I have a 2005 Mustang 4.0 V6. last week we were cruising along at 40 mph and the car just stalled without warning. I let it coast for a mile or so , when we came to a stop I tried to fire up again and it started but only ran for 3-5 seconds and it stumbled and stalled. I’ve tried fire it up several times since and it does the same thing. I can hear the fuel pump engage each time I turn the key.
I’ve tried several things:
Checked the relay
Check all the wiring and connections
Installed new MAF sensor
Installed new fuel rail pressure sensor
Installed new fuel pump driver module
Cleaned throttle body
I guess the next thing would be a new fuel pump???
Does anyone have any other ideas?
