Our local non-volvo small service center is helping us is trying to start our remanufactured motor. They have power to the injectors and to the coil. The crankshaft sensor checks out ok. NAPA tech line provided them a diagram of what the electrical pulse should look like on the scope for the flywheel sensor when the engine is cranking. They did not get any signal from the sensor. Great, they thought they found the problem, so they ordered a new one....same thing with the new one, no signal. He took a non volvo flywheel sensor and with his hand manually moved it back and forth his scope to check to make sure that was working and got a signal but when he does it to either the old or the new sensor there is no signal. Could it be that both sensors are bad or does any one have any experience with this or what else we can check. thanks, phil
