2002 C5 Z06 Should start faster than it does

Hello Everyone,

My 02 Z06 cranks for about a full second longer than I feel it should. New plugs, wires, fuel filter installed weeks ago.

Fuel pump? If yes, how do I check the pressure? Via the fuel rail end cap?

I greatly appreciate any help!

Check fuel pressure at the Schrader valve at the end of the fuel rail, you can rent a fuel pressure gauge from most auto parts store, should be around 55-60 psi.

Going to try checking the PSI at the rail and the battery. Haven’t been driving it much lately, didn’t even think of the battery.

Thanks guys
