so parked the car... all worked fine...
stopped at autozone to get a replacement headlight as one was out
came back .. replaced the headlight go to startthe car.. NOTHING
power to everything ..lights... windows..BUT
no pump... no ignition .. no starter..
hook up scanner...
NOTHING .. no communication to scanner at port .. no crank ..
jumped starter relay to check starter.. turns over.. but no fuel pump
changed EVERY fuse and relay... all check out and work as should.. EXCEPT no ecu power.. no pump .. no crank
whats up ?
Model: 2004 ford explorer sport trac
Year: 2004
What have you tried so far?: changing all fuses and relays.. jumping out starter to make sure it cranked
the relays under the hood do click like the are getting a signal when you turn key fwd to run/start
with scaner connected there is no signal from ecu and scanner "will not connect"
when I jumped out the starter relay the truck turned over
The fuel pump does not come on and the data port will not communicate with 3 different scanners I tried
I'm guessing the computer is controlling the pump and with out the computer nothing happens
If all fuses are good what would stop the ecu or data port from getting power
The cig laughter works also
