1985 911 crank no start issue after sitting

Hello All,
I am hoping to get some direction from the experts on a starting issue I'm having. I've been working on my bug for the past 9 months so the 911 got put in storage and hasn't been started since. It did run great when I put it in.

I went over the other day to swap cars out and bring the 911 back home but it wouldn't start. It had a trickle charger on it and cranks over no problem but no start and no fuel smell at the exhaust either. I noticed I didn't hear the fuel pump so I replaced the DME relay with my spare which is new. Nothing changed.

I then came home did a little research and went back to check the fuel pump and all the connections. If I jump the fuel pump fuse to another fuse I do hear the pump run. I also pulled the battery to see if that would reset anything which didn't help.

I'm going to make that 3 prong jumper for the DME harness to eliminate the possibility of a bad spare DME relay. Any other ideas of what I should check on my next visit? I've never had problems with electronics going bad from just sitting but the car is getting old so I guess it's possible.

Oh, I also feel the idle valve vibrate when the ignition is on if that matters.

Regards,
Jason
