Chevy express 3500 turns over but will not start. My mechanic came to my house to diagnose the problem.The computer readings are all normal.There is a spark and the fuel is reaching ejectors, Mechanic called to say he consulted with the chevy dealer and can find no reason why the van does not start.Mechanic took everything apart and found fuel in the spark plug lines which verifys that the fuel is there(also before the van was towed,Mechanic used ether and got flame in engine.The van has been out of commission for 4 days.Would appreciate any input. thanks !

    What is the fuel pressure? Perhaps the pressure is to low for the engine to fire. Fuel pressure should be 60-66 psi with the fuel pump running and the engine off.

    Remember this, Suck Sueeze Bang and Blow. Intake, compression, Ignition and exhaust. One of those might be missing. Sounds like a possible timing problem, find a new mechanic that understands how that works
