Our Tahoe is a 1999 4door, 4x4. The engine is a 350ci, 5.7L V8 and the mileage is 104,400. According to the door label the model is K10706.
Yesterday we were driving home when the engine started to " cough" or " stutter", as if it wasn't getting fuel. My husband tried stepping on the accelerator, but there was no response. Later in the day my husband tried to start it. The engine wants to turn over, the starter is working and the battery is fully charged with clean posts. It sounds like it is not getting fuel. Stepping on the accelerator is not helpful. Again, seems like it is not getting fuel. We have experienced a week of freezing weather-unusual for our area of the country.
A little history. Last January (2006) we did a Do It Yourself replacement of the spark plug wires, spark plugs, distributor cap and rotor (at 99,000 miles). We picked up the parts at Napa Auto Parts. We had the dealer replace the serpentine belt. At 90,445 miles the dealer did the 90K service, and the fuel filter was replaced, a fuel flush was done and a new pcv valve was installed. An " engine fuel tune up" was done at 66K. We've followed the book with regard to servicing this car.
I am thinking that the fuel pump is no good, or a relay switch has failed. Perhaps the fuel line was frozen, got plugged and created a problem with the pump? At any rate, I am not sure where to begin, short of having the car towed to the dealer. If this was your car, what would you check, and in what order? And what would you be thinking as to what might be the problem?
Thanks for your help!
