Re: Ard start when engine hot

Your truck is a gmt400(88-98 style). You'd have better luck in the 88-98 section


Most likely you have a leaking fuel pressure regulator or leaking injectors. Very common problem on the Vortec 454.


Motors can fail at 10,000 or 500,000. All depends on maintenance and the deck you're dealt.
