i gots no spark. someone give me a rundown of what to check, please. clearly, im a nube, and probly shouldnt be working on a car..
 
idk for sure how to test but check your main fuse in outside box if thats ok then its igniter chip, keyssr had same problem and it fixed it. or its your cam angle sensor. but check for pulse on a coil pack first.
 
first off, ive been searching around and found it could be the cas if its not the ignitor, but would the cas cause me to have no spark in all 4 plugs? and im sorry, but what main fuse are you talking about? and how do you check for coil pack pulse?
 
on the fuse its the i believe 75 amp in the fuse block.

that why its probly your igniter chip.

checking pulse if i remember one is power and one is pulse from the computer and other is ground

Click to expand...

its prob your ignitor and you check coil pulse with a tast light 1 has 12v other has G and the other one has a pulse of G or 12v/5V
 
well on the coil pack, theres -, +, and E

i take it E is the pulse youre talking about. like the coil signal from the ecu/ignitor. but i dont think any of them are getting spark, but ill check things out better tomorrow.
 
i.

but it cant be that. i did just what they told me on frsport.

and i cracked the ignitor open and it looks like 3 of the 4 solder joints are bad. im hoping thats what it is..
