I have power to #3 and #4 injectors but not #1 and #2. The car will run but it is missing on 1 & 2. I have spark but when I pull the wires off the injectors nothing happens. After testing more I found I have no power to both of them. Where does the power come from? Do I need to look at the releasing contacts at the base of the distributor?

Actually the injector groups as the ECU see them are:
1&4, 2&3, diagonally across the engine. Their shared transistor would only see a 1 fuel injector load at a time when one of them fires as controlled by the trigger points, making most efficient use of that transistor, but the ECUs rarely are a problem. Injector pairs 1&2 and 3&4 share a common ground. So depending on which pairs of injectors goes down, suggests a look at either the grounds or trigger points. |
