Hi All,

Hoping you can lend me some of your expertise. I have a 93NA with a VVT swap and a Reverant built MS3. The car has run for years and just the other day it died while idling and wouldn't start when I crank it.

I noticed the RPM needle doesn't jump when I crank. I hooked up Tunerstudio and on the gauge dashboard it says "Not RPM Synced" in red. My initial thoughts based on searching was to check the gap on the crank angle sensor. I bought and installed a new one and that didn't work either. Could it be a cam sensor issue? I was checking wires throughout the engine bay and none of them looked damaged or anything either.

Attached is my tune and composite log, hopefully i recorded it correctly. Please let me know if anyone has any advice, much appreciated!

 

I would suspect the cam sensor over anything else for a vvt motor, either the sensor goes, or the connector to the sensor goes. Mine specifically came loose and I had to zip tie it to the sensor to fix a sync loss issue I had. I can't seem to open the .csv file to check but look for that. Some also directly connect the 3 wires to the 3 pins on the sensor once the sensor is a known good one to fix their issues.

 

Thanks HowPrayGame, you were right - cam sensor had died. Thanks so much! Car runs =D
