Zerohour Posted August 2, 2018 Report Share Posted August 2, 2018 hey everyone i built a 5sgte motor thats on gen3 head and electronics. This is the first start up but i change my distributor to 1zz coil on plug and pnp harness. It is geting power to coils and the trigger 1 and 2 both say yes when cranking. but still no spark. i set dwell to these setting from a friend who sent me a base map anyone have any ideas?

cj Posted August 2, 2018 Report Share Posted August 2, 2018 Have you set the base timing? Can you run successful spark test to each coil and confirm the cylinder numbering matches the ignition channel (you should hear them click) Those dwell numbers should let it start. I've seen reccomendations for 1zz coils anywhere from about 3.2 @ 14v to about 2.5 @ 14v so you're in the ballpark. Zerohour 1 Quote Link to comment Share on other sites More sharing options...
Zerohour Posted August 2, 2018 Author Report Share Posted August 2, 2018 I've taken cyc 2,3,4 off. Changed main spark to direct spark And turned igntion 5,6,7,8 on. Since I have a expansion harness for it The ignition test still no spark. Turned it on one by one still nothing. I'm geting power 12v and the trigger gets 8dc volt at standby but when I crank goes down to 4dc volts. Ive change dwell even to different setting from 2 or 3 different points what I've gotten online and still nothing yet Quote Link to comment Share on other sites More sharing options...
cj Posted August 3, 2018 Report Share Posted August 3, 2018 you want to use ign 1,2,3,4 and have it set to direct spark. Not 5678. Have you wired the coils up like this? http://www.sq-engineering.com/tech-articles/coilpack-info-guide Check you have got 12v and Gnd at the coils. The trigger voltage sounds about right, remember that when running its actually spiking up and down quickly to trigger the coils so a typical multimeter will show the number jumping around or an average number which doesnt really mean much. Have you got spark edge set to rising? Zerohour 1 Quote Link to comment Share on other sites More sharing options...
Zerohour Posted August 3, 2018 Author Report Share Posted August 3, 2018 Only thing is my expansion harness is ign 5,6,7,8 were my coils are hooked up on as in the pic. Do I still use 1,2,3,4 or keep it at 5,6,7,8. And wiring is set up correctly check with volt meter again just now. I'm going to check the spark edge tommorow since had to go to work lol.

cj Posted August 3, 2018 Report Share Posted August 3, 2018 I think you should be able to get a test fire to work on ign5+ but to get the thing to actually run you need to use 1,2,3,4. These are in the factory connector but are by default wired to purge, EGR, and a solenoid that is fast idle or that accoustic intake manifold thing the later 3sge's had or something similar. If you want to keep these functions you should move them to ign 5,6,7 and change your config to match. pinouts should be ign1 = 20, ign2 = 7, ign3 = 8, ign4 = 17 so these are the wires you need to move to the expansion connector (except ign1 obviously) and then connect these ECU pins to your new coils. Check the help file for a diagram. Quote Link to comment Share on other sites More sharing options...
Ducie54 Posted August 3, 2018 Report Share Posted August 3, 2018 You need to use ign 1-2-3-4 from the main ecu plug Quote Link to comment Share on other sites More sharing options...
Brad Burnett Posted August 3, 2018 Report Share Posted August 3, 2018 1zz coils don't like dwell much more than 1.8-2ms. But that wont keep it from starting. I remember seeing a thread in this forum not to long ago of someone with some "plug and play" ignition harness that was nowhere near what it needed to be. Also CJ and Ducie are correct and you will need to use Ign drives 1-2-3-4. Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 3, 2018 Report Share Posted August 3, 2018 Coils will need to be wired to the pins below: Quote Link to comment Share on other sites More sharing options...
Zerohour Posted August 3, 2018 Author Report Share Posted August 3, 2018 Shweet I'll try first thing in the morning and give you guys feed back this forum is awesome forsure. Appreciate it guys Quote Link to comment Share on other sites More sharing options...
Zerohour Posted August 4, 2018 Author Report Share Posted August 4, 2018 sooo i tried to wire it and still no luck. Ran a spark test and nothing. so im going to try tommmrow again see if maybe im missing somthing Quote Link to comment Share on other sites More sharing options...
