NO SPARK but no codes...?

[sidewaysca18det]

so interesting problem.. i drove my car and parked it for the night ran fine. next day it wont start turns over no prob can smell fuel.. thinking its flooded for some reason i pull the pump fuse.. partial detonation... and that was it... so i checked for spark.. i had none... then checked the ecu for codes... no codes be sides a 12 which is maf sensor, which wudnt effect spark. so i checked continuety all the way from the ecu to the packs... every thing had cont. coil packs were grounded. the middle wire was getting 12v... but the signal wire was only getting about .3v when i turned it over... is this right? i aslo checked the ignitor as it says to do so in the fsm the continuety i had thru th ignitor was aprox 680 is this right i know its not supposed to be true cont.... engine is grounded also i have a ground comming rite off the metal coil pack seat rite above the plugs.. unless ur not supposed to have that grounded? anyone with ideas?

You can see EXACTLY if you have spark, is to pull the plug stick it into the coilpak and touch the tip of the plug to a screw driver, and you WILL see it spark. Then you will know for sure.... Otherwise checkk all your points of ground.

i know... and im getting no spark whats so ever

Go buy one plug from the store, don't thread it in. If it doesn't spark either, take it back, and find your problem. I doubt all 4 would fail at once though.

edit - if you have a ca18 i believe your spark plug would be a PFR6A-11

Regardless of what sprak plug, it should spark, but it doesn't seem like its sparking at all. Can you get an extra ignitor? Swap the ignitor.

so heres what i did... used 2 sets of plugs.... i was checking one ignitor that was in it and it was giving a constant 12v to signal wires... so swapped it with a ca one and tested it the way i nthe fsm came out good... volts coming from the ecu to the ignitor were between 0-5volts with the pulse... the volts coming out of the ignitor at the coils were between .2-.6 volts?? is that rite or is it too low? i was checking pulse by turning the cam sensor. i got the constant 12v going to the signal wire with my old ecu i swapped it out with a fried one... but the fried one still started my car when i took it out

Did you get to fix your problem yet? I'm having similar issues.
