Problem fiesta 1.4 2004 immo on

[m3m5]

hi mates! i have got a problem.

Original ecu it?s broke and car don't start, haven't got signal to ignition coil.

we have replaced by used part. it's siemens the same number.

i have making keys with tango in 93c86, but car don't start, it's blocked.

can you help me??

You try to diagnoze the car?From old ecu u can reed any data?If u have posibiliti to reed old ecu u can write in to the new ecu old data and car must start widawth key program,if u can recevi ani data from old ecu put the tester to see wath truble code recive.

old ecu fails said
ignition coil 1 and 2 bad ( i don't remember code Pxxxx)
possible fails coils, wiring or ecu

we have replaced coil. only have got one coil.
Old ecu moves engine but car don't start.

we have bought used ecu but problem now it's immo. Now i read and said problem in pats3. Car don't move start engine.

i have add keys with tango 4d63 and change flash like virgin original. Anything it's wrong. we think flash isn't good. Can I change flash between units? solder flash bad ecu in used ecu???

thanks

You can try to write the old flash in new ecu,but if its the same ecu u can change the flash.Make a try.
Good Luck!

If you have ford VCM you can just program the used pcm to car.

Isnt immo in 2004 fiesta. keys, instrument cluster, ecu.

Not just key ecu??

Thats why tango keys never started car.

[squirrelbandy]

problem is cluster needs initialising to ecu , you need ids to programme cluster to ecu , shake hand protocal . you cannot just make key and expect this car to start .
on security in IDS it is called module initialisation.
needs 8 digit secuirty incode as well.

[sosmecano]

just recode your new ECU wethe VCM diagnostic and car start

remove 93c86 eeprom & am29f400bb flash & put in new ecu thats all

[gadroulll]

Swap eprom 8pin from ecu and car. will start.no flash memory. Send photo ecu.
