Last time it was the battery I just installed a new one, I think the battery might be why it won't start again. It is throwing a code for Crankshaft position sensor which I heard we have 3 of. I did a search but came up with nothing that can really help me.

 

whats the OBD-2 code you are getting. a low battery won't trigger a sensor error

 

I got engine crankshaft position sensor and misfire in 2 and 4.

which sensor controls this so I can just buy one and install it.

Today it started fine but it kept misfiring

which sparkplugs are good for a supercharged S2K?

 

look up the P0xxx codes in the helm manual and begin the troubleshooting proceedure.

 

p0336 - crankshaft position sensor range/performance

I don't have the tools to check the if the sensor is bad or if which one is bad.

 

www.helminc.com for the factory service manual.

but if you don't have the tools looks like you'll be taking it to the dealer and paying several hundred $ for repairs.

 

What modifications have you done to the vehicle's electircal system?

 

I had a low battery and had all kinds of phantom errors. When I reset the ECU they all went away.

 

underbody LED kit and some speakers in the trunk but the speakers in the trunk have been gone for about a 6 months now.

And my boost guage.

 

Any chance that you nicked something under there when you did the LEDs?
