All Praise The GTI 3 Posted May 18, 2008 i got my exhaust and the last few bits on my turbo conversion today,went to start her up and no spark. i have no idea why not. did a search but no luck anyone throw me some pointers please? the fuel pump is working fine and it turns over just no spark. AFAIK the ecu is unlocked but not 100% to be honest. was out an xm and i unplugged the keypad when it was running,it stopped then i unplugged the ecu. really need it running as my insurance ran out on my otherone yesterday so i need this one up and running asap! thanks Share this post Link to post Share on other sites

All Praise The GTI 3 Posted May 18, 2008 not a clue i didnt do the loom,but i trust the loom is not at fault tho Share this post Link to post Share on other sites
All Praise The GTI 3 Posted May 18, 2008 what should i be checking? Share this post Link to post Share on other sites
sonofsam 5 Posted May 18, 2008 Well then it's possible you have a locked ECU,. Who did the loom ? Would check to see if the injectors are squirting. Share this post Link to post Share on other sites
All Praise The GTI 3 Posted May 18, 2008 rob turbo did my loom and it looks like he did a great job. top bloke to deal with. can i just unplug an injector and crank it to check they squirt? Share this post Link to post Share on other sites
sonofsam 5 Posted May 18, 2008 rob turbo did my loom and it looks like he did a great job. top bloke to deal with.can i just unplug an injector and crank it to check they squirt? Loom definately wont be at fault then! Yeah just squirt them into some jars. Share this post Link to post Share on other sites

pug_ham 242 3 Cars Posted May 18, 2008 Why are you checking injectors for no spark? I assume you've already checked its the spark thats the problem to mention it in your topic title? If there is no spark then you need to check for 12v at the coilpack plug & a working CAS sensor. Graham. Share this post Link to post Share on other sites
All Praise The GTI 3 Posted May 19, 2008 i know there is no spark as tried a plug on a lead but ive not checked if the injectors are firing just want to eliminate things altough i dont have a clue either way! sorry but whats a CAS sensor??? Share this post Link to post Share on other sites
welshpug 1,626 Posted May 19, 2008 TDC sensor/Crank Sensor, without a signal from here you won't get spark or injectors. Also check that you have power at the injectors and Coil/coilpack. Share this post Link to post Share on other sites
All Praise The GTI 3 Posted May 19, 2008 right took the cas sensor off earlier and cleaned the end as looked rusty then refitted stil no joy. i took the fuel rail off too and the injectors are not squirting. so i have no spark or squirt? does this mean my ecu is locked or have i misplaced an earth or something somewhere???

Henry Yorke 269 3 Cars Posted May 19, 2008 What ignition module did you use. The 2.0T is different from the 1.9 so you need a 2.0T one (or any other XU10 I think) Share this post Link to post Share on other sites
All Praise The GTI 3 Posted May 20, 2008 left the original module that was on the loom. the engine ran when removed. also ive noticed the fuel pump stays on, it doesnt prime then go off like it would normally??? Share this post Link to post Share on other sites
All Praise The GTI 3 Posted May 21, 2008 right an unlocked ecu off miles showed up today,thaks for that. took afternoon of work to finish off the intercooler piping and to get it running with the ecu... or so i hoped. stil wont start the injectors are not firing and i guess there isstil no spark(could not check as was on my own) really dont know what to do now, i NEED it running ASAP as i have nothing to drive! can anyone please help???

Alastairh 47 Posted May 21, 2008 (edited) Contact Rob Turbo, and ask him the pins feeds that he converted for ignition and constant live. Trace these with a multimeter, and also as Graham said, check your getting +12 volts at the coil. Let us know your findings.

sonofsam 5 Posted May 21, 2008 Does the injection double relay click whilst you are firing her up? The relay looks like this: http://s23.photobucket.com/albums/b393/djs...C01496opt23.jpg http://s23.photobucket.com/albums/b393/djs...DVC01527opt.jpg But maybe Brown in colour.

All Praise The GTI 3 Posted May 21, 2008 not sure if it clicks but ill check tommorrow. should it click then? i tried a different relay yesterday but it stil didnt start. are all the fuel relays the same as my other spare one was of a gti-6 or a 306 xsi or something that wouldnt stop it sparking tho? the plug for my CAS sensor looks a little dodgy but i dont think the wires are broken. cant believe its being such a PITA!

gti-si 0 Posted May 22, 2008 (edited) Sounds like the same problem i've got on my 6! The double relay should click when it recieves 12v yes...As the pump is running I would think the relay is working though, as without the relay switching, the pump wouldn't recieve a feed. Im not sure but the gti-6 and 8v turbo relays are slightly different, whether the pins are the same or not im unsure... IF the relay is knackered, you won't get fuel or spark. It's a case of, like i need to find out, if the relay sends a feed to the pump can it still be knakcered? As it also controls spark and fuel on cranking... Strange aswell, as my pump runs continuously, it doesnt prime then stop...weirdly got exactly the same symptoms Im gonna put money on the CAS/CPS whichever its called sensor...I'm hoping thats whats kanckered on mine Edited May 22, 2008 by gti-si Share this post Link to post Share on other sites
All Praise The GTI 3 Posted May 22, 2008 can i take another CAS of some other pug to try? are they all the same? the 6 fuel realy looks the same and fitts ok could the ignition module be at fault or my coilpack? the engine ran when removed but i guess something electrical could of died while it was in my garage?

welshpug 1,626 Posted May 22, 2008 any Pug or Citroen Crank sensor will do, the only way they vary is the length of the lead, If the GTi6 relay plugs in it will work (there are 2 types, both of which function the same and have the same pin arrangement, just have different plugs and tabs) do you definitely have 12v at the coilpack and injectors?

dan druff 0 Posted May 23, 2008 hi, you need to look at it one step at a time check fuses check spark check power to coil check control unit live and earths check cranksensor with multimeter for signal if you just swap parts around you can lose yourself in trying to find the problem when it can sometimes be something straight forward Share this post Link to post Share on other sites
All Praise The GTI 3 Posted May 23, 2008 how do i check the coilpack and ignition module? which pins etc? thanks for the tips Share this post Link to post Share on other sites
pug_ham 242 3 Cars Posted May 23, 2008 can i take another CAS of some other pug to try? are they all the same?the 6 fuel realy looks the same and fitts ok could the ignition module be at fault or my coilpack? the engine ran when removed but i guess something electrical could of died while it was in my garage? CAS; usually the same & one from any Pug or Citroen should work. AFAIK the GTI-6 double injection relay is the same so it ought to work. Check the part nubers stamped into the case, if they match you'll be fine. Ignition amp / coilpack; It could be either of them stopping the spark Pin 4 of the coil pack plug should have 12v from the double relay (pin 1) with ignition switched on & there are two wires that run between the coilpack plug & ignition amp (coilpack plug pins 1 & 2 with ign amp plug pins 1 & 6 respectively). Pin 13 from the relay should send power to the injectors. Pin 4 from the ign amp should be earthed, if it isn't so you won't have a spark. Graham. Share this post Link to post Share on other sites
