I need some help! B20 vtec turbo wont start

I took my car to get a tune and while it was getting tuned it went dead and wouldn't start back. It's not even turning over! The tuner instantly said,"STARTER" get a new one and come back!.....I came home and bought a brand new starter and it still won't do anything.

Dash lights all on, fuel pumps are priming...Relays and fuses are good... I can even start the engine with a skrew driver...What the hell??

Someone please help shed some light on this for me....

mine was doing the same thing the new ignition switch is like 300 bucks if you want to test the starter to see if it starts make sure it is in neutral set your park brake, turn the ignition to on position and take a piece of wire and put it against the starter solenoids connection and touch it to the power wire nut on the starter

Yeah, I read something online saying to turn the headlights on and try to start the car, if the lights dim, the ignition switch is fine, if not, it's bad...I'm on ebay pricing them right now....this sucks!

- Wed Apr 27, 2011 10:43 pm #252676 Alright....So I was wrong again. The car still won't start!

Starter is good!
Fuses are good!
Ignition is good!
Starter interlock/clutch safety switch is good!


This all happened during my tuning session. I was running fine the whole time, then the tuner turned the engine off and tried to restart it with no luck. EVERYTHING work's, dashlights and fuel pump's are working like normal but nothing happens when you turn the key... I'm trying to stay away from the idea that it's the wiring in the harness because it's been working fine all this time and then it just stopped.

Anyone have a suggestion?

- Thu Apr 28, 2011 12:07 am #252687 There is a clutch interlock relay at the side of the driver's foot well.
This relay will make contact when the clutch pedal is pushed AND the
ignition is in the start position. You can test this fairly easily:
Measure the voltage between ground and fuse # 18. Most automotive fuses
has recessed metal tabs on the front for easy access with voltmeter
probes. If the interlock system is working, you should see about 12V at
the fuse when you press the clutch and turn the ignition to start.

ALL GOOD NOW!
