hey, was wondering if anyone can help me out with a bit of a prob.
still no spark in #2 and #3 cylinders. All other cylinders have spark

Coil has 3 wires, Red, black, trigger/signal
Red im reading battery voltage, black has good ground, and trigger on the 2 bad cylinders are about .3 volts. All the good cylinders read about 3 volts. Now what can cause this?

we've already swapped a good coil in, so its not that, swapped the ECU, contiunity between ECU and coil is good. Crank and cam sensor circuits seem fine as well. Im all out of ideas....can anyone offer some help? so close but yet so far...cant drive the stupid car.

 

any tips?

 

Are you using a digital multi-meter for your circiut tests? The signal voltage on the good coils seems a little high; my '99 FSM indicates that you should be getting between 0.01-0.1V to ground. It sounds like you have checked everyting except the condenser. Here are the 2 pages from the FSM for doing an ignition sigal diagnosis.

Good luck and keep us posted on your results.

 

thanks for teh post....thats weird...
im using a SnapOn digital multimeter. I also have a SnapOn diagnostic scan tool that im using. we alreayd checked the condenser...its ok.
