Customer Question
only when it is hot...
I have been having a vapor lock problem with my 96 2.7L Tacoma, only when it is hot outside doesn't do it in the winter. I have replaced the same sensor and that has never solved the problem. I can usually get it to start if I take the gas cap off but that only works some of the time.

Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
The problem you are describing is very likely caused by a failing fuel pump, this type of problem will show up in warmer weather because the fuel pump will over heat and when this happens it causes the fuel to foam and the pressure will drop. You can verify this by installing a fuel pressure gauge to the fuel system and monitor the fuel pressure while the problem is occurring. Normal fuel pressure should be right at 31 to 37 PSI, any thing less then 31 PSI would indicate the pump is failing.
