shorty Posted January 16, 2013 Share Posted January 16, 2013 You defo sure its not coilpacks? They are common fault and also try fuel pump as my mates s13 developed a missfire just befor the fuel pump died. His best bet is to burn it claim on insurance and buy a starlet hahahaaaa hate nissans lol Quote Link to post Share on other sites
akyakapotter Posted January 16, 2013 Author Share Posted January 16, 2013 Yeah man we have checked the coil packs so many times its fine from cold asoon as its hot and turned off and back on again it starts playing up he would do that but it's to nice to burn look lol Quote Link to post Share on other sites

StuDoc 72 Posted January 16, 2013 Share Posted January 16, 2013 (edited) Coil packs get a set of spitfires on there. £250 but well worth it. They have the strangest symptoms of them going. They can work fine for ages then be intermittant. If its not that then its the CAS sensor. Fuel Pump ECU Im going from working on an RB25DET but they are pretty much all the same.

akyakapotter Posted January 16, 2013 Author Share Posted January 16, 2013 We have just ordered a fuel pump and a replacement set of injectors going to try that first then it will be yellow jackets he's going to go for I'm currently talking him into getting it niss tuned Quote Link to post Share on other sites
Flaminsam Posted January 16, 2013 Share Posted January 16, 2013 Sr20det engines are usually spot on apart from the bottom ends failing if the oil isn't changed at regular intervals. Again I would be looking into coil packs. Unlikely to be injectors as the s15 use the side feed injector and have a fine gauze all the way around them. The crank angle sensors are also common but doubtful. Has he done the blink check on it yet? See if the ecu has any faults? Also this may sound daft but check the inlet piping. With these engines using a maf any unmetered air entering the engine can cause the fuelling to be out. Even a split vac line to a solenoid etc can cause havoc. Quote Link to post Share on other sites
akyakapotter Posted January 16, 2013 Author Share Posted January 16, 2013 Hey bud yes we had it on a snap on reader it brought up code 27 which was ignition signal but we think that was because of the alarm disabling the ignition system with the imobliser have replaced all the vac lines checked all the intercooler pipes they are all fine maybe the standard dv is fooked and sticking open or something.

CA's are similar to RB's. SRs are pretty different. Sr20det engines are usually spot on apart from the bottom ends failing if the oil isn't changed at regular intervals.

Bottom end failure is not that common, but it happens when folk buy 100,000 mile engine and drift them thinking they are fine. Have you asked on the one place I bet you'll get an answer? The SXOC. Also, who is gonna map his Nistune set up? Don't go near FC Tuning, guy doesn't have a clue. Edited January 19, 2013 by Rubix_Cube Quote Link to post Share on other sites
akyakapotter Posted January 19, 2013 Author Share Posted January 19, 2013 No mate he's not a member on there ill get him to join up Quote Link to post Share on other sites
Rubix_Cube Posted January 19, 2013 Share Posted January 19, 2013 Search the S14 tech section, the S15 is just an S15 in a pretty dress. The engine and stuff is all the same, in a manor sorts.Things I would check from my experience isAFMIgnition Amp (sits opposite the turbo and can get hot and go faulty)CoilsPlugsCASGet known working ones and swap them out The ignition amp is a common one.
