spark and ingector problems!

[RBARMY]

ive been building my rb20de+t laurel for about 3 months now and its driving me mad. i used my brothers wasted spark setup about a month ago and it ran sweet chopped 3rd and its just went duuuu and strarted missing. so a few weeks later i bought me a new wasted spark. his one still went sweet in his cefiro so nothing broke i put the new setup in my laurel and it barely started. ive checked the whole loom for cut wires everythings sweet. i checked all the injectors and the all pulse when i turn the cas. but when theyre all pluged in im sure they dont all click????? and prity sure im getting spark to each cylinder to. have tryd diffrent ignitor packs to no diffrence!.

can anyone help me thanks!!!

ohk am definetly getting spark got a huge shock when i spun the cas had to put screw driver in because couldnt see it arcing out. sprayted engine start in and it starts for a few seconds somtimes. injectors again? checked all of them again they all seem to be going. is the some type of signal wire to let them work when u turn the key so they actually squirt???????????

[RBARMY]

held the injectors in and took the fuel rail of and all injectors will squirt at once!?!?!? then like 3 or sumthing then all again or 2 or idk weird fireing rate but doesnt start at all!!!!! am going to get new loom hopefully thatl work and sus it out!

I would say check the ECU! cause the signal thats coming telling injectors to pulse is coming directly from the ecu! check for a short? Search for continuity by unplugging the ECU from the harness look up the RB20DET ECU pinout and check the injector wires for continuity there should be only one wire continues between all the injectors and thats the 12V injector wire the rest should be on there own. So check that also!

spinning the cas and having all the injectors fire, then a couple, then one at a time in order is the same as mine does. i think for startup thats how its supposed to be.

hey o true sweet i think it done all 6 then 3 and the otherside 3 but yea dont know why its not starting. but they all fire at different times after thatin the rong order. am going to get a new loom had to connect heaps of stuff when i got it so its probably buggered or idk somethings wrong. hadto bipass the relay for sum reason a guy i knew done it but he died in a car crash so dont have a clue how to fix it or find out whats wrong!!!!!cheers!

Just bought a new loom so hopefully thatl fix the problem because i tryed a diffrent ecu and that didnt work so loom must b buggered. and had to join heaps of wires at the start so yea hopefully its gonna work!
