Hi everybody! I am a new member here and have been reading and learning a lot on this forum. Any ways I happened into a 1977 Porsche 924 for 100$ so I figured why not. I am pretty mechanically and I'm thinking it will be a fun project. Don't really care about putting money into even if its not worth it, just want something to work on. So to the car It hasn't run in 2 years and has been set up on blocks. I drained/cleaned the gas tank, drained and replaced the coolant, added brake fluid, changed oil and oil filter put a battery in her. Replaced the starter (original issue for being parked). Tried turning it over and after a long time it would sputter blow smoke out of the muffler and nothing. It does that very rarely. I'm getting spark. Set the timing correctly (I think). and I pulled the fuel line at the distributor and it seemed to have a nice flow when the car was cranked and then I took the fuel line off on the out put side to the injectors and it seemed fine (although I don't know what kind of pressure to look for). I just pulled the injectors tonight and it seemed when it first cranked one would spray then nothing but it was a different one every time it was cranked. So I'm at a loss I believe I have Air fuel and spark but no running!

Any help would be appreciated! Thanks!!

Try the procedure I described here..
http://924board.org/viewtopic.php?t=41269&highlight=

It involves jumping the fuel pump to test the injectors in bottles instead of cranking, manually pushing the air flow meter plate by hand to simulate airflow..

The injectors should all always spray a the same time, the same amount, and stop at the same time, never just one at a time..

This is CIS, Constant Injection System, the injectors spray Constantly vs pulsed as in electronic fuel injection..

Thank you I will try it when I get home later this week. If that works fine what else should i try? If they are broken is it easy to clean or should I look into buying new ones?
