Default read the sticky on grounds

i read all i can find and it's time to get help,
after a drive line R&R the car would not start.indicators were low oil level on display ,no fuel pressure but could hear pump,no codes.ran it down to the ground wire behind the left head was broken.re-grounded the fuel pressure sender i use for pressure gage.started and ran a few times without issue.then after a run ,on stands to 180* or so it died. restarted Sunday,ran for a while and will not start again.charger has stayed on,no codes ,good fuel pressure.no spark to wires.
i have the service manuals but no tech 2.not much help.it has to be something simple,i even loaded and unloaded the tune and that worked fine.scanned with on board,autoxray and diablo u7193.i even have a data log i ran to fix a o2 sensor .

I remember reading somewhere that there is a ground for the coils on the back of the engine possibly on the driver's side?

When I swapped out my diff for 3:42's I had an issue with the ground in the left rear wheel well. It set off like 12 codes and ran like crap. Check that. Also, when I had lowered my driveline/back end of motor so much to get the TT out that the accordian tube on my intake had come loose causing a rough idle and dying.

Good Luck
