Loss of pressure?

Post by Flying Dutchman » Wed Oct 29, 2014 7:26 pm

I wonder if the fact that I have to run my car on the starter several seconds before it ignites, can be caused by a pressure-loss in the fuel line?

I recently fixed a fuel leak (crack in the fuel pump fitting) and that made the car start better.
Better in the meaning that if I've parked for exampel 3hours it starts immidiately when I turn the key, but if parked over night, same issue. Before this fuel leak repair, I always had to run it those extra seconds..

Can this be casued by a worn check valve or something?

I ALWAYS turn key to ign position, wait until the fuel pump noise stops then turn key to starter point.

This ensures that fuel line is pressurised and injectors get a decent shot instead of priming the system AND turning engine over, if not takes a wee bit longer to fire up.

this is same with TWO pumps (in this car) and two different cars, one a 1800 and one 2Litre

Good thinking. But my fuel pump doesn't start until the engine revs more than 45 rpm (1990 turbo) so in my case theres no point of waiting. I get the best starts after being parked a couple of hours. Over night starts and start after a short stop (warm engine) is the problem..
