Jamesn Posted December 29, 2022 Report Share Posted December 29, 2022 Hi guys, woundering if anyone could help me have an rb20det in my mini truck has a link g4+ atom ecu, wastespark, megasquirt ignitor and powertune dash. I have had some problems of late regarding fueling but i have nearly solved this problem with my regulator and injectors needing cleaning but my next problem is the engine wont start at all or fuel fan and ignition relays wont click on I have tried plugging ecu in computer and comes up with "unable to connect to the ecu but usb connection is present. Please cyce the power to ecu" i have a blue led that comes on ecu so im pretty sure that it is getting power and swapped the relays still nothing except when i disconnect the ecu relay ground my fuel pump turns on, but now im noticing my ignitor on the outside is very hot to touch and also my coil pack is hot to touch, previously had spark before Also before i could spin the crank sensor to test the injectors and the fuel pump would turn on but now nothing like that seams all power is dead or is shorting out somewhere. Any help would be appreciated- havnt had any heating issues of coil packs or ignitors before. Cheers James Quote Link to comment Share on other sites More sharing options...
