[Gmecm] Re: Undignified death of a project :P

Same with TPI, LT 1 and LT4.  A relay for instant starting turned on by the 
ECM and a redundant fuel pump power supply through the oil pressure switch. 
This, however, was not to shut the engine down because of no oil pressure 
but as a back-up should the fuel pump relay fail.
