ok any way here it goes. the car was idling and i was waiting for her to warm up and i give it a little rev to like 3k then it just falls all the way to 0. nothing crazy just died. the car has been running great the week before this. car didnt start back up right away and when it did it sounded like it was running on one rotor. so i pull the plugs, wet with gas... sweet! so here is what i check



pull plugs out and press them against frame, no spark.

all the plugs are in good shape.

replace leading and trailing coils (stock, with mazdatrix wires)

check all fuses

open up halwin, the haltech is seeing trigger events. they add up steadily as i crank. it is seeing a 200-300 rpm range while cranking.

battery voltage is 11.97

i pulled of the plug at the coil and checked for any voltage on both prongs. yes they are both getting some sort of voltage while cranking.



pull the plugs out still and hold them against a known good ground, NOTHING!!



what could be wrong with it... i was thinking it might be my power/driver side harness but as they are getting voltage i dont think that would be it. but it is not in the greatest shape. but that doesnt explain why it just randomly happened when the car was running.



help!



thanks-

weird, you try new plugs? i had a problem with my e11 where the output side of the ecu would lock up, so it would still boot, all the sensors and stuff would show up etc etc, but just no outputs.

didnt try new ones, but the current ones look almost perfect. how did you get your e11 to un freeze? i thought it might be that but im getting some kind of voltage at the coil from the ecu. i obviously can measure it cause i just have a dmm but haltech is sending SOME kinda signal



oh and to add to the things checked. i cleaned all the spots where the coils bolt to the frame incase it was a grounding problem.



every thing points to bad coil but how would it be possible that 2 sets of these coils were dead... i thought these things never died!

power cycling it usually worked, if it didnt, then letting it cool off did (e11's run hot), if that didnt work we reloaded the firmware...



also if you saved a map or something, it doesnt always save the settings correctly, might wanna have a look at that page too

yeah its been powercycled alot maybe ill try reloading the firmware...



yup i have checked all the ingition settings a couple of times now https://www.nopistons.com/forums/pub...#>/biggrin.gif

odd, its all 4 plugs right? if you draw a tree out on papre; plugs->wires>coils->ecu etc, its either the main relay or the ecu....



are you getting fuel?

yup all 4 plugs are covered in gas when i pull em



the plugs are good

the wires are new mazdatrix ones

this is the 2nd set of coils

they are getting power

they are getting some sort of signal

the haltech is seeing good rpm and trigger events

the tach is bouncing like it should

there is a voltage going to the coils from the ecu when cranking (unknown but a moving voltage was seen with a simple dmm)

good call... i will try and figure out exactly how to do that and check em out.

if the tach bounces, its sparking...

yeah thats what i would think to... to bad when i pull the plugs and put them against some thing i dont see any spark....
