Good so go fit a bosch.To confirm take out the fuse and put your meter set to 10A between the positive bolt adjacent to the fusebox and each of the fuse terminals ...if the pump is OK you should get a reading on one of them . Ignition OFF.
You may get advice on how to access the original pump but like I said I can neither see it or feel it so no chance to get it out. (Could try me new Borascope !! )
When fitted you must check the fan that draws air over the sensor in the dash and clean fluff off the sensor.

ha ha. I listened up, and read your lips, way back on your post #4 and then tested the motor for continuity.

As mentioned previously, it has none so all signs point (at least) to a bad motor.

thank you for the help.
