Question: Problem w/fuel pressure

[CBJ61NASH]

Hopefully someone has an answer for this problem I had the other night. I went to pull my truck at the local county fair and had a hell of a run going, probably a winning run, when my truck shut down on me. I got it restarted shortly after that and had a check engine light that appeared on the dash. The light was for to high of rail pressure, this has never happened before and I am running the same programming and set up that I have pulled with all season. I do have dual cp3's but I have probably 10 passes on them with no previous problems. Anyway, does anyone have an idea why it would of overfueled? Thanks for any help. Josh

It didnt over fuel it over pressured

I would check C1801 C1807 to C1810

you probably had a spike that set the code

It did spike, I just dont know why. Is it normal for that to happen? Is there anything I can do to keep it from doing this again? I dont know enough about efi live to know how to adjust for it. Thanks for any help. Josh

Not much you can do about a spike....atleast that i know of?
with EFI you can stop the code....and perhaps smooth your tune but I would just change the code and lever B
