96-99 Chevy/GMC 3500 ?'s

The funky injector deal is found in the small block Vortec engines. The 454" uses eight regular individual injectors like anything else. Hard starting is usually the fuel pump. Leaking intake gaskets are pretty common. Mine, at 115,000 miles has had both. Not real common for starting problem to be the injectors. Could be the fuel used.

If your having to press and hold throttle to the floor to start its usually the injectors or fuel pressure regulator. Both are quite common as is the leaking intake gaskets. I know this first hand as I own a 2000 dually with a 454. And have replaced all the above. Also having worked for GM dealers for the last 32years.
