After an astounding success with resealing theEAS block on my 96MY. I did the oring job and diaphragm on a (known to work, but leaky) spare for my 01MY, didnt work, pump runs, no air leaking from exhaust port, all solinoids click when using the pigtails, but not enough pressure in the system to function, there is some pressure there. took it apart to see if i had made any blatent errors like putting theNRV's in wrong, dislodged an oring etc, nope all looks good no apparent blocked ports etc. put it back on still not functioning, took it off and put it on my 96MY nope doesnt work on it either so the fault is definately in the block somewhere. I leak checked the airlines all Ok. and the 01MY now works fine again with its original untouched block refitted.
Any ideas anyone?
