Here is the deal. My passenger side cylinders aren't firing. The injectors are tested fine, the timing and compression are fine. I have the grey booted f.i. injection harness toward the front of car and the black boots on the rear injectors. If I take off the injector harness on driver side cylinders then you can tell that the engine stumbles. If I take them off the passenger side I don't notice engine stumble. The passenger side exhaust pipes do warm up some as you let engine idle but not hot like driver side h.e.
Where do I go from here? I will trade the passenger side injectors to the driver side to make sure they work but then what? I did replace the injector harness, brain, and passenger side injectors out but that didn't change anything. I am getting 12 volts out at injector harness. Should I check the grounds? Could the grounds for the passenger side not be grounded properly? Is there a proper way for the f.i. harness to be connected to the injectors? I can turn the harness 180 degrees to the injector. Sort of like placing the connector upside down and still connect into the injector. Does this affect the injector in doing its job? I am sort of lost here. Thanks, Buck |

Check your injection trigger points.

QUOTE(Travis Neff @ Jun 18 2007, 04:41 PM)  Check your injection trigger points. Why? He said the other side works fine. Check the grounds under the intake manifold. There are several there, and they can loosen. They're on a case through bolt near the flywheel end of the top of the case. The Cap'n |
