Engine won't run for more than 10 seconds

Hi All,
I just took my 81 FI out of a 4 year storage. Emptied old fuel. Fuel pump bad, so it was replaced, along with a new filter. New fuel with Techron was added to tank. Car will start, but will only run for about 10 seconds. It sounded like fuel starvation, so I jumped the new Fuel Pump, with the same result. Also checked the air flow meter flap and it's control over the fuel pump. Spark seems ok, at least when cranking. I realize I may have dirty / clogged injectors, but I don't believe that would shut the car down after 10 seconds. HELP !!!!

Thanks

If it is working for a few seconds maybe only the coldstartinjector ist working.
Often the groundcontacts (on the top of the aircollector ?) are in bad condition.
Or the temperatursensor on the "T"...

I concur, your other injectors are not working, just the cold start injector.

Combination Relay? Very common symptom of this being bad.

That damn combination relay....I reckon its the casue of most spider FI problems, including fuel pumps.....
