No Spark!! No Signal To Igniter!!
 
I'm seriously puzzled here. i am getting no signal from my PFC to my igniter therefore no spark. what could be causing this??? could my crank angle sensors be crossed? would that cause the PFC to send no signal? is there a way to monitor the signal from my CAS to my PFC??

you can check on cranking at the ecu pins whether your CAS are giving any signal to the ECU. I dont know what pins tho..youd have to look them up on the FSM. It does sound like it might be something CAS related....dyou know if the injectors are firing (ie is it flooded) as im sure they injectors wont fire unless they also get reference from the CAS.

engine is definetly flooded. i smell quite a bit of fuel. maybe the PFC isn't sending a signal to the igniter for some reason??? are there any settings in my PFC that would cause this?? the only settings i changed were the injector size and the seqential turbo control (turned off). i checked the pins for the CAS input but got nothing, but on the other hand i don't know if i should be checking for AC, DC, or OHMs since it isn't just a simple on/off switch. i did on the other hand, get no signal at the connector to the igniter from my PFC. so it definetly isn't sending out a signal.
