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) |

There is no fuel pressure sensor. Either some DAPO hot wired the pump, or something wrong in the wiring to the ECU or bad ECU,bad injector points, or bad relay. My guess is DAPO. Should have 28PSI pressure. You can't guess at it, has to be very close.
There are two sets of points, one for ignition, one for the ECU to trigger the injectors and fuel pump. If you indeed have spark coming out of the coil, it goes through the wire, to the distributor cap, through the rotor and back to the cap. Ignition points only control the coil. |
