulator
Coil above spark plugs. I'm getting spark and if leave foot on pedal a minute I smell gas. I've checked the pressure and it is right. It also turns over. I am stumped
