Hello! I’m in a little tough situation and need advice… I’ll give the whole story so there’s no unknown information. I have a 2001 dodge ram 1500 slt Laramie extended cab 2wd and i decided to put my built transmission in my other dodge for a build and wanted to put a 5 speed in mine. Well I did my own research and thought I was ready but apparently not.. I went and bought a getrag 5 speed and was told it came out of the same truck but it was a single cab… I got my transmission out and put that one in cut my floor board, grounded my neutral safety switch I got a 2 piece drive shaft and got it in and made my own cross member for the carin bearing. I got my pedals in and everything was ready. I went to start it up and it took a minute but it started up and sounded like ****… would barely keep itself running, so I put it in reverse and pulled it out the garage and it died.. now when I try to start it it will turn over really strong but won’t run or try to idle.. could that be the ecm or crank positioner sensor? Idk. The motor ran fine before I did a engine rebuild a few months ago and it never gave me any issues. It has all its fluids at the correct level and the dash will come.. there is a light on for my transmission temperature. Has anyone had this issue or similar?

 

Highly likely you crunched the crank position sensor when doing the trans swap. It is quite frequently a victim of that exercise.

I didn't think these trucks came with a getrag trans though... Thought they were all NV3500/NV4500?

 

I’m going to check that tomorrow and order a new one if that is the case. I’ll update you on that tomorrow. I was told it was a getrag but I’m not 100% I’m going to look up the serial number to see

 

so… new crank position censor and still doing the same thing

 

Is it the correct sensor? There is a difference between auto, and manual sensors.

 

if i did a manual swap and left the automatic sensor in my 97 1500 5.9 magnum would it not start at all and would it for some reason also cause the fuel pump to not work either. the truck was running fine before i started the swap and now wont start and i cant get a straight answer out of anyone why it wouldnt start
sorry i went off this thread

 

Manual swap shouldn't affect fuel pump at all, unless you pinched the harness somewhere.....

You have to jumper the neutral safety switch for the engine to crank. If you don't have a service manual for your truck, get one from here. Wiring diagrams are in section 8W. Look up the nss, and the starter relay circuit needs to go to ground there.

 

so i already have the NSS grounded out and it cranks over just fine. ive traced the issue down to not having spark at the engine but i dont have any check lights to reflect it either

 

PCM doesn't know if the crank sensor has failed, it can see an intermittent problem, but, if it's just bad, PCM doesn't have a clue. Did you remove the crankshaft position sensor as part of the swap? Also, there are differences between the manual trans, and auto trans sensor..... Think the manual trans sensor is shorter.....

 

no i did not remove or replace the sensor i was able to fit the automatic one with the flywheel but i did hit it pretty hard and it was alittle close to the flywheel so it could be it
