00 Dodge Ram 1500 Sport 4x4 5.9L engine swap No Spark
the 2000 Dodge Sport in the title you guys have already heard about it's the one that purged all the tranny fluid driving down the road. I am now swapping the five nine from the original to the matching engine for the transmission that I put in I installed it just last night and I worked all day on it today trying to get it to fire up and I get crank I get fuel but no spark anywhere. I've changed out the coil, I've changed out the distributor, I've changed out the distributor plate that the cap sits on, changed out the rotor, the plug wires, and the distributor cap. I've also checked all grounds, I've even replace the crankshaft sensor with the original one knowing that it worked when I pulled the original motor out. I still have no spark what-so-ever I keep getting the same code over and over again of a p0320 no crank reference signal at PCM. I have checked all the wires there's no breaks, there's no corrosion, no cremped (smashed wires) I'm completely lost I need some direction or advice on how to get the spark back in the engine.there is fuel fuel pressure everything I have even purged the fuel system to make sure there is no air in the fuel rail.
That P0320 is your problem. PCM needs both cam and crank sensor signals for the engine to run. That one seems to specifically refer to the crank sensor, so, no ambiguity there at all. Since you swapped the sensor, and still have the same problem..... Did the flex plate you installed on the engine have the 'window ring' for the sensor to read? I am going to assume that it is the correct sensor for the trans.... (there is a difference between auto, and manual trans...) Are you getting 8 volt reference signal at the sensor?
I've been working my way aroundthe electrical system mostly at this point at the ignition coil at the front of the block because I didn't know what the crank voltage needed to be now where would I take that measurement from would it be at the plug or would it be at the PCM
This is in response to what you were telling me to try. Crankshaft position sensor (Female side of the plug) to the truck harness (Male side) I'm going to be reading you the settings and the measurements and pictures will be included but the only reason I'm reading it is because the settings are blurry in the photos starting with the black probe is going to be center wire on female end red white red probe is going to be on either side of the black crow on the female and starting measurement is going to be voltage 200m measurement is going to be (95.7) second setting is voltage 2000m and that measurement is going to be (095) next setting is voltage 20 and the measurement that I got off of that is (0.10). Next are different, the second set of measurements are going to be in Omes, starting at 2000 ome that measurement is going to be ( 457) next measurement is going to be ome 20K (1.04) the next measurement is going to be ome 200k (06.9), and the last one is Omes 2000k (065).
I'm having issues with the pictures not loading here so I will send them once I get the error fixed.

Not to sound like a Jerk but i have no idea what you are talking about here...
You need to check(ground and reference voltage) at the plug that goes into the crank sensor. Don't know witch is witch off the top of my head but you should be able to figure that out with a VOM(volt ohm meter). Also needs to be set on approximately 50 volts DC scale for voltage readings. Should be three wires, ground,reference voltage and the wire that sends the signal back to the pcm(You need to have the sensor plugged in to check this). Or if you have a scanner that reads live data you would be able to see if the pcm is seeing a signal from the sensor.
starting measurement is going to be voltage 200m measurement is going to be (95.7) second setting is voltage 2000m and that measurement is going to be (095) next setting is voltage 20 and the measurement that I got off of that is (0.10).
And for anybody that has been checking to see if the issue is fixed it's not. I've been on this truck last few days that's why this post has been quiet I've been digging through this truck ever so diligently looking for this issue and I ended up finding total of 8 wires that were damaged righr across the main portion where the engine sets from engine swap but I still have the same code which is p0320 and even with those wire's fixed everything else is still reading the same code I'm wondering if anybody might have any suggestions as to where I need to go or what I just recap every place cap and rotor in tire distributor plug wires coil packs for the ignition coil at the very front of the engine I've gone in I've repaired grounds of chick grounds are chicks make sure each individual unit is getting their signals and their proper voltage is I've checked fuses and relays it just cranks and cranks and cranks but it's not firing at all I really do need some guidance and some help on this so please get back to me as soon as possible thanks and can anyone help with a full TSB report the TSB #082400 it's the same issue I'm having but I cant find the full report anywhere

If you are not getting spark, that's the crank sensor. If you have replaced the crank sensor, all the wiring tests good, and still have no spark, time to look at the PCM.

Hey Thomas, the crank sensor is just behind the distributor (near the firewall, up top of the transmission). Sandwiched between the transmission and the engine. Its really ****ty to get at and change out. My guess is that sensor isn't plugged in or you have damage.
