been working on my fc for four months now and cant get it started. compression check is good. fuel pressure is good. no vacuum leaks. the only problems i can find is i get a spark buts it seems to be very weak. i also do not get an rpm reading when cranking. engine cranks fine but will not fire. I also cannot smell any gas even if i take the plugs out and crank it with all the fuses in. i checked the resistance on the injectors and they are good and i even swapped them for a known good set and still nothing. Seems to be an electrical problem somewhere but i dont know where to even look anymore. Engine is ported, 3mm apex seals , no emmissons controls. Apexi Power fc (I've tried starting it with the orginal ecu as well with no luck). ANYONE HELP PLEASE!

 

Have you check the relays?

 

yep, i do have fuel pressure i just dont know if the injectors are firing. or if its an ignition problem. its something electrical i just dont know what

 

if you got a spare cas connect it to the harness but dont install it and spin the gear and you should here the injectors clicking. if they dont click there probably stuck

 

bump. injectors click
