I have a problem with my car when it is warm and I'm going to start it. The problem is that it does not start ... :) Its a 1992 with one single injector.
(note that this text is made partly with Google Translate so the grammar is not the best):)

If the engine is cold so it starts without problems.
But if the engine has been run and reached the working temperature and I shut it off and restarting it again, so it would not start again.
It is running for a second maximum, then it dies just like that. And would. Not a life of it.

When the engine is like this weird, I have to knock on the injector a bit, so it has started again. I switched to another second-hand injector from a 1400cc engine, and the car started and I thought the problem was gone. But it resurfaced when I would start the car when it was hot.

I have also tested if the injector sprayed/injected gasoline when the engine didnt startet, but it did. So gasoline problems it not the problem..

Sometimes, when I got the engine running after I been driving on the starter, have been pumping on the gaspedal to get it to stop going bad. While I pumped the gaspedal as I experienced it, as it periodically broke the ignition. At least it sound like that. And somewere at 3000 rpm it stopped sounds bad.

Does it feel familiar? :confused::(
 
Any engine need only air, fuel and spark to work correctly.

Start measuring the fuel injection pressure on the TBI input, on both warm or cold situation.
Must be around 1 bar.

How old is the fuel filter?

ps. TBI means Throttle Body Injection.
