Use a gage and check fuel pressure. Any applicable trouble codes? Do you have an injector pulse?

The computer pulses the injectors to spray fuel. You can use a noid lite to check. The autostore sells them.

Do different brands of spark plugs and wires fit each others and if so what is the brand to buy.

Delco is the best brand to use as it is OEM on that vehicle.

What is the correct spark plug gap for a 5.7 L gasoline engine? The recommended spark plugs are CR43TS.
