What's up guys, long time I haven't posted. I recently purchased a silver 2002 GS300. It has had a few issues, all of which I've been able to solve, but this one has me looking online for answers.
Everytime I fuel up, the car won't start. It takes about 3 or 4 tries, while flooring the gas pedal. Has any one had this issue before? I'm thinking fuel pump or fuel filter? Thanks for any input.

Maybe this will help, specifically 1E - 1H.

it could be fuel related holmes or it might be the TPS or TCM going.

Thanks for the replies. @Wbmx1981, that guide is super helpful. Will try it tomorrow.

I had this exact problem on my GS430. Turned out to be the vacuum switching valve (VSV) in the engine bay. Keeps gas fumes out the engine while fueling up. Fumes get in the crankcase while fueling and make the car stumble to start. I never got a code for it though.

There is another VSV back by the charcoal cannister but that one was fine. Hope that helps.

It's not the fuel pump I just changed mine and my car still doing the same
