Let us know what you've tried so far.
Starting from scratch I'd say it sounds like you're getting spark if it will fire on the cold start injector. You should check to see if you're getting a pulse signal at the main injectors. Get ahold of a noid light ( you can "borrow" them from auto parts strore that has the program), plug it into an injector connector and see if it flashes when you crank the engine.

Giuliot Turtturro sent me this file a few weeks ago. Is this the file you are looking for?

tried it again today....was able to keep engine running above 3k by pumping gas pedal , but the engine soumds like its laboring and the boost gage increases... I tried un pluging air flow sensor , but it wouldn't start at all ...Injectors must be working , sounds like the gas is being shut off,, GGallo

Thatt sounds contradictory. You say the injectors must be working, but that it sounds like the gas is being shut off. The gas is supplied by the injectors, if they're working the only way gas could be shut off is if your fuel pump stopped running. If your car will run by pumping the pedal then the fuel pump is running. Do you know that when you pump the gas you're not giving it more gas, you're opening a flap that allows more air to enter, which in turn opens the flap a corresponding amount in your air flow meter, which moves the contacts farther around on the resistance track. This is read by the ECU as a demand for more gas and it signals the injectors to stay open longer. So it seems like you're not getting a good fuel/air mixture ratio. Take the boot off your AFM and see if the flap moves freely throughout it's whole range of motion..

That is one of Brad Artique's fine manuals. That particular one is an outmoded one available from a few different sites (Mira and Xweb). He would prefer you grab the current one from his site:

Hope that helps.

I'd bet the injectors are gummed up with varnish

After checking everthing electrical , which was good ..I had 3 other people (mechanics) check it and they didn't find the problem !!!!!!! At last I removed the air flow.but kept it pluged in ,had person start the car and I moved the the flapper on the air box !!!!!! I was able to keep it running !!!!!!!!
Back some time ago when starting the car it Backfired and broke a small piece from the tube that goes from air flow down to inlet of the tubro (very tight and hard to see ) ..... After repairing flang at turbo end , it runs great..
I hate to ,but I'm going to sell it now ,its getting to hard to get in her !!!!!!I have enjoyed it for 28 yrs
