03 Cavalier won't start - Please help...

[kylerousseau]

I forgot it running, it ran out of gas and sat until the battery went dead with the key in the "on" position. Now it won't start. Security light, check gauges and service lights all stay on. Gas gauge doesn't register any gas (I put 4 gallons in). Very little gas pressure. Has power to the ICM. No power to fuel pump. Any ideas? Thanks.

The "Check Gages" and "Service Engine" lights will normally stay on until the engine is running. The "Security" light should turn on for about five seconds, then turn off if the door is closed.

You need to establish 37 PSIG of fuel pressure before anything good will happen. If the battery is not fully charged, fuel pump voltage can be reduced and fuel pressure may not be adequate.
