I had this problem last summer, if I drive for a while when hot out, it got 90* today, the car would stall but will not start untill cooled down. maybe 10 to 15 min later. The temp is where it should be and everything looks good. It did not overheat.
Has anyone had this problem? I drove the car all winter and never had any issues untill it got hot out. Could it be bad coils? cam angle sensor? Would a bad PCV valve cause this?I have no CEL so it could'nt be a sensor.
Also a weird thing with my vacumn. Before it does this my vaacumn reads 0, like nothing. what would cause the car to run no vacumn? any help would be apprieated.

 

come on guys, somone got to have the same problems, anyone?

 

realy NO one has had their car stall for no reason, not start? but later it will?

 

Have you tried a boost leak test? Kinda need more details here.

 

have not tried a boost leak test yet, I got a ix bov. drove fine all winter-spring about 7 months only does this when hot outside.

 

Thermostat read within normal temps when it dies? Does the car just stall out and die? Does it stutter? Any fluids leaking? Does this happen when you run the AC or can it happen even with it off? I'm not really sure whats going on just trying to gather some information that maybe someone else could use.

 

Temp is fine, normal. it does sputter a little then just dies. like it's not getting fuel. no fluid leak, fuel pump relay is new. and it has happened with ac on or off. some say it could be a bad Crank sensor or cam angle sensor but took it to autozone and it reads no code. even a bad coil would throw a code would'nt it? I think it might be the fuel pump overheating? I do have the pump hardwired maybe the relay I used is going bad? Going crazy trying to figure out, help

 

just off the wall, but could you be getting vapor lock in the fuel lines?

 

What causes vapor lock? how to prevent it

 

Vapor lock is more commonly with carburetors... What fuel pump do you have?

 

walbro 255.

 

Have you noticed it being a lot louder than usual? (Whining)

 

From my experience when my cam angle sensor was bad the car would not even start up. I also don't see how heat could affect it.

 

Most people have that problem with tubular manifolds that are close to the cam angle sensor...

 

it's not any louder than before. you think it coul be the coils instead? how about the crank sensor? like I stated above I get no vacumn when it gets hot also what would cause that?
it ran fine today even turned on ac to try to simulate the condition but nothing. what's up?
