GP may not be working. GP's are on a timer based on coolant temperature, so not certain how you leave them on for 20 seconds when operator has no control over the on-time.

Suggest you thoroughly check the GP wiring circuit for the root cause.

Time should vary with temp, but sounds like you're following the general procedure.

I'd verify full power is reaching the glow plugs and that the GP's are functioning correctly by measuring their resistance.
