97 lumina won't crank and start, has power, and if I jump the starter it runs for 2 sec then dies?

An immobiliser issue I reckon. Can be really difficult to fix.

Go to youtube watch GM anti theft bypass !

You need a new battery-
It takes a great deal more power to crank a motor than it does to light up the lights. This is why your lights still come on even though the battery does not have enough power crank the engine over. If you install a new battery keep an eye on it...if it dies quickly then you have a bad alternator.

I would say if the car stays running after u jumped started it I would replace the battery

I would check the starter for voltage first - there is a starter relay that is grounded by the PCM. If the ASD relay is faulty the pcm won't have power. You should have battery power to the starter and power on the solenoid when you turn the key to start.

first you half to determine if the alternater is working. you do his by jumping the car and while its running take of the neg cable off to the car if it dies then you know the alternater is not working properly,
if it stays running you know you have a electricalen short you half to trace down

First of all have your battery tested to make sure its in good condition. Take a look underneath at the starter and make sure all the bolts are tight and secured. You may end up replacing the starter

You are reading this wrong...solenoids don't turn. They activate the starter...that turns. Check your battery connections and battery/charging system. The starter requires far more power than anything else in the car, so those items working won't tell you much.

It is one of 2 things fuel pump or Crank Shaft Position Sensor. Best bet would be the Crank Shaft Sensor, and what that does is tell the computer where the crank is and when to fire the right plug at the right time
