2056 running L jet

Drive the car for about 30 min parked it for about 15 then started back.

It started to cut out and then just died. It will start and run for a few seconds but then dies. There is fuel and spark. Any ideas? Don't see any pinched lines any where.

Ambient temp is 77 degrees

Just tried to start it and it is still doing the same thing.

put a meter on the pump contacts and no voltage when I move the flapper in the airbox (key on).

There is voltage when the engine is cranking but as soon as it starts and I let off the starter no voltage.

Does this point to the relay?
Refresh my memory is the pump relay on the relay board in the engine compartment?


Or should I check something else?

I think you are on the right track. If you manually deflected the AFM flap, and no fuel pump action with the key on, could be one of three things. Start by testing the continuity of pins 36 and 39 at the AFMs connector. You should see 0 ohms with the flap deflected and infinite ohms when the AFMs flap is at rest. Start with this test, and report back.
