Toyota Corona Problems.

[terranceeriley]

A Friend of mine recently bought a 1982 Toyota Corona XX for $150.
Only problem is when it gets warm it surges and then eventually stalls.
It has the 21-RC engine in it.
fuel pump has been replaced and so has teh col and leads and that.
Help anyone?

Vapor lock? When it cools down again does it re-start like it should?

Yeah it does. i will surge and stall and that and then it will start up great. when its cold it starts great and then just as it gets warm it sh!ts itself. What shall we do?

Look @ the sight glass on the side of the float bowl to verify fuel level, if you are very low or empty then backtrack to find your fuel delivery problem. That car is old enough to vote & buy liquor so the first thing that I would check is the float needle. Quite often twenty year old toyota fuel tanks have filth in them, and twenty year old fuel filters sometimes let that debris pass. It os not take a very big chunk of rust to keep your floatbowl from filling fast enough to run the engine. You could have a vaporlock on your hands but in my experience dirt restriction happens far more often, and vaporlock happens from poor heat control. Isn't it winter where you are now?

Will check the float bowl this afternoon...
How exactly would one combat a vapourlock anyway?
It's middle of winter here too....
Also, here, i'm old enough to vote and drink liquor...
ah. the joys of being 18 eh.
thanks for all the help too.

Vaporlock happens when your fuel line gets warm enough for the fuel to begin to evaporate in the line, or in the case of a mechanical pump that is pulling fuel up to the engine a pinhole in the supply line allows bubbles to form in the line. These bubbles can "vaporlock" the fuel pump if it is old and weak enough to not prime easily.
