    I've only ever seen plugged injectors. Even new ones, once they have had fuel run thru them and the car sits for a couple of years, petty much guarantee they'll be stuck. As others have said, tap each one with the plastic end of a screwdriver, or as I do, the rubbery end of the spark plug tool "T" bar and you should get them working again to where the car should start. Def get them cleaned if the car is returning to regular flogging!

      Go figure just had a Nor'easter drop a foot of heavy wet stuff and the next day it's 40F! My heart goes out to the folks in the mountains north of LA, with 6-8x what we got, that stuff is CRAZY!

      Finally got back under the car to finish the hose clamps on the new fuel lines to the engine. crank, crank, crank, no signs of life.

      Thread is 6 years slumber, just checked and the last registration was 2014!

      That said the last few months had done all new soft fuel lines froe the pump and filter forward. New fuel filter and fuel line damper. New injectors, checked injector cycling from ECU, good on all 4. Checked spark, good. New crank sensors, Checked both fuel pumps, good and good. I know fuel was getting to the "engine" has had slight seepage at the fuel rail until I got proper hose clamps.

      Plugs were still dry after cranking, what was left to check?!

      All that I could think of was that I crossed the fuel rail inlet and outlet when I ran the new lines from the chassis mounted hard lines. Kinda like changing V8 cap wires 1 at a time so you don't mess it up, I didn't follow that wisdom and it was confirmed when I disconnected the "outlet" line from the fuel rail and was met with a very pressurized stream of fuel.

      Swapped the lines at the rail and voila, after the lines filled again with gas, second cranking try, it coughed to life! It will be on the road this season!

      Thanks to all for the step by step walk throughs and pointers. I've got boxes of maintenance parts awaiting warmer temps and the M will get some deferred love.
