Put the car on a flatbed for the first time during my 23k mile ownership.

Shipped it to the west coast from NYC ahead of Car Week and it no started — cranks, no tach bounce, no spark — so they had to roll it off the trailer.

Flew over a couple of days later and worked through all of the usual things I could in a friend’s driveway: swapped DME relays, FP relay, FP (runs when jumped), re-seated & checked all three sensors^ (resistance OK), harness, grounds. No dice. I keep a lot of spares in my kit but not spare sensors. Did not check AC voltage on the speed+ref when cranking as it was 95F+ out and needed to cut my losses/get the car to a shop before EOD.

Dave @ TRE made some room to take it in. Known-good DME swap didn’t do the trick so hoping for an update on Monday. Suspecting ref/speed sensors decided to give up on a hot and bumpy (enclosed) trailer across the country?
