Hot car won’t run or start

[*NAT@]

So my car starts fine when it’s the first time of the day...
Stop at shops and try to start it cranks but doesn’t want to start!
Sometimes it stalls on my when trying to takeoff and I notice I don’t have the power I did have when driving just to pickup and over take I’m really pushing to get the power out of her that I never had to push for before!
Recently we have done
02 sensors
Throttle body
Plugs and leads
Service

only thing I can think of is fuel pump??? It’s gone from once a week to not being able to drive my car if I’m going to need to turn it off at some point that day and re start it.

Always check the purge solenoid.
It allows all the vapor from the hot fuel tank on a hot day fill the intake and screws the mixture.

It's cheap and takes seconds to test.

Crank angle sensor or weak starter motor.

Crank Angle Sensor. Cool it down with some cold water over it and sometimes starts.

Had the same problem when I bought the car 3 years ago. Turned out I needed a bigger (higher CCA) heavy duty battery and naver had the problem since.

Last time this happened to me was crank angle sensor. Would run fine in the morning, and fine in the evening, but if I stopped to get fuel on the way to work, game over.

For those wondering the Crank sensor is next to the exhaust manifold on the drivers side toward the firewall.

What a great place for something sensitive to heat.
