Thanks for your help so far. Had to move vehicle of the street today and tried to start engine again and engine run on "fumes" for a fraction of a second only.
Here is what I have checked:
1. Ignition is fine - the plug get a good spark
2. no power supply at pump while trying to start engine
3. plug the pump relay - no corrosion
have no spare relay to try out. Any other way to check power supply to pump?
tks, Marcel

Thanks for your help. Today I took the time to check everything including the fuel pump relais. I found a broken solder connection and fixed it. That was all it took. However, a new relais is on the way.... just in case.
