rinart Posted August 28, 2009 Share Posted August 28, 2009 (edited) Hi was wondering if anyone could help with this issue, I've just done a rb20det conversion wired it up and its not starting, I've read quite a few threads with people having the same problem but nothing I've learnt from there has got mine going. It's getting spark , the two green relays by the ecu are clicking, the fuel pump is working on que with fuel going through the system and returning back to tank, check the plugs and there dry as anything , The fuel lines are the correct way around, i can put fuel down the intake and it runs for a little, So im left scratching my head the only thing I can put it down to is the injectors not pulsing and i dont really know were to go from here. Any help would be appreciated CHEERS. Edited August 28, 2009 by rinart Link to comment https://www.sau.com.au/forums/topic/285492-rb20-not-running/ Share on other sites More sharing options...

StealthX Posted August 28, 2009 Share Posted August 28, 2009 injectors... i guess just check they are wired up properly. have they been tested/do you know they work for sure? are they standard and what ECU are you running? its def and injector-related problem, so give me EVERY bit of info you have on them... whats the motor going into?

Its in a hilux, im not sure if there working for sure i cant hear or feel them clicking when cranking The fuel rail is after market, not sure on injectors ( not to familiar with rb's yet ) but there red if that helps. Running standard ecu . Thanks. Link to comment https://www.sau.com.au/forums/topic/285492-rb20-not-running/#findComment-4794479 Share on other sites More sharing options...
StealthX Posted August 28, 2009 Share Posted August 28, 2009 bahaha f**k me thats a good motor swap! well done! ahh yeh injectors... stock RB20 injectors are a darkish red... they flow 270cc if my memory doesnt fail me. (sorry i do x-trails, not really skylines) if they're not clicking, then they arent working. they could be blocked, or not communicating the the ECU correctly. my money's on the latter. take em to a performance shop or anywhere that does testing to see if they actually work but for now i guess just double check they are wired in right. grab a volt meter and check to see if the terminals on the injectors are getting current, and with no interruption. where you get the motor from? a front cut? do you know any history of the motor?

James_03 Posted August 28, 2009 Share Posted August 28, 2009 Injectors are gummed up I bet. Has the motor been sitting for a while? Because if it is the injecors are probably just gummed up. Take the CAS out, keep it plugged in and get a mate to turn it over same direction as cranking with IGN on. Then grab a screw driver and hold it against one of the injectors bodies and put your ear on the end of the screw driver. Should be able to hear it pulsing throught the screw driver when turning the CAS over. If nothing then check your 12v constant on the injectors, out of the 2 wires on each plug/injector one will be the same colour on each, this is your 12v. With the IGN relay on, you should be getting 12v on this wire for each injecor before cranking. If your voltage is OK, remove the rail and tap each injecor body lightly with a screw driver until they start pulsing. I usually leave the rail plugged in when doing this, as you can hear them come in. If your missing 12v from the injectors, then there is a large plug near the AFM side with 6 or so spade terminals on it, one of the spade terminals gives the injectors 12v, I think it's a light grey colour. Get a multimeter and go through each spade terminal until you find it.

Its been sitting for a good 18 months so im hopping injectors are just gummed up like you said. Il give all of the above a shot first thing in the morning. Much apprectiated guys!

blind_elk Posted September 4, 2009 Share Posted September 4, 2009 Was informed im missing the injector ballast off the harness , didnt even realise so hopefully should bang up this week some time when i get hold of one!RB20 doesn't run ballast on the injectors. Unless the previous owner fitted GT-R injectors. Link to comment https://www.sau.com.au/forums/topic/285492-rb20-not-running/#findComment-4809166 Share on other sites More sharing options...
