MINISTARLET Posted August 17, 2015 Posted August 17, 2015 Hello all, I am in the process of building a Startlet turbo mini and require all the wiring diagrams i can get.......Currently the vehicle cranks with good fuel pressure but does not spark.The coil is earthed out correctly and all parts came off a working starlet turbo.The donor vehicle which a blown up engine I aquired was a converted auto to manual jobby, but unforuntly i did not get the ecu which i was promised.I the purchased another engine, loom and ecu for a manual starlet ( This loom was butchared by the scappy so i had to use the auto loom from the orignal.)So basically im suck with an auto loom with a manaul ecu, swapped over all modules but the vehicle will not start. So basically im asking for any diagrams people have for manaul or auto Starlet turbos/ Glanzas to try to progress my project. Please help =]Or if you live near to colchester and want to lend a hand pm me. Kind RegardsAdam Quote
morgey Posted August 17, 2015 Posted August 17, 2015 Have you bridged the neutral start switch on the ecu? Quote
MINISTARLET Posted August 17, 2015 Author Posted August 17, 2015 (edited) Would that still affect it as the ecu is from a manual not an auto? Edited August 17, 2015 by MINISTARLET Quote
StuDoc 72 Posted August 17, 2015 Posted August 17, 2015 I dont think an auto ecu would have any differences in the ignition in comparison to a manual its still the exact same engine. I think you need to look elsewhere for your issue. What about you coil, rotor arm, dizzy cap, king lead?? What about fuses? Quote
MINISTARLET Posted August 17, 2015 Author Posted August 17, 2015 Fuses are all ok, Checked with power probe and visally inspected as can never be to sure.Found a wiring diagram and the netural switch is in the same place on autos and manuals so should be fine.Got two coils and two sets of leads, dizzy appears ok.Ive got to be missing a pcm ground somewhere..

lukEp Posted August 17, 2015 Posted August 17, 2015 There is an earth on the inlet manifold make sure it's attached. I had a manual ECU and auto loom in my starlet and worked as should. Quote
MINISTARLET Posted August 18, 2015 Author Posted August 18, 2015 Correct me if i wrong but if the fuel pump relay is not switching would it then cause the no spark issue? Quote
MINISTARLET Posted August 18, 2015 Author Posted August 18, 2015 If its not possible why does the fuel pump relay have a pcm connection for fuel cut off which would then disable spark and injector pulse? Quote
StuDoc 72 Posted August 18, 2015 Posted August 18, 2015 Pretty sure it cuts the fuel not the spark. Quote
Stu Posted August 19, 2015 Posted August 19, 2015 As Morgey suggested above, make sure you have 12v on the NSW (and STA pin for that matter) when cranking. Assuming the ecu is powered properly, if you removed the dizzy and spin it by hand do you hear the injectors clicking, get the coil sparking and the fuel pump should run? Quote
MINISTARLET Posted August 19, 2015 Author Posted August 19, 2015 Ok, well nsw only has 12v at crank, sta has 0.31volts so thats not working right, but fuel pump is when vehicle is cranked which would suggest the circuit is fine Quote
Stu Posted August 19, 2015 Posted August 19, 2015 STA needs 12v when cranking so connect it to the NSW wire. STA triggers the ecu that the engine is cranking and it adjust timing accordingly before releasing to the normal ignition map. For example a 20v 4age will run like a bag of dicks if this is not wired up. Quote
MINISTARLET Posted August 19, 2015 Author Posted August 19, 2015 I lost my rag and pulled the loom off completely, fittes the other loom i have and it now fires up =] rwdrev i will take some picw for you =] Quote
JDMfreak Posted August 19, 2015 Posted August 19, 2015 Look forward to seeing these pics of this sounds interesting Quote
rwdrev Posted August 20, 2015 Posted August 20, 2015 I lost my rag and pulled the loom off completely, fittes the other loom i have and it now fires up =] rwdrev i will take some picw for you =] nice. was thinking on doing this conversion myself Quote
MINISTARLET Posted August 20, 2015 Author Posted August 20, 2015 if you do decide to do this conversation be aware you will need custom made driveshafts or access to a wire eroda and a decent engineer like i did. =] Quote
rwdrev Posted August 20, 2015 Posted August 20, 2015 handy with a welder, pair of snips and soldering iron. lol as bought following nightHalf way through the rebuild(not a good pic) but 11 weeks later, alot of welding and alot of hours spent on it Quote
MINISTARLET Posted August 21, 2015 Author Posted August 21, 2015 Nice dude, looks like you have put alot of effort in =]Is the last pic as it currently stands? still got a stock engine? Quote
rwdrev Posted August 21, 2015 Posted August 21, 2015 cheers. no, its stripped again and has been for the past 3/4 years, lol. hope to get it resprayed again next year ready for the rebuild (again) lol. yeah standard 1275 with inch and a half carb and full maniflow system, hi-lo's etc. tho might go clubby front and 4efte yet Quote
MINISTARLET Posted August 24, 2015 Author Posted August 24, 2015 If you want to see it running go here https://youtu.be/blEYqm1rxz4Will take some good photos soon just didnt have time to push it out of the dark garage at the weekend. Quote
