I try to do a crank relearn and it doesn't work

[CRU SS N]

When I bring up the relearn screen and hit start. I raise the rpm up, but the rpm climbs all the way up to redline (7000 rpm) and doesn't stop at 5000 like the directions say it will. I've tried it several times and it hasn't worked. Any suggetsions would be great. Thanks, Brian

How fast are you bringing the RPM's up? You need to do it in a fairly quick manner.

I was trying to spread the rpm rise over the 10 seconds so maybe that is my problem. I thaught I tried it fast once, but I may not have. I'll try that when I go home for lunch today. Thanks

Here is the P1336 it mentions http://www.ls2.com/boggs/dtcs/DTC%20P1336.htm

I think it does have that code stored. I tried to reset the codes and do it again, but the code comes back as soon as I turn the car on again after I reset the code. I know the code that comes up for the crank not being learned is not on the list of unacceptable codes in EFILive for the crank relearn. Thanks a lot, Brian

I guess my next question is how do I reset that code so that I can perform the relearn before the code comes back. Thanks, Brian

Here's an interesting one -- I'm having trouble getting the crank relearn to work on my 1998 Formula, because whenever I rev the throttle it picks up a false VSS signal!! If I keep blipping the throttle in neutral, I can get the car "moving" 30 MPH ... The car has ALWAYS done that, even when it was bone stock.

I'm having the same problem on my new LS1 engine....arrgghhh.

I haven't done one in a while, but as a I recall, the PCM only shuts off the injectors for a split second. It will feel like a stumble and that's when you need to let off.
