Anonymous Posted on Sep 25, 2010

1990 chevy silverado 1500 single cab. 180K miles. Last few days if the truck sits for 8 hours truck has a hard time starting up. Takes a good push on the gas to get running. Oil changes and fuel injection cleaner is applied every 3k miles. Once truck is running run fine at idle. Possible fouled plugs or fuel filter?

Yes sounds like the fuel filter is clogged when push gas pedal put it in clear flood mood and resets the fuel system and starts over thats why it starts when push to floor creates back pressure sucks debri bottom of filter

Testimonial: "Thank you for you timely feedback. I will replace the fuel filter ASAP. "

Yes, it is possible that the plugs are fouled or the filter is clogged, but the chances are rare. Have you noticed if the truck is more difficult to start on colder mornings or mornings when the humidity is high? Whats the trouble codes?

2005 chevy silverado 1500. Just on first start or if sits for a few hours engine will bog down. When using auto start takes a few tries

Possible fuel pump issue causing fuel to drain back into the tank. Check valve inside pump may be bad. Once vehicle is turned on it may take a few seconds to prime up the fuel lines until operating pressure is reached. Put a pressure guage on the fuel rail and start the vehicle. Should be approx 55-60lbs running. Turn off vehicle and leave it sit with guage attached and monitor for pressure dropping off to 0. If so, suspect a bad pump

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.

2007 Chevy Classic Crew Cab tried to overheat in traffic for the first time. I have 48000 miles.

Your vehicle should never over heat regardless of age. Your thermostat and radiator cap will however become tired and will need to be replaced. The coolant in your engine should also be replaced as the PH level will rise and this will eat away at your radiator.
As for your brakes squealing, they may need to be replaced. There are little springs on your front brakes that will contact your rotor and these are intended to let you know that you have 10% left.

The stepping motors in the gauges go bad. do a search on ebay for CHEVY SILVERADO INSTRUMENT CLUSTER for cheaper repair options. The dealer charges around $300.00. It will continue to worsen.
