You Won't BELIEVE Why This Buick Doesn't Start (3-MONTH PARTS CANNON!)
We're heading West to Columbus, Ohio!
Along the way, we have a few fun Diagnostic Calls...
This 2008 Buick Lacrosse decided to randomly stall out at 68k miles.
3 MONTHS of PARTS CANNON later, and it still doesn't run!!
The entire Ignition System (ICM, Coils, wires, plugs, CKP, CMP) as well as the ECM have been replaced....YIKES!
By the way, No DTCs are set....the local shops are STUMPED.
Let's start from scratch and follow the data.
Since we have no good clues from the ECM, we're getting out the PicoScope and the PHAD Pressure Transducer to check the basics: compression, spark, and timing.
You WON'T BELIEVE what we find!!
