Got it out a few weeks ago and it wont start. It will start when you fog the intake with starting fluid. Im going to start testing fuel pressure. first after the pump, then after the filter, then after the regulator. I don't have a noid light to check the injector signal, but they are grounded.
any ideas?... thanks! (IMG:style_emoticons/default/driving.gif) |

Start mode and pump are on the same trace on the relay board. If starter is working, ignition switch is good.
ECU causes a ground to be at the fuel pump relay pin 86 on one of three conditions, 1- when ign. sw. to on, pump to on for 1.5 sec. 2- when starter is engaged by ignition sw. 3- whenever engine is turning over at 100 RPM or greater. Tom |
