I have a 2000 Dodge Ram 1500 with a 5.9L. In December the RE46 transmission failed so I put it in my garage. Over the winter I removed the transmission and rebuilt it. After putting it back in and hooking everything up it had been about 5 months. IT WOULD NOT START. The coil doesn't have 12 volts. The coil is good. I unplug the 2 wire connector hook my test light have my wife crank it the light will flash once. Shut off the key switch try again same result.Replaced crank and cam sensors.I think I installed the crank sensor right. I don't have a any tack.
Thanks
Have you checked powers and grounds to pcm and the volt ref wires from pcm to cam and crank sensors? Not to mention as well as grounds for the sensors and any ground straps that may have been removed while taking out trans?
I'm in the process of doing more checks on 5 volt now. I did check for any ground straps or wires that might have gotten in between the bell housing and block. Thanks

Here's where I'm at : I have 5 volts at all my Sensors and such, but I also have 5 volts coming from my crankshaft sensor. I have removed it and am waiting for another one to come. Is it true just put it in and bolt it down????
I understand you`re measuring 5 volts on the sensor`s signal line. That`s per se does not indicate a faulty sensor.
If you see the 5 volts at the connector with the sensor unplugged you probaly are dealing with a pull down design. In his case you could connect the sensor and turn over the engine slowly by hand and watch out for the 5 volts to go to ground, depending on the position of the reluctor/trigger wheel.
If you measure the 5 volts only with the sensor connected it still might be normal, as it could be a pull up design, depending on position of the reluctor. Again measure the voltage on the signal wire while turning over the engine slowly by hand, in this case it also should fall periodically close to 0 volts.
If I understood you correctly the coil is missing the power feed. Did you dig into this issue? (I suppose the test light was hooked to bat+ on one side and the other one was connected to the coil control wire)
An expert is someone who knows each time more on each time less, until he finally knows absolutely everything about absolutely nothing.

Being a Dodge I understand it is a pull down sensor, so I failed to say that I was turning it by hand and I had a steady 5 volts when it should be pulsating (off and on) as the flywheel turned.
I finally found the right crank sensor, called my local Dodge dealer he gave me a part number because the part had over 400 back orders. So I got it in today and it fired right up, Thanks
