280SE fuel injection pump kaput

[jbirdga]

After letting my '69 280SE cab lay up for over a year (I know - bad, bad) it will not run. There is just a marginal amount of fuel output from #4 and #5 spigots.  I have confirmed adequate fuel pressure and we got it to chug a bit by hotwiring the cold start solenoid.  The pisser is that I had the pump rebuilt ($900!!) just a couple of years ago.  can anyone offer advice on what to do now or does anyone know of a pump builder who specializes in these and lives on the Northeast - I'm hoping to find the guy who did the original overhaul to see if he can help me out now - I lost his name and receipt (I know - bad, bad).  Thanks!

Had a similar problem when trying to start one of my pagodas after over a year. Here's the thread: http://sl113.org/forums/index.php?topic=7100.msg44768#msg44768

First, make sure the petrol supply to the injection pump is good (both quality and quantity).

Second, review the 'Injection pump tour' by Joe Alexander (see technical manual or search forum archives).

Next, you need to make sure the rack in the injection pump still moved freely. Mine was stuck from sitting that long, and I freed it whilst the pump was installed.
There is a little threaded cover on the face of the pump facing toward the front of the car. This is an access hole which allows a long 4mm bolt to be screwed into the front of the 'rack'. Do this and then try to move the bolt (and rack) in-and-out. It should move freely.

If it does, then the next step would be to make sure all the lines and injectors are clear.

Let us know how you come along.
