a year ago I got the po410 code. Air pumps not working, so I replaced it & it lasted 1000 miles. That was an Ebay China pump so this time I bought a Bosch. Lasted one day & fried the pump & blown 40amp fuse. Tested the soliniods with a vacuum pump, replaced the vacuum lines. Checked my head passages. All seems ok?

also for some reason one of the vacuum lines comes from under the intake manifold. I broke that nipple trying to get the old hose off. So I blocked the hole & took vacuum from the top with a tee. Hope that doesn’t matter?
