'88 SL560 Ran last week, wont start now..
 

We started the car and took it for a ride last week... Today it wont start. It has a half tank of gas, is in park, and fuses are all good. Got ride of the obvious overlooks. Hit it with starter fluid and it jumped to life (so we have fire) but dies soon after. Pulled one of the fuel lines from the fuel distributor and put the key into the on position that primes the fuel pumps, got no fuel to the open hole where the line was removed. Removed the fuel "in" line same thing, no pressure. Checked pumps and relay, all functioning. Rechecked fuel "in" line to the fuel distributor and now I got pressure, but still nothing to the lines off the top.

Any ideas guys, we don't drive this car much but do keep it maintained, how did it go from running fine last week to squat? I am vehicle savy so if you have any thoughts, throw them at me, I have been restoring cars for years but I am stumped on this one
