here is a list of what we have tried.

1) looked for air leeks in the intake and found non (when running you can see the air intake hose compress a small about due to the vacume in the line)
2) used a noid to verify that the injectors are getting electrical signal
3) directly tied the inline external fuel pump to the battery and tried to start the car ( when doing this you could hear the pump and the regulator bypassing the extra fuel pressure when not trying to start the car)
4) disconnected the by pass side of the pressure regulator on the fuel rail and about 2oz of fluid comes out when the key is ingaged to the run position
5) hooked up to the feed line on the fuel rail and pressure goes to 55psi when the key is ingaged then if ingaged again to about 85psi
6) examined the air flow meter and it functions open and closed smoothly.

All of the above resulted in the same results with the car running for seconds and cutting out.
Ok. I assume you have plenty of gas,(past 1/2 full to rule out the in tank pump and it's fickle often failed connection) and that your battery is FULLY charged. The vacuum leaks you assure us are not present, but there are many places they can be, so I will leave them up for further discussion.... The thread http://www.alfabb.com/bb/forums/spid...6-project.html will give you an insight on my recent finds on an 86 car, but I still suspect a relay issue, or at the worst, a major vacuum leak. good luck, and post your progression/regression. The drive relay is behind the passenger seat under the horizontal "back seat" area. It is prone to failure. It seems to be a logical or probable source of your specific issue. Good luck. Hope it is a simple cure!
