so finally installed engine have brand new Leading/trailing plugs along with new wires and using exsisting coil packs...when i pulled the engine 6 months ago they worked fine and now im turning the car over and nothing..can they just go bad like that or is there a ground or something that im missing? there is power going to both of them tested already.

 

i dont know. it could be something with the airflow meter, as i have had problems such as this before.

 

couple things
when you connect your battery, you should hear a "clicking noise" do you hear this? i think your key has to be in the on pos.

check your afm connections. also, i think aaron has a cool method of checking to see if spark is actually being sent to the spark plugs at the correct time.

also check ALL of your grounds and especially fuses in both places.
check your timing as well??

 

Have you actually checked for spark by pulling off one spark plug wire, putting any spark plug in it and getting a friend to crank the car while you hold the body of the plug on the engine (or other good ground)? If you haven't done this, what have you done to conclude that there is no spark?

 

no i have actually pulled all plugs and went one by one grounding them and looking to see if any spark but notta

 

Hmmm... well i'd start by looking at the leading since it is simpler and the car really needs it to run (it can run fine without the trailing, it will run very poorly without the leading). The leading has just 2 wires plugged into it, constant power (12v) and trigger (to ECU), ground is through the body of the coil. Since both aren't working, I would suspect the ECU isn't getting a signal from the CAS. Make sure it is plugged in at both ends.
