Engine Mechanical problem
2000 Chevy Silverado V8 Four Wheel Drive Automatic 194000 miles
Our 2000 Chevy Silverado 1500 was driven to the store (acting just fine) and when we left the store, it wouldn't idle right, very rough. It wouldn't respond to the gas pedal. We started it several times and it would idle roughly for 5 - 20 seconds before stalling. Finally, it settled into a normal idle and we took it to a repair shop.
The repair shop called us and told us that it would cost us about $1000 to replace the fuel pump and there was 'another problem too, but we'd deal with that after the fuel pump'. I insisted on knowing what the second issue was and they told me it had to do with the 'air intake system' but wouldn't get more specific.
We picked the truck up and brought it home. (Still starting badly with rough idle and stalling but we got it moving.) It stalled three times in a 20 minute drive, while the truck was moving. I followed my husband home and he would just start cruising and slowing down, trying to restart it, till he'd eventually just stop and have to sit there until we got it started again.
Tech codes from receipt:
Perform EEC test: Found P1416 air system. Check fuel pressure: 15PSI. Rec; Fuel pump, F/F.
Tech found code P1416 System Air Bank 2, Fuel Pressure 16pts at axle.
Now, possibly related (or not). My husband was run off the road by an 18-Wheeler the evening before. He was going around 50-60 mph when he was edged off the road by the Semi. Uneven dirt and mud, tall weeds, very bumpy. He's worried something may have happened then to cause these issues.
We do not have $1000 to drop on any kind of repair. We can remove the bed to get to the fuel pump if needed. But I'm not 100% convinced it's the fuel pump. If the system air bank 2 is messed up, could it cause bad idleing/stalling? Would replacing the air pump fix that?
WHERE in the vehicle is the system air bank / air pump (I'd like to look for some loose wires / loose anything).
