problems starting the project 911sc
 

As a few of you may know I bought a 1980 911sc back in February. I opted to go with a project car without engine or transmission a horrible interior missing seats etc. I’ve been buying numerous odds and sods from many pelicans and the pelican site. I bought a bunch of manuals plus both of Wayne’s books and went to town on trying to piece this car back together. So after finding an engine, rebuilding in with the help of Wayne’s book, my dad and numerous different shops around Houston I’ve finally got the engine and transmission back in the car.
So I prepped the newly rebuilt engine for the big moment. Got oil in it, I siphoned all the rotten gas out of the tank replaced with 5 gallon of premium, built up oil pressure As per Wayne book, checked compression on all cylinders, triple checked timing (ensuring rotor was pointing to cylinder one at TDC during the compression stroke) I did have a few plug wires that I realized were incorrect changed them following the proper counterclockwise method (no thanks to Bentley) but I still can’t get it to turn over. I’ve got good spark but I’m still a little concerned about fuel?
I didn’t drain the fuel line from the engine to the tank so that rotten gas would still be in the line? as well what about the air in the fuel line does it need to be bleed out? Any help would be greatly appreciated. Thanks again – I’ve thrown in a few pictures of before and after of what I have so far but I’ve still got a fair amount of work left.

Great work!

First off thank you for changing those fenders!! :eek: I don't know how many of those I can take.

Not speaking from any Porsche experience, but I would look up the fuel injection section on the bentley manual. It has a diagnosis for testing the fuel pressures and output volume. I would run the output volume test until I got clear, friendly smelling fuel out of the fuel supply line. This should be easy to do with an electric pump, probably just need to turn the key to the position just before start. Hope this helps.

Looks like your previous owner really ran that one hard. Almost as beat down mechanically as mine. Did you have a completely bald pass. side rear tire and tread on all the rest like I did.

Good luck, and take your time I know it is very easy to accidentally look over things when in a rush @ this point in the build up.

Pull and injector from the runner, turn on the key and lift the air meter plate. does fuel spray? If so, crank the engine while lifting the plate. You may need a helper. This should allow you to start the motor and ID possible problems with the cold start.

Thanks for help guys hope we can meet up for a run here in Texas when I get this thing on the road. I got the car started here about an hour ago, I checked my timing again for the third time and realized it was still off, it started up no problem this time round.

I had a good laugh at the fender comment I couldn't hardly give those things away we I went to sell them.

Por-tex:

Wow! Nice job on the engine. I think Ferry would be proud of this work.

Hey! It looks like a 930.

Cool, you did good.

Glad it started. The engine looks great.

+1 on the comments about those sick (bad sick) fenders. Are they fiberglass? If so, burn them and invite friends over to watch and have a few beers while they disappear.
