2003 Silverado 1500
What is your question?
2003 Silverado 1500 intermittent starting problem. It sometimes starts as soon as your turn the key other times you have to crank it a few times before it starts. Sometimes it backfires through the throttle body. It has a new tune up new, fuel pump, new pressure regulator, new wires, but still has trouble starting sometimes ???? Any suggestions?

Hello, when I think of backfiring, for example, I think of too rich fuel going into the cylinders due to air flow or exhaust issues, or ineffective ignition components. Is it possible there's an air restriction somewhere? An engine vacuum issue? A timing issue? Hands on testing is needed to learn more. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554. We'll gladly find you a certified RepairPal shop in your area.
