Chevy colorado cannot remove gas cap. Running low on fuel.

On my 2005 Chevy Colorado fuaceel filter is located on the drivers side front edge of the gas tank you can't miss it it's got the fuel lines running into it and out of it and they have pressure fittiings on them so there pretty easy to replace

Seam like transmission fluid is low.
-Start the engine, let it run for 10 minutes to normal temperature . Do not turn it off and check transmission fluid. If it's low add more fluid to full indicator. And try again.


Good Luck

hope it helps

Trouble Code: P0171

Fuel Trim Too Lean

Possible Causes:


The current cell can be observed using a scan tool.The system will go lean if an injector is not providing enough fuel.A lean condition could be present during high fuel demand due to a fuel pump not pumping enough fuel, plugged fuel filter or a restricted fuel line.Insufficient fuel in the tank or low fuel pressure may cause this DTC to set. Refer to Fuel System Diagnosis .Review the Failure Records with a scan tool. If an intermittent condition is suspected, refer to Intermittent Conditions .

Have u replaced the fuel cap? They do go bad often. Other then that you are probably having a issue with your vent valve, most common thing I've seen on all Chevy trucks..

Do a pressure check from the fuel rail. It could be your pressure regulator starting to go bad. Is normal for Chevy and GM.

Code P0455 means there is a vapor leak in the fuel system, this could be a bad vent valve, a abd purge valve, a charcoal cansistor, gas cap or even one of the lines. this requires a scan tool and a smoke machine to find the leak. but in most cases it is just a gas cap. take off the gas cap and look at the rubber seal, if the seal has small cracks, or the rubber seals looks like it is worn. try replacing the gas cap and clear codes and see what happens

You have other EVAP System issues

The Gas Cap, being okey would turn off the light

If all it was is that you did have it off it will reset by the 3rd drive cycle. It may take between 50 & 200 miles.

do you have gas? check for fuel pressure, when did this start? how many miles? did you do any work on it?
