"When filling with fuel the car does not start without mashing the pedal while cranking" So on a modern day car "mashing the pedal (throttle) just gives the engine more air. The DME/ECU gives the engine gas. So your fuel air mixture is to fuel rich after fueling so it will not start until you give it more air by "Mashing the Pedal" So my guess is that you have an issue with the EVAP system. bad purge valve or the like. An EVAP purge valve stuck in the open position allows fuel vapors back into the intake. So it causes a to fuel rich situation after filling up. EVAP systems can be a PITA. Your stalling when coming to a stop can be caused by this same situation. or.... a vacuum leak. Have you done a vacuum test with a proper vacuum gauge??? |

With all the parts you are throwing at it, it might not be a bad idea to have a shop spend an hour or 2 doing a diagnostic on it so you can replace only what is necessary to fix the issue. Been down this route with other cars. Sometimes it is a good idea to take a step back and have another set of eyes on an issue vs replacing parts that may not even be the issue.
I suspect you have a vacuum leak and/or an issue with a ground wire or wiring issue somewhere |

Smoke tests cannot test vacuum on the down stream side of a one-way vacuum operated valve. Such as the one in the SAI system. So for example a smoke test would not detect a vacuum leak in the SAI vacuum canister. A vacuum gauge only costs around $20.00-$25.00 Anyone who tinkers with cars should have one and know how to use it. They are a very useful diagnostic tool. |
