      When I put gas in my car, of any amount, it will not turn over without me pumping the gas pedal several times. Once it does start, I have to rev it at about 2000-3000 rpms for 2 or 3 minutes straight to keep it from dying on me again.

      The vehicle is a 2000 Volkswagen Jetta. I’ve had this problem for some time now, and I’ve got no idea what it could possibly be.

        Put gas into it leave gas cap off and then try to start it. If it now starts better at all its problem with evap canister and/or solenoid. Doing that will give you code so keep that in mind if you or somebody else is trying to diagnose it with scanner.

        Read fault codes you will need vag-specific scanner.

        After putting gas try blocking evap hose to valve body (gas cap off) when trying to start. If it was problem with evap canister and/or solenoid it will now start fine.

          It does sound like an evap issue. Do you have any check engine light codes? If so, you might start with those. Evap testing can be tricky and often requires the use of a smoke machine to help you identify leaks. A bidirectional scan tool is also helpful to activate solenoids and such during diagnosis. Having the service procedure for the evap testing is also helpful. More information in this article on evap diagnosis.

              I went to the auto parts store today to get my engine codes read, and here were the results of what was read.

              He didn’t give me the exact codes for everything, just told me what the codes said.
              Idle air control valve problem
              MAF sensor was not working properly
              Bank 1 system 2 lane catalytic converter
              And code P1582 (wasn’t in the code reader) Google shows P1582 as Idle Adaptation at limit.

              I also mentioned this problem to the guy checking the codes, and he mentioned it could be the EVAP valve or EVAP canister.

                That’s really not helpful information and I don’t believe any of it pertains to your problem except the EVAP code. Thing is, there are a lot of evap codes. Knowing the specific code will help you track down the source of the problem. You might get the codes reread and this time write down the actual codes so we can help you figure it out.

                  Okay that makes sense. The guy didn’t tell me the specific codes, but I’ll go back and have him tell me the code number with it too.

                  Thanks for the info.

                    Okay so I went back and got the actual code numbers.

                    There were 5 of them

                    P1582 – Idle Adaptation at limit
                    P0507 – Idle Air Control System RPM Higher Than Expected – Guy at Orielly’s told me this was related to MAF
                    P0102 – Mass Air Flow Circuit low input (A new MAF is in the mail)
                    P0171 – Fuel System too lean (bank 1) O2 sensor (Getting that fixed this weekend)
                    P0422 – Main Catalyst Efficiency Below Threshold (Bank 1) – Guy at Orielly’s told me this was related to O2 sensor

                      Thanks for posting those codes. Let us know how it acts after you install the MAF. If that is indeed the issue, then the other codes may not come back after you install the new MAF and clear the codes.
