2001 Dodge Ram No Check Engine Light And Truck cranks but w

Welcome to the forum, thanks for the donation. If it cranks good but won't start, have a helper crank it, while you check for spark at the plugs. If spark everywhere, use a gage and check fuel pressure. You might also check for primary voltage at the coil and injectors, engine cranking.

If no primary voltage at the coil or injectors, that voltage comes from the asd relay. I'm not saying the relay is faulty, if the computer doesn't see the proper cam and crank signal, it may not ground the asd relay. I'd have to check voltage circuits at asd relay, then go from there.

I'm not sure about your test? I'd start at asd relay circuits. Terminals 30 and 86 are hot all the time, you can use testlite.

As far as the crank sensor, check the circuits with everything hooked up. Violet wire with white tracer is ref voltage-- black wire with lite blue tracer is ground-- Gray wire with black tracer is signal. Engine cranking, the signal is a dc pulse.
