no it doesnt (didnt) collapse overnight and would sit easily for a week..no leak down. I see these air pumps (one model a rebuild supplier says, wears out quickly according to them and the system was very serviceable for a year..) I see various leak points other than the shocks themselves which are possible, the manifold and hoses..

You ask, tjts1, 'when I inflate the airbags...' I cannot inflate the airbags at all. The pump does not come on at all, and thats my primary issue at this point.

I may get a scan tool which could interact with the suspension, Id like to have it for working on the brake system as well. Recommendations would be appreciated for something short of a professional level scan system..around $500 or less would be very worthwhile.

Thanks so much..
