Got problem with my 83 245 (200k miles) that need your help......I posted on turbobrick, if you've seen it there, please bear with me, just need more inputs to this problem.

The engine just died suddenly when i was driving on the freeway, towed the car back home. Put some gas on the air sensor plate (learned this from a tow truck driver), started the car, it will "run" -- i.e. there was combusion, for few seconds before the gas was gone. I can hear the frequency valve and main pump buzzing after I cranked the car and leave the key at on position. If I lift the air sensor plat, I heard kind of sqeaking noise, not sure that's gas being injected or not. So, somehow there is no few going to the system. Any hints? BTW, there is power going to the frequency valve, which make me think the frequency valve might be faulty.

Thanks for your help.
