Replace the fuel filter for starters (no pun-sorry) If that doesn't help try cleaning MAF sensor with spray carb cleaner and LET DRY before reassembling (Mass Air Flow sensor) big round tube after air filter, they get dirty and gummed up.

Check all grounds. Give a good looking over under the hood and assure that everything is grounded nice and tight. I just read something about this in the last week.

Sounds like it could be a dirty or faulty idle air control valve.Take it off and clean it with a wire brush and a non-chlronated brake cleaner or replace it with a new one.Make sure you reset the computer after cleaning or replacing the valve.

I have a 1999 Chevy Silverado 1500 thats just turned over 100,000 miles. For the past few months, I sometimes have to bump the starter more than once (maybe three times) to start it. I've changed the plugs...


A common problem is if the fuel pressure regulator leaks internally. This causes fuel pressure to bleed down over time and makes it hard to start the vehicle if it has been sitting for usually more than a few hours. Sounds like that could be what you are dealing with.

I have a 1999 chevy silverado 5,3 i had the oil changed three weeks ago. now my light comes on tellin me to change my engine oil. what could cause this?


  • its a sensor that lets you know to change oil. 1st turn key on start possession don't start, 2nd pump gas pedal three times fast not real fast then after the third time turn key back to off then start the vehicle this should reset the light!!

I'd be replacing oil sender. GM have used oil pressure switch as a safety shut-off to fuel pump, when oil pressure drops off, as it would in a collision, due to engine stall.
