Engine Mechanical problem
2003 Chevy Cavalier 4 cyl Front Wheel Drive Manual 71000 miles
----------------------------------------------------------------
My car would not start yesterday after visiting a friend's house. It just turns over but won't start. Is it a fuel pump problem, sensor, etc.? I don't have a lot of money and it is my daily driver to get to work. Plenty of gas in tank but it just put me down. It is fuel injected, maybe no fuel pressure? Please help, quickly!

you will have to check the fuel pressure with a fuel pressure gauge and check spark with a spark tester.

Is the anti theft light on?
Did you leave the keys in it?
Some cars deactivate the fuel pump if the keys are left in for too long. PCM assumes someone is trying to pick the lock so it deactivates the pump and activates the anti theft system.
Something to check before spending a lot of money.
Wouldn't hurt to rent the code reader from your local auto parts store (usually free-deposit returned).
