Question about 1991 Cadillac DeVille
1990 deville, I have replaced the ecm, fuel pump, filters, relay..still no fuel to rail. Fuel sentry is reading 8 gals, then goes to a flashing "E".
I had same problem in my 90 deville. Drove myself crazy, I replaced the sending unit in the tank with a new fuel pump. I also had to replace the fuel pressure regulator, which sits behind the rail system. It worked for me.

Wow...BIG problem...I'd say you have a bad ECM - maybe you hooked it up "hot"? otherwise, check all grounds for secure connections.
