88pathoffroad Posted December 9, 2007 Share Posted December 9, 2007 Have you run the ECU error codes to see if any errors are stored just in case? Link to comment Share on other sites More sharing options...
k9sar Posted December 9, 2007 Share Posted December 9, 2007 are you checking for 12v at the coil while it's being cranked? A bad connection could give you 12V with no load but be open or weak when loaded. Shouldn't drop below 9V or so during cranking. When you see the weak orange spark, are you throwing a plug on the coil wire and taking the distributer and plug wires out of the loop? It is possible that you could have replaced something bad with another bad one. Link to comment Share on other sites More sharing options...
nissan4x4 Posted December 9, 2007 Author Share Posted December 9, 2007 yes i have tried taking the coil wire and putting a spark plug on it and got a good spark of off of the coil.and ill check what the volt is under cranking. Link to comment Share on other sites More sharing options...
94extreme Posted December 9, 2007 Share Posted December 9, 2007 yes i have tried taking the coil wire and putting a spark plug on it and got a good spark of off of the coil.and ill check what the volt is under cranking. then maybe it's something in the dizzy.. there is a sensor built into it and it sometimes does go dead.. check the erorr codes as the ECU should definitely flash coded related to that sensor.

nissan4x4 Posted December 9, 2007 Author Share Posted December 9, 2007 this is a pretty new distributor we get good spark out of the coil but out of the distributor we get a weak orange spark Link to comment Share on other sites More sharing options...
94extreme Posted December 9, 2007 Share Posted December 9, 2007 read the last part of k9's post.. then check error codes. Link to comment Share on other sites More sharing options...
Simon Posted December 9, 2007 Share Posted December 9, 2007 Check the ground to the distributor. Also replace the cap and rotor. Link to comment Share on other sites More sharing options...

Slick Posted December 9, 2007 Share Posted December 9, 2007 i got error code 21 what does it mean and how do i fix it error code 21: ignition signal Link to comment Share on other sites More sharing options...
nissan4x4 Posted December 9, 2007 Author Share Posted December 9, 2007 this morning i went to the truck to get the error codes and the truck almost started very weak though.and could the timing be off so much it could cause this,because when i put the replacement dizzy in i got as close as i could get to the original timing on the old distributor.

88pathoffroad Posted December 9, 2007 Share Posted December 9, 2007 Dude, as close as you can is NOT where it needs to be. You have to have that thing put in the EXACT same way the old one came out or your spark timing will be so far off you won't be able to start it. Best bet: find TDC for #1 cylinder at compression stroke, then check to see where the rotor is pointing on the distributor. It needs to point like this on the V6: Link to comment Share on other sites More sharing options...
nissan4x4 Posted December 10, 2007 Author Share Posted December 10, 2007 whats TDC im a newb to all of this. Link to comment Share on other sites More sharing options...
Roost Posted December 10, 2007 Share Posted December 10, 2007 whats TDC im a newb to all of this. TDC is Top Dead Center which means that cylinder #1 is at the top of the stroke and crank and cams are lined up. It is the base line for all that is related to tearing down an engine and putting it back together, to include a timing belt replacement. Hope this helps Link to comment Share on other sites More sharing options...
Roost Posted December 10, 2007 Share Posted December 10, 2007 It is also where you need to have the engine when you replace the distributor. Unless you marked where the "dizzy" is located when removing it and replace the exact same way as you removed it. Link to comment Share on other sites More sharing options...
Slick Posted December 10, 2007 Share Posted December 10, 2007 i'll tell you a secret..... i got error code 21 today, had 2 bad injectors, and my dizzy was 1 tooth out........ 1 injector fixed, and the timing. MUCHO better, be 100% once i get the other injector changed out. Link to comment Share on other sites More sharing options...
nissan4x4 Posted December 10, 2007 Author Share Posted December 10, 2007 would adjusting the bolt on the dizzy on the base put the timing at least closer so it can at least start. Link to comment Share on other sites More sharing options...
Slick Posted December 10, 2007 Share Posted December 10, 2007 (edited) would adjusting the bolt on the dizzy on the base put the timing at least closer so it can at least start. get a timing light on it. but yeah, you can loosen the bolt to turn it some to try n make it start, but if you KNOW the dizzy is off, then readjust it and put it right, chances are, it WILL start... then you can time it Edited December 10, 2007 by Slick Link to comment Share on other sites More sharing options...

nissan4x4 Posted December 10, 2007 Author Share Posted December 10, 2007 thanks i will try to adjust the bolt and see if she starts at all Link to comment Share on other sites More sharing options...
94extreme Posted December 10, 2007 Share Posted December 10, 2007 you loosen and tighten the bolt, only.. you'll have to rotate the dizzy one way or another just a tad. good luck. Link to comment Share on other sites More sharing options...
