I drive a 90 Ford Tempo that had a history of vapor lock when it gets really hot, like it did today (almost 40 degrees celsius.) The car died while i was driving it, but I was able to start it after a few minutes, and drive a few feet before it died again. It sort of sputtered before it died.
Does that sound like a fuel pump of just vapor lock? Like I said, this vehicle has a history of vapor lock in hot weather.

best way to tell if its your fuel pump is to get a fuel line pressure checker, and compare the reading to what ts supposed to be

Most of the time when a fuel pump goes, it doesn't start working again, and then quit again. Some fuel pumps are made to shut off if they get too hot. It's a safety feature. I'm not sure if a vehicle that old would have that feature. But it would explain why after sitting it starts again. There are a bunch of things that could cause that. I doubt it's vapor lock. You really don't see that anymore.

Could be. When was the last time you put in a new fuel filter. Low fuel pump pressure will usually make it hard to start and make you pump the pedal. A plugged filter will do the same SOMETIMES. It might also cause misfiring too.
I put 70,000 a year on my truck. Have been thru a few things over the years. That first answer was just plain BAD. The 2nd and 3rd are both good.
Try the cheap stuff 1st. If you know someone that works on his own cars ask them to walk you thru putting in the fuel filter. Do it yourself with them supervising.

Since today's cars have the fuel pumps near the gas tank or in the gas tank, I doubt if it is vapor lock. The whole fuel line would be pressured. You might have a bad fuel filter, or plugged injectors. good luck.

You should be able to hear it for a couple of seconds when you turn the key on. Have someone turn the key on while you are back by the gas tank. When they turn the key on it should make a noise for a couple of second. No noise, pump is out. If the engine light is on, then your problem is an oxygen sensor or manifold sensor. Have it tested. Take it to Auto Zone they will do it for free.

disconnect th fuel line and see fuel stream to verify. where are you with the 40 degree C thing?
