Dme only firing on one cylinder - spanaz1 - 09-03-2017 Hello guys, i have a bmw e36 318 M40, i got the car without dme on it so i bought a red rebel dme 0 262 200 520, but when i try to start the car it is only firing on cylinder number 1. spark and fuel injection. i have checked almost all wiring but they seem ok now i think the dme is dead. am thinking of maybe trying to change the transistors responsible for spark and fuel but i dont know which are they, can some one please point me to the right direction....thank you RE: Dme only firing on one cylinder - CATAHA - 10-03-2017 Check timing, cam sensor, crank sensor, Wiring, EWS Check Main Ignition Coil Check ground(s) on injectors, if you Have Power Probe 4 easy Check attached picture, look for those components on ANY ECU/DME/ME cars Also sometimes when car senses that if it's off timing, if injector, if coil is not working it shuts-down per-cylinders (can be easily checked/search on v12) Check OS/2 sensors, based off OS/2 sensors readings DME/ECU determinants to open/close injectors, when and how much base or out-put/raw fuel RE: Dme only firing on one cylinder - einet - 10-03-2017 Change the Defect3ed FET on the ECU RE: Dme only firing on one cylinder - spanaz1 - 13-03-2017 Which MOSFET do I change any pic will be great |
