I have a 96 silverado 150k. 5.7 c1500. It starts and idles fine. When I accelerate it sputter and backfires. I replaced maf sensor. I'm stumped... any suggestions would b very helpful thanks

 

Have you checked the fuel filter and pump?

 

No I haven't. U know where those r located? How can I tell if there bad?

 

Pump is in the fuel tank. Filter is under the truck in the fuel line. You can't miss it. To find out about the pump you will have to do a pressure test.

 

Thanks. How do I go about getting pressure checked. Don't have money to bring to mechanic just rather do it my self. Is there something I can buy?

 

Well, I don't know where you are located, but some parts stores offer free loaner tools. Not totally familar with your truck, but suspect on the fuel rail should be a schrader valve to plug a gauge in to check the fuel pressure. I am thinking the pressure should be around 50-60 psig.

 

Now when I check it is there going to b gas leaking everywhere?

 

This should be a test port, plug in, turn on key, observe pressure
