Thanks folks.
I just noticed something else as I turn on the ignition even before I try
to start the van - All four injectors are firing non-stop and that is why
the gas is pouring out of the exhaust.!!!
When I checked the injectors' spray pattern - ALL Four(4) injectors are
spewing gas non-stop into the cylinders - that is why it cannot start - THE
MOTOR IS BADLY FLOODED!!!
Could this then be a bad ECU also causing the pump to run continuously
instead of just pressurizing the system for a short time?
