It could be a leak in the vacuum lines. Mine was leaking in the T-piece in front of the brake booster( upper right corner on the picture).

Kizmax,

Forum etiquette rules that you only use uppercase when you are angry.

Otherwise it is polite to use lowercase.

Regards,

Hi the best way of testing the diaphragm on the inj pump is to apply a vacuums whilst the engine is running, if the diaphragm is ok it will stop the engine. If you haven’t the tool then attach a vac pipe direct to the cell and suck (hard) you should be able to stop or at least slow the engine down, use your tongue to block the end of the pipe (is it holding the vacuum?) it should, if not replace it. There is a lot of other places you could be loosing pressure.
regards Tery
