I have a 1.8t in a caddy using a qpeng ecu with an intermitent starting problem as of yesterday. It has always started easily but yesterday about 10 mins after stopping it would not start . There was no spark( engine turning ) but there was power to the coilpacks injectors etc. It started about an hour later then drove home without a problem then would not restart .There is also power going to the sensors but there does not seem to be power going to the crank trigger ( 0.02v ) There is continuity from the plug to the ecu circuit board on the yellow and white wires but cannot trace where the black wire goes . Has anyone got any ideas or have a wiring diagram or pin out for this ecu ? Thanks in advance
