hello i guys well for start i have a 1993 FD , i been delaing with this problem over 2 months know, the car is completely stock only this that has is a apexipower fc and non-sequential turbo sistem, the problem is the follow, the car cranks but dont start i check fuel pump and its ok, change for a new map sensor and nothing, new crank angle sensors and nothing a friend of mine borrow me his igniter and none, replace complete coil package and nothing today i check all the fuses and seems to be alright, the funny thing is that the car was running ok and suddenly turns off on the highway and the problem persist till today, i have a power fc and the pfc commander doesnt even start is completely off also try with the stock ecu and nothing, im really desperate i dont know what else to do. i dont know if is flooded or maybe there is any electrial issue but the ost concerning thing is that the power fc doesnt kick in not even the apexi logo is like it was fully disconected im about to cry really

thanks guys hope you can help me.

 

Sounds like you might be losing power to the ECU. Have you checked that?

 

Did this happened after the PFC install?

My FD refuses to stay on with my PFC... still haven't figured out why...

Dennis,

 

Double check the 30A EGI fuse and EGI Relay.

 

yes i have check the ecu has power thats why i dont now why thisis happening.
i will check the fuse and relay to see...
no the power fc was already install maybe im thinking if some grounding maybe loose or something

if you guys know what grod points are critical to `proper engine function let me know

 

send you a PM with a pic of the one that always screwed me over hard time.

 

this ground did the exact thing to me after i installed a new motor. hope you can see where i circled. it would actually connect from th UIM to the Firewall
