hey guys i have a starting problem on my sc400.when ever i start it on a hot day the car starts and runs for a few seconds and than it just dies, i was wondering if there is a simple part that is doing this. i have checked the fuel pump and what not and they seem fine although i do think i am look ing at the wrong places. any advice would be nice, thanks

 

fuel pump ecu most likely. There are many threads on this/like this.
