2011 Chevrolet Express 1500 Problems"No start" Caused By Failed Fuel Pump
The fuel pump may fail causing the engine to stall and not restart.
The throttle position sensor (TPS) on the Chevrolet Express 1500 is notorious for failure which causes:
- Check engine light
- Reduced Power message
- OBD trouble code P2135
This issue is related to the throttle position sensor, and can be caused by faulty wiring to the TPS, bad connection at the TPS, or a failed TPS.
To correct this issue, the wiring harness, connector, and throttle position sensor must be inspected, tested, and/or replaced. The most common cause is a faulty TPS.
2011 Chevrolet Express 1500 RecallsNatural Gas Leak
Certain vehicles equipped to run on compressed natural gas are being recalled because the high pressure natural gas regulator could develop a leak, increasing the risk of a fire or explosion. Dealers will replace the natural gas regulator to correct this concern.
Certain vehicles are being recalled because if a crash were to occur not requiring deployment of the front airbags, the head of an unbelted front seat passenger could hit the instrument panel, resulting in personal injury because the panel may not sufficiently absorb the impact. As of this writing, General Motors is still working on a remedy for this concern.
Certain 2011 Express vans converted by Impco Automotive to run on compressed natural gas may have a pressure relief vent pipe which may not have been built correctly. If venting of the natural gas were to occur, this gas could end up in the passenger compartment, increasing the risk of an explosion or fire. Impco Automotive, in cooperation with General Motors will inspect the pressure relief device and vent pipe assembly and repair them as necessary.
