Recently had fuel pump replaced at Midas on 03-24-2011. Now, the engine lite is on. Midas did not want to do a diagnostic test. So, I went to Auto Zone and here is what it reads. Evap small leak detected, ECM has detected a large leak in the EVAP system Probable cause: #1defective, loose or missing fuel cap #2EVAP canister broke, hose cracked or not connected #3Purge or vent solenoid defective #4Vacuum leak at engine. Is this something that could have been missed while replacing fuel pump? My Fuel Cap is on.

Depending on where you end up finding the vaccum leak, it's possible it was caused during fuel pump replacement. #1 cause is the easy simple fix, but you need to find out if the leak is on the vent tube to the fuel tank if so Midas should fix it for free. If it is from the EVAP canister, engine, purge valve bad, this may be just something that happened near this repair, but not related. The fastest way to find this type of leak is to have a smoke test done. It may just be a crack in a vaccum hose. with a smoke test it can be found in a few minutes. Other tests may take hours to complete.

the pump module is internal and has to be removed from the tank. there is a gasket that seals the module and yes, it is connected to the work. if the light was not on before the repair, then it makes sense that they may have overlooked something on the repair. if they wont recheck there work, go somewhere else and have it checked. if it is related, go back to midas and tell them and get re imbursed for the diag and tell them to repair it correstly. We all make mistakes and when we do, we have to stand behind our work no matter what the cost. Roy

No the engine light was not on. I know we all make mistakes I just wanted him to check it out. But, I couldnt even explain when he put his hands up to stop me from talking and said that would be another diagnostic check $95.00. I dont see why if they are the only ones that touched the car. I was not even upset. I just wanted to ask can you please check it out. Thank you!
