After about 5 years idle in the garage not having the engine started.
I changed oil, replaced fuel filter, replaced battery and
added octane booster to the about 25 gallons of 5 year old gasoline.
The engine started, ran for about 5 minutes then stopped, unable to restart. While it idled it sounded great. Engine turns over fine, but won't start. I heard no pings or knocks before the engine stopped.
I put some gas down the carb and the engine did start very briefly. I checked the fuel pump(I could hear it whine when someone turned the ignition key on) so I believe it works. The engine is fuel injected. All parts are factory specified, no modifications.

Please help me start my Suburban that is too nice to be a clunker.

The fuel pump might be coming on but is it producing the corrrect fuel pressure and are the injectors pulsing-check the fuel pressure and get back with the readings we start here.........................
