After a couple of weeks of trying to start it I went by a Motorworks here in Winston where they work on Porsche's. I talked to the guy that knows CIS named Bill. He told me how to verify timing not 180 out and if I was worried about compression to put some oil in the plug holes and try to start. Well I did that and IT STARTED AND RAN FOR ABOUT 20 SECONDS. It sounded really smooth but tons of smoke. I tried to restart and got nothing so I pulled the plugs and they were covered with oil. I am going to clean them and try again. I don't think it's getting any fuel possibly due to settings and low initial fuel pressure. No gauges do I own. If it won't start after the plug cleaning I'll check the plugs and if they are clean I'll add some more oil to the plug holes to get some compression. I am down to compression and fuel. I am going to try and keep it running this time by spritzing. Gunar

You know with this comment....."No gauges do I own. " You appear to ask for advice but refuse to take it ! With no pressure readings you have no way to know what the CIS is doing either buy a couple gauges or take it to a shop and pay them to check it out. Other option is buy a rebuilt fuel dist. , rebuilt control pressure reg and 8 new injectors but even then you should have the gauges to confirm pressure.

Yeah- I'm afraid this is a possibility. I am holding on to the comment someone made that if an engine has sat for years it could show low compression and still be alright once it was run some. I don't know if this is true.

You'll also find it handy to get a copy of How to Tune and Modify Bosch Fuel Injection
Roger also sells the gauge set - not sure on his price tho'.
As for the possible compression issue - its unlikely that compression will be bad in all cylinders; I'd expect the engine to start and run if it were just one or possibly two cylinders with a sealing issue. Before you start chasing ghosts, verify that the CIS is working correctly (i.e. use a gauge set). You need to start eliminating possible causes of no-start before making assumptions and spending money unnecessarily.

I can get it started if I add oil to the cylinders through the plug holes and clean the plugs off. It starts on the first hit and I can run it as long as I want as long as I don't let the idle fall too low then it dies fast and won't restart unless I pull the plugs and add more oil in the cylinders. This is quite inconvenient. I plan on starting it again and running it for about 30 minutes or till 9 gallons of fuel is gone and see if that helps seal the rings. If this doesn't work it looks like I need to just change the rings. Mixed emotions here. Gunar
