Restart of Stored 450SL

Any tips on restarting a stored 450SL (1974)? I lubed the cyls from the top and soaked it for about 5 days.... then changed the oil and cranked with no plugs for 5 - 8 seconds until fuel pressure came up, then would let starter cool and do it again.....

Great spark and new plugs and 37PSI of oil pressure on starter alone, but it won't fire with fuel or starter fluid poured into intake flap.... The fuel system is dry right now as I've blown it out with an air compressor and am working on getting the fuel pump spinning (or will install a new one).

The car has 120000 miles and was running great when it hit the tree about 8 or so years ago. No clinks or clanks and I've got the fan off but have left the other accessory drive belts in place so far.

Car was simply parked outside, hood down and air cleaner etc intact. No rust or seizing in cylinders and it has good "suck" at the air intake but I have not done a compression check yet.

Anybody have any advice on getting this fallen angel to light up? Is the lack of fuel enough to prevent even a "think I can" vroom on poured-in fuel or starter fluid?

Thanks!

An engine needs three things to run. Compression, a burnable air/fuel mixture, and a spark at the right time. If it won't fire, one of those is missing. How are you checking the spark? At the coil, or at the spark plugs?

my 76 450sl was a basket case when I bought it; wouldn't start, coughed, wheezed, etc. One mechanic said it was hopeless, major engine work, etc.
a can of starter fluid and new gas did it for me. got it running and with each mile that new gas ran through the system, the better it all ran.
that may not be your situation, but worth a try.

450 SL probs

I don't know for sure BUT it sounds like fuel.
I just wholesaled my SL for body reasons and have: Brand new fuel pump (Bosch in box), the complete throttle body assembly w/ a NEW fuel distributer, a brand new exhaust system for it, and Full (engine & body) factory shop manuals. If you 're interested they are all for sale!............gmoross@nycap.rr.com
