allanallen 528 2 Cars Posted September 9, 2006 my 2.0 mi is all fitted into my car now and i'm seriously struggling with the wiring. I have the starter motor working and the fuel pump is coming on as you turn it over (via the big double relay).The idle control valve is also buzzing, and i believe i have the k-light wired in (althogh the lights never lit up on the dash). I dont however have a spark! I dont actually know if i have the ecu powering up. I'm sure i must nearly be there but does anyone know which pins on the ecu need connecting to at least let the engine run. any help is much appreciated. al Share this post Link to post Share on other sites
sonofsam 5 Posted September 9, 2006 Hi Mate I was led to beleive S16 wiring was similar to the 2.0L Turbo! I'll try and help if i can Is it running MP3.2?and does it have an inertia switch? Do you have the ECU pinouts and wiring diagrams? Sounds like your missing switch live to ECU at a guess... Share this post Link to post Share on other sites
allanallen 528 2 Cars Posted September 9, 2006 it doesn't have an inertia switch and its running the mp3.2. I've got the peugeot wiring diagrams with the ecu pinouts. al Share this post Link to post Share on other sites
sonofsam 5 Posted September 9, 2006 Well on mine pin 27 of the ECU needs a switch live usually via the keypad. If the ICV is buzzing then you got 12volts to the loom. Are all the earths connected? Share this post Link to post Share on other sites
pugrallye 0 Posted September 9, 2006 its quite easy to wire one of these up find all your wiring numbers, and they follow a pattern (as in any later pug engine) 80.. wires are aircon CC are switchable live will dig you the rest out tomorrow if you want them Share this post Link to post Share on other sites
jimbean 0 Posted September 10, 2006 hello again.. i am also in the process of putting a s16 into a 205 i have 2 looms.. the 405mi and a 306 s16 i have opted to fit the 306 but only have the wiring for the 405 so the multi plug wire positions may differ.. if you have a 306 loom if you have 306 s16 loom and the round multiplug on the engine loom cc1 pin 5 is 12 ign live from switch... make sure it does not drop to 0v while cranking 123 pin 6 is fuel pump 12v if it is a 405 mi16 3.2 late engine loom the cc1 is the 12v ign pin 2 which then could change to cc17 and cc8 the fuel pump is wire 121 pin17 the 306/405 may have a key pad imob and may need the code to run but if ecu is unlocked and the 12v main feed is to the bat and a good earth is there it will start if not it is locked and th imob will have to be wired in to unlock Share this post Link to post Share on other sites
allanallen 528 2 Cars Posted September 10, 2006 (edited) Well on mine pin 27 of the ECU needs a switch live usually via the keypad.If the ICV is buzzing then you got 12volts to the loom. Are all the earths connected? pin 27 has a switched live but the car didn't have a keypad. hello again jim, the engines from a late 405. if cc1 is the thickish blue wire that feeds the double relay, i've got it connected ive got my k light connected to wire 480 on the 405 loom which comes from pin 2 and 13 on the ECU. I have power to all the coils and injectors, theres also power at the cylinder reference sensor. at the ECU end i have a switched live at pin 3, constant live at pin 18 and an earth at pin 19. I am however missing a vehicle speed interface unit, Not sure if i need this??? cheers for the help so far guys, keep it cummin i'm sure i can get this sorted with all your help. al Edited September 10, 2006 by allanallen Share this post Link to post Share on other sites
jimbean 0 Posted September 10, 2006 the vehicle speed reference is not needed but the engine speed is needed this is the sensor in the top of the box taking reference from the flywheel. have you changed the flywheel? is it the mi16 all the wires on your last post were correct, so it must be close Share this post Link to post Share on other sites
allanallen 528 2 Cars Posted September 10, 2006 but the engine speed is needed this is the sensor in the top of the box taking reference from the flywheel. have you changed the flywheel? is it the mi16 ive had the box off to check the clutch before i fitted it, but i made sure i connected everything back up. I'm assuming its the brown plug. can this be checked in any way. cheers al Share this post Link to post Share on other sites
jimbean 0 Posted September 10, 2006 yes it is like a abs sensor get a multimeter on ac voltage connect the two probes to the conector and turn it over you should get a voltage that rises as it turns over then settles... not open circuit even better if you have a oscillerscope setting on the multimeter it will show a wave form and a dip at tdc this sensor is how the ecu knows where tdc is if it dont see the voltage and tick at tdc it wont start Share this post Link to post Share on other sites
allanallen 528 2 Cars Posted September 10, 2006 cheers jim, i'm off home to check it, could be a fair task as i'm on my own. i'll let you know how i get on. cheers again, al Share this post Link to post Share on other sites
jimbean 0 Posted September 10, 2006 use a remote wire to give the start call then you can be under the bonnet and turn it over Share this post Link to post Share on other sites
allanallen 528 2 Cars Posted September 10, 2006 I managed to test the sensor, it was reading all over the shop, so i guess its working? I really am baffled any other ideas??? anyone, cheers al Share this post Link to post Share on other sites
jimbean 0 Posted September 10, 2006 are you sure the 405 did not have a imob cos it does sound like your ecu is locked out.. all the wires are good.. all sensors working... it`s got to be locked out fella... Share this post Link to post Share on other sites
allanallen 528 2 Cars Posted September 13, 2006 12v main feed is to the bat and a good earth is there it will start sorted now!!! School boy error, i had the ignition modules earthed to the body. I moved the earths directly to the battery and hey presto, Fired up first turn!!! thanks for the help guys, specially jim, al (happy chappy) Share this post Link to post Share on other sites
