SOLVED 100Q hot and cold hard starting

[Denis]

Car: 100Q 1989
engine: 2.3 na CSI-3


The car was very lazzy.
Hard to start hot or cold.
But cold i needed to start 6 time before the engine can idling.

One day the car was impossible to start. I was stuck 350km away so i putted
the belt 1 tooth back to get home.
I checked the timing and found it jump more than 1 tooth :-).The timing belt
jumped 3 teeth. I changed it.
I changed the belt.

System pressure was 65 instead of 90 psi.
I investigate and found its the FPR; i tested it with air 0 to 90 psi and
opened at 65 psi.

Force5 sold me one, i installed it in the same day and yesssss it works
good.

The engine is still shacking a little but it start at the first try and stay
idling.
