swapped the ecu over and the black plastic transponder thing and car still wont start pats imobiliser still flashing like mad anything ive missed

 

Drop Tank Mike a PM, he does loads of Puma conversions onto mk4 fiestas etc as part of his day job (he does engine conversions for a living) and knows loads about the immoblisers etc.

He's a really approachable guy so Im sure he wont mind chatting to you about it

 

theres a chp inside the key did you change that?

 

no because i got ecu key to match the ecu, barrel and key transponder sender that fits over the barrel as a package, i thought swap it all over and it should start but guess not

 

When you say it wont start, have you looked into why?

Ie does it turn over?
Is there a spark?
Was it running on the old ecu, if so why did you change it?
Does the rev counter move when you turn it over?

 

have you got the correct ecu?

could be digital and analogue

 

yes car started fine misses lost her only key, so bought a ecu of ebay with new key transponder and barrel swapped it all over, and car wont turn over light just go dim when turn key,starter dosent move so i no its an immob problem both ecy say muff on them

 

thats weird make sure all your connections are in correct

 

it should work with wot you have done . the only thing it could be is one of the parts is not part of the set

 

well went over everything took it off fitted it back again and guess what starts 1st time lmao well thanks for your helpfull posts best forum for help

 

Hello mate, it defantly sounds like they've aol you a dud transponder key and ecu. I think they've miss matched the keys. Everything you have done is spot on. The transponder is built into to the buttons side of the key so you can change the key part retaining the transponder code if that makes scence. The only thing I would sujest is to put you original reciver back over the barrell as there are 2 differnt ones and I don't know if they are interchangalbe. You don't need to change this part when fitting a new key or ecu anyway. I have a puma powered fiesta here if you wanted to send me the key and ecu to test it but it's a bit of a long way round. If you have used the new barrell with the new key and new ecu it's should start.

Also make sure you have the correct ecu. There are 4 types

Muff
Tape
Tape- puma racing
Dive

make sure you put the correct ecu back.

If you want to call me for some info or you can't read my bad spelling feel free to call me on 07985266042. Cheers

 

DUDE - 1st Generation Puma
MUFF - Up to summer '99
TAPE - Std fit on '99 Summer - 2000 Spring Puma
DIVE - Std fit on Spring 2000 onwards Puma

Assuming it's the 1.7. The 1.4 and 1.6 Puma used other types. (TEAT as well as others I think)
