2004 MT coupe on rear jack stands, now wont start.
 

Car was lowered with just springs by previous owner. The rear camber was too far off for me. Ate through a brand new set of falkens in 6 months. I decided to change the rear camber and toe arms so i can get the alignment right. So i got the parts in , put the car up on jacks ... just the rear... on wednesday. I changed the right side, was late decided to finish the driver side on thursday. Well, on Thursday i got tickets to Cowboys game , then friday went to highschool game, saturday slept and got ereaady for dove season , then went dove hunting sunday and monday.. SO, i finally got back to install the arms on the drives side monday night.
2 things.
1. After i got the wheels back on and the car on the ground, I tried to start for a test drive and the engine cranks but wont fire up.
2. The right side is about 1/2in to 1in higher than the left? not sure what happened. i just adjusted the new arms to the same size as the factory. I was planning on going straight to get alignment done today regardless, but wont start.

Any thought on these two issues would be appreciated.

You sure it is not just a battery and you probably left one of the doors or lights on. Check to make sure the battery is testing fine and go from there.

battery is fine .. lights and everything works. The engine does crank, just wont fire up.

Could be a security system issue? Unhook the battery for an hour and book it back up see if that helps

some cars do have like a 15 degree tilt failsafe in the alarm... not sure if ours do or not though... id unhook the battery too

Are you sure you didn't pinch a fuel line while jacking the car up?

jus cus the lights works doesn't mean car will start

jumpstart the battery or charge it overnight until fully charged...

I've heard that once the batt goes below 12v its considered no good. True?

A healthy and charged battery should read around 12.6v at rest. Although a voltage test alone is not enough to properly test a battery, it needs to be tested under a load by an auto parts store.
