94 ram won't start after crank position sensor change
 

Hello, I recently have been working on a 94 dodge 1500 with the 5.9 in it that had pretty much every sensor changed except the one in the title. The truck still ran but once it got up to temp it would die until it cooled down again. It never over heated just dies when it got up to normal operating temp. I diagnosed it as a crank position sensor and have replaced it but now thay everything is plugged in the truck just cranks over and over again but won't start. I've also done the thermostat on it and now I'm just kind of at a loss for my it won't start. Maybe I just got a bad sensor? Or anything else I should know about? I have the weird year woth the plastic bracket and Allen head bolts and the new one seems to go down the hole farther?

Dodges hate after market sensors.

The crank sensor should be a Mopar sensor. Unfortunately, the aftermarket crank sensors tend to be hit or miss.. :icon_twocents:

Interesting, so would you recommend getting another brand? Or just getting the actual Mopar sensor? My year is the weird one with the plastic bracket and the Allen heads and I just couldnt find that one online.

I'd go for a Mopar sensor. Contact the dealer to determine if the original part number has been superseded by a newer number.

I used a Borg-Warner crank sensor in my truck several years ago. It lasted about 3 years. When it failed, the truck would randomly cut off. I'd rest the computer and it would restart. Finally, it produced a code that pointed to a bad crank sensor. Replaced it with a Mopar crank sensor as recommended by folks on this site and no more issues to-date.

Mopar Sensor. For my Jeep 5.9, It used the same crank position sensor. I got a AZ one, brought it back, 2 from NAPA brought them back. Bought a Mopar one from Ebay, worked great. I put a Mopar one in my truck too and worked.

Hey so just to test I put in the old crank sensor that it started up and ran on but this time it also was a crank no start on the original one. Should I keep looking for a mopar one or do you think its something else?

You can do this here. As you can see it's discontinued. I put in a Delphi one years ago and it's still working.

Just curious - did Delphi make the crank sensors for Dodge?

Hey so I found the Delphi branded one for my truck my concern though is that even when I put in the original one it was a crank no start where previously it ran on that one until it got up to temp so maybe another issue? I replaced all the coil wires leading to the distributor but maybe it's a distributor issue? I'm 90% sure the fuel pump is working.
