What does this mean?

I plugged in a predator today to correct my speedo issue and while I was in there I checked my trouble codes. I had a bunch for the auto trans I don't have and then I had:

P1237 fuel pump secondary circuit(fuel pump driver module)

What does this mean?

Is this the first time you've read the codes? How many miles, etc? I would clear the codes and drive it and see what happens.

Yes it is and it has a little over 90k on it- I cleared the codes and started the car, but it came back...

Another thing I noticed...when I turn the key to run the fuel pump runs continuously. Shouldn't it just prime and then shut off until started? Could my fpdm be giving me a Cleveland steamer?

Any ideas?? I'm gonna pull the connector off the fpdm tomorrow and clean it up some/look for broken or worn wires.

Sounds like the FPDM might be bad. You can usually get them used really cheap. Like $20-30.

I'm right about the fuel pump though right? It should just prime for a second or two with the key in run and then shut off until you start it right? Also the predator says my fuel pressure is 90psi at idle...shouldn't it be around 40?

Where is the fpdm located?

stal94gt · January 15th, 2012, 10:48 PM

Your tune is incorrect if your getting codes for an auto. You need to get a new tune to get rid of the codes. Also the fpdm is on the driver side rear fender behind the liner in the trunk

Yea I know that, I just picked the car up knowing it was swapped and not tuned because the speedo was reading double. My buddy had a predator laying around so i figured I'd use that to correct the speedo. I expected to see the codes for the auto, but the fpdm caught me off guard...
