I know that the most common solution implemented to correct heat soak (the issue in which injectors 3 and/or 4 going into vapor lock when the car is shut off for 5 to 30 minutes while warm, then started) is to install a fan timer, which is not a bad solution... But in all honesty, I'm now more interested in diagnosing the source of the pressure loss that allows vapor lock to occur.
I've been doing some research and it seems as though this is what I'll want to do:
I've been doing some research and it seems as though this is what I'll want to do:
- Check the fuel pressure on the fuel rail after a solid drive and monitor for pressure loss... Just a general way to make sure there is even an issue.
- Remove the fuel rail, but keep all injectors connected. Turn the ignition to "On" to engage the fuel pump and look for any visible leaks (derp!). Somewhat dangerous due to the presence of gasoline, but seemingly manageable so long as I'm not a moron.
- If no injectors are visibly leaking, inspect the fuel line all the way back to the gas tank.
- If no line leaks are visible, drop the gas tank and replace the fuel pump check valve (is that even the right word?).
