Are there any problems with the Vortec 5300 engine?

Another issue gen-three Vortec 5300 engines commonly experience is the failure of the fuel pressure regulator. This may cause the vehicle to be difficult to start or may even prevent it from starting entirely. Additionally, it can cause rough idling and stuttering, poor acceleration, and prematurely fouled spark plugs.

What is the fuel pressure on a Vortec?

Dude, 150 psi of fuel pressure is extremely high, perhaps even impossible. I would suspect your pressure gauge. Dead head pressure may reach 100 psi. These vortec engines are well known for injector/poppet valve problems, so you may want to consider the upgraded injector assembly that eliminates the poppet valves.

Why does my Chev k1500 350 Vortec backfire?

When I hear backfiring, can only think about ignition problems, with rich fuel problems and good ignition, shouldn’t backfire, but will see black smoke from the exhaust. With erratic ignition, if the spark does come, can come at any time, even the wrong time, and if the intake valve is opened, it will backfire.

What’s the timing on a 97 Vortec 350?

Just youtube search, timing a 97 vortec 350, or 5.7l. And videos should pop up. I can tell you this though. You need a live data scan tool that can read timing, and you have to rev the engine to 1000RPS I think, then set the timing on the code reader as close to zero as you can.
