I have a 2000 taurus, it starts very hard takes many tries. When it finally does get going it billows white exhaust. Once it is warmed up it starts fine. Even tripped inertia switch till it stalled and starts right back up. Got a code 1233 and a code on the egr valve.I've got power to the egr valve when the ignition is switched on.
Fuel Pump Driver Module (FPDM)
DTC P1233 or P1234 present in Key On Engine Off Self-Test
Key on, engine off.
Measure voltage between the FPDM PWR pin (VPWR for Continental) and ground pin at the FPDM harness connector.
Is voltage greater than 10.5 volts?
If Yes REPLACE FPDM
