I am about to push this car off a bridge. I can't figure out what the hell is wrong with this car at all. The fuel pump primes but when I turn the key nothing happens. I changed the battery, checked the fuses, got the starter checked out and its fine. I can push start it and it runs just fine. Car is a 98 Integra LS/VTEC.

 

Have you checked for 12v to the starter?
Also check the small wire at the starter for 12v with the ignition turn to start.

 

Got the 12v to the starter

The small wire is only getting 4-5v.

 

This is the flow sequence of the starter system.

1. 12v at Battery to...
2. 12v after 50A Fuse in main fuse box in engine bay to...
3. 12v on Battary side of Ignition.
4. 12v from Ignition switch to the starter (small wire on starter) with the ignition in the start position.
5. 12v straight from the battery to starter (big wire on starter).
6. Check the ground from the tranny bracket to the chassis for good contact and no corrosion.

That's it! If you had the starter, the battery and the fuses checked...then I'm leaning towards a ignition switch going bad.
