i think ive found the problem. i lifted the cover of the ecu and holly shit theres been a small fire in there by the look of it around one of the drivers for the injectors.my next headache is how the f...k that happened. i pluged in a indicator mainbeam dip switch it wasnt for the cossie but of a std sierra for the last mot. and about five year ago i took a power supply of the fuel pump relay on the triger wire to run another fuel pump relay when i re wired the fuel pump from the back to the fuse box i should of just found the triger wire. has anyone got a 2wd saff std ecu for a red top its running a stg1 chip. im assuming i can just put my stg1 chip in a std ecu
