1995 Toyota Tacoma 4 cylinder 2.4 liter
Since I've owned this first year Tacoma, it is hard to start in the summer after shutting it off 3 times in a day. No problems in the winter, no problems in the mornings, just in the heat of the afternoon in summer. If it sits an hour then no problem.
I've checked for a plugged fuel vent on the fuel pump and also changed the fuel pump, changed the air filter, new plugs, plug wires, distributor cap and rotor, oil/filter, engine ground, fuel treatment for a vapor lock situation, unscrewed the fuel cap to release pressure(?), have tried looking at the distributor, checked fuel pressure regulator, checked for flow at the fuel rail. It must be that fuel is not getting through somehow only when it's hot and I have too many short stops with engine off. I've driven it 500 miles no problem but when I shut it off on a hot summer day, I have to wait an hour for it to restart.
