CIS fuel pressure test WSM range in ( ) Cold (2.0-2.3) actual 2.2 Warm (3.3-3.7) actual 3.4 System (5.0-5.6) actual 5.3 Rest (2.7-2.6) actual 2.8 Note: When I turn the test valve to check system pressure which closes the line off between the FD and WUR the motor stumbled and had rough running. Tried to rev motor and same effect. Not sure how it should run with closed valve when testing system pressure. Does anyone else have any experience with system pressure checking and how their motor reacts? Thanks Wayne
Have never come across any instruction to make those measurements with the engine running -- they are only specified to be done with the fuel pump running (engine not running).
Humm. Ok. I was following the write up of a 328 by Carl Ross 2004. It makes sense to test the system pressure with motor off. I presume I would have the same system pressure. Hoping not to re-test as it was in spec when running.
