ok i have done some searching, i know the ls1 sensor has a different part number then the lt1 so they are physically different, but for the 24x swap do they send the same signal to the pcm?

 

Yes. I covered sensor compatibility among TPI/LT1/LS1 systems in my book. Available through most retail book stores (even iBooks and Kindle).

 

thanks Mike, soon as the weather here in Michigan breaks i will most likely be bugging you some more, only after i do some diagnostic at a shop that has a oscilloscope thou an if i still can't figure out my no fuel no spark issue.
