sonofsam 5 Posted March 11, 2006 Hey Chaps. Wired in the last of my cables this morning,stuck a charged battery on and cranked it. I can hear the fuel pump working and starter motor turns over but it wont fire up. Any ideas on what's going on and what i can check Cheers Sam 95% happy man.

smckeown 1 Posted March 11, 2006 when i've read posts on here before, the advice seems to be that as long as there is spark, fuel and compression it should start. Share this post Link to post Share on other sites

Ant 2 Posted March 11, 2006 Nice one Sam.. Better than it going bang anyway Hopefully ull get it running 2 moz Share this post Link to post Share on other sites
Alex G 0 Posted March 11, 2006 sounds like keypad/immobiliser problems? have you wired it all up Share this post Link to post Share on other sites
sonofsam 5 Posted March 11, 2006 sounds like keypad/immobiliser problems? have you wired it all up Got no keypad and the ecu is unlocked,think i have connected only one switch live wire to 2a. Nice one Sam.. Better than it going bang anyway Hopefully ull get it running 2 moz Cheers Ant,yeh i was brick'n it a bit about turning the key,atleast the cobra immob didnt seem to cause to much bother.

Alex G 0 Posted March 11, 2006 i think i remember having a permanent live too! can you hear the ECU when you switch the ignition on (Just put your ear on it) then when you crank you may not be getting power to the ecu! Share this post Link to post Share on other sites
sonofsam 5 Posted March 11, 2006 i think i remember having a permanent live too!can you hear the ECU when you switch the ignition on (Just put your ear on it) then when you crank you may not be getting power to the ecu! yeh i got those hooked up,two big brown wires attached to the slam panel fuse box via a 205 plastic spade connector. Unless i have mixed these up,cause there is 4 big brown wires.may of hooked up the wrong two must admit i did'nt listen for the ecu hum. Share this post Link to post Share on other sites
Alex G 0 Posted March 11, 2006 as i recal, one of the main power lines that i ended attaching to the slam panel actually followed the rest of the harness into the car on the 406. Just check the ecu is actually on when the ignition is on and when cranking, and then if it still wont start ou may have to feed another switched live to the ecu,where the keypad used to connect (However im not sure about that as i used the keypad) Share this post Link to post Share on other sites
jacobs53 0 Posted March 12, 2006 pin 27 needs a 12 volt feed either from the keypad or a switched live lee Share this post Link to post Share on other sites
sonofsam 5 Posted March 12, 2006 pin 27 needs a 12 volt feed either from the keypad or a switched live lee That's the one !!!!! Just connected it to the switch live.....And gues what ITS Alive Were's that Champagne Share this post Link to post Share on other sites
jacobs53 0 Posted March 12, 2006 alwasy the one that catches people out. And by the way if you have a keypad car and you don't know the code.... just connect pin 27 to 12v live works every time lee Share this post Link to post Share on other sites
Ant 2 Posted March 12, 2006 Nice one sam No doubt ill be harrassing you in the near future for wiring advice Glad u got it started Share this post Link to post Share on other sites

Hilgie 16 2 Cars Posted March 15, 2006 Unfortunately there's no such thing on the 2.0T engine as the wirenumbers are almost never there. I always use a schematic (which is the same for all 2.0T enginelooms) and go from that. Then it's just measuring. In fact and that would be the easiest for you I guess is to leave the sensors for the dash and startermotor on their old 8V loom and wire in only the live, switched live, and fuelpump from the 2.0T loom. http://www.student.kun.nl/p.oonincx/downloads/xu10j2te-1.gif As you can see in the schematic item 1304 (the large brown multirelay) is the most important thing. Constant live should be on pins: 15,14,11 and 8 Switched live should be on pin: 3 (which connects directly to wire 2 on the 205) and on pin 27 of the ECU Fuelpump is fed from pin: 9 (which connects directly to wire 76 on the 205) This way the engine should at least be running. Also note that above wires are all on the round (or square) multiplug on the engine loom. So just a case of measuring from the relaysconnector to the multiplug to see which wires are which. Have fun!
