SimonHawtin Posted September 28, 2014 Share Posted September 28, 2014 I have swapped my 1.8 si engine out for a 1.8 130bhp, and i have the correct ecu for the new engine and it has had the pax code removed(checked at ford) so it doesnt need to have a key matched to the ecu, but it will not run ..lights come on the dash but the engine will not turn over and the i cant here the fuel pump prime.but the engine will run on the old ecu...very lumpy and it doesnt like it very much. Any ideas as its driving me crazy. cheers Simon. Link to comment Share on other sites More sharing options...
scottybo Posted September 29, 2014 Share Posted September 29, 2014 Should run fine on the 115 ecu. Are u using a 130 maf as well? That may be your problem Link to comment Share on other sites More sharing options...

sidrick Posted September 29, 2014 Share Posted September 29, 2014 Should run fine on the 115 ecu. Are u using a 130 maf as well? That may be your problem No it won't. A MAF won't stop a fuel pump from running to my knowledge. What are the two ECU codes? Link to comment Share on other sites More sharing options...
JC Posted September 29, 2014 Share Posted September 29, 2014 Have you had the "new" ecu checked over? Link to comment Share on other sites More sharing options...
SimonHawtin Posted September 29, 2014 Author Share Posted September 29, 2014 I have had the ecu checked over by ford. The engine is a motorsport 130 Bhp and the ecu was fitted in car and running when I bought it, but engine hates my old ecu and runs very lumpy. It look like throttle bodies now as I cant get to run correctly. Link to comment Share on other sites More sharing options...
scottybo Posted October 1, 2014 Share Posted October 1, 2014 No it won't. A MAF won't stop a fuel pump from running to my knowledge. What are the two ECU codes?the incorrect maf will make it run lumpy tho. I know it shld run on because im using a 115 ecu in mine atm Link to comment Share on other sites More sharing options...
Craig855S Posted October 3, 2014 Share Posted October 3, 2014 yes what year is the car? And what are the 2 ECU names (4 letter word) If you have a PATS car and you're trying to fit a NON PATS ECU to it you need to follow the "how to wire in a 2.0 ECU" guide in the how to section as non PATS ECUs from earlier zetecs are all wired differently and wont start if not altered.

Stu Posted October 8, 2014 Share Posted October 8, 2014 The guy at Ford lied to you. You can't 'remove a PATS code'. 1 Link to comment Share on other sites More sharing options...
Stu Posted October 15, 2014 Share Posted October 15, 2014 You can reset an ECU to learn new keys, though. Link to comment Share on other sites More sharing options...
