I bought another metering head yesterday, but it didn't look in as good a condition as mine and the guy set me to thinking, so I did some testing again, this time with a good possibility of measuring the fuel pressure.

When I put the car on contact the fuel pressure jump to 5 bar, then drops to 2.5 bar.
When the engine is turned over, it won't do anything till you push down the air flow sensor a little.
So when it finally runs, you have to keep above the 1500-2000 rpm's as it will stall if you get under that. A little push on the throttle will keep it alive.
After it stalls the pressure immediately drops to 2.5 bar again, but stays there, it won't drop more, nog even after an hour...
While the engine ran, the pressure was 5 bar, so 0,65 bar too low.



Who has some info now about why it won't run properly????
