Airmatic Question - Am I missing something?
Replaced compressor, confirmed no air leaks, replaced relay with Hella, and all fuses. Compressor will not turn on after battery reconnected. Suspension now dropped to lowest.
Am I forgetting a step? I was under the impression I wouldn't need STAR...
Thanks all.

The engine needs to run for compressor to come on.
I never experienced any limp mode on airmatic, even I had some trouble with it.
I mean I have rear air only, but per my observation, with pressure gauge added to the system, on each engine start the system self-check.
So if you have no power to the compressor, you have electric issue.

Thanks for the responses. The dealer told me today that I didn't need STAR, etc.
Plutoe is telling me clearly I haven't isolated the problem and need diagnostic.
I don't understand what it could be other than another faulty relay?
I've started the car and let it run for a bit, new compressor will not click on. "Too low messages" after about 10-15 secs.

Plutoe is "keyboard mechanic" when he is great is copying pages and seeking info, he has no real life experience.
Even when you scan the car, the error will be
"compressor running time exceeded"
or "compressor electric circuit is not responding"
You should get power to the compressor in the second when engine starts.
Get one of those $2.99 light tester and get on fuse box.
Or you can listen to Plutoe and spend $150 to learn that you have no power to compressor.

SOLVED
Ok - found the issue - it was the passenger foot well 40A fuse (#74). It was blown. Luckily, I found another post that had this info as a check.
So ten more minutes and $4 saved me a ton of time (and money.)
I do find it interesting that neither Indy OR dealer told me to check this fuse. I wonder how many pumps, shocks, relays get replaced when its just a simple fix.
Thanks all, for your contributions. I appreciate the differing opinions and ideas - it is what makes this place truly valuable!

I recently had an intermittent bad connection in the plug for the compressor. Checked the relay, and thought I had a dead compressor, until wiggling the connector could bring it back on. Cleaned it a bit, added dielectric grease and tried to improve the pin tension a little, seems to have cured it.
Good luck,
Rune
