Help ASAP Fuel Pump Constant Prime Fan Always on! Hissin?

Adam95GT · Aug 21, 2010

Someone point me in the right direction... this is how my day ended... i switched back to the stock maf and uploaded the cobra tune and the car idled for a while i cut it off and when i went and turned the key to the on position the fuel pump primed.... didnt stop priming and i noticed the fan was on...

Hissin im sure you know what pins and wires to check. I probably messed something up when i extended/ hid wires... but it wasnt doing this before.

gonna work on it tomorrow am

You have a TwEECer, right? Make sure that you have the right strategy selected (CBAZA) after uploading the tune. Also make sure that it's fully seated on the J3 port on your computer. Aside from that, I'm sure JT will be along shortly, but this should get you started anyway.

Sounds like a corrupt tune. Try reloading the tune

Its a moates QH

I tryed reloading a different tune same thing...

I started with the stock cobra tune (J4J1)... jumped to the dirtydirty cobra tune... thats after trying to start 2 times it started and idled for a bit.. then i cut it off and the problem started next start up... i tried to go back to the stock cobra tune and same thing...

I also have to find out how to change what tune im writing to the QH... its always saying writing tune 5. And i dont know exactly what its reading... i probably should read the starting guide but dont have MS word on this comp and my install disk is at my house 2hours away (just reformatted)

I just think its wiring related because the whole car has been torn apart.

Can you unplug the tuner from the J3 and try letting it prime to see what happens?

Here is some info I found. This site is the best self tuning site on the net. if you can't find the info here it isn't out there.

EECTuning.org • View topic - Fan&Fuel pump run constantly with QH. What fixes this?

I remember reading more about this but couldn't find it quickly today.

Unpluged QH' keyed on fuel pump primes and cuts off like normal... cleaned contacts and reinstalled QH same thing... Going to resend tune to qh

Adam95GT · Aug 22, 2010

No change. I deleted everything on the QH it had a bunch of AL9 files on it. i uploaded

T4MO

J4J1

Dirty Dirty J4J1

And a custom tune i made...

Still doing the same things.... fan on... pump continues to prime...

The QH and TwEECer both will do this if you don't have a tune written to them before you connect them to the EEC. Basically they are serving up static or garbage as data to the EEC without a tune.

Also try loading the same tune to all positions.

I use twEECer so I don't know anything about QH. Are you using the QH software or Binary Editor?

Thanks but again no dice... i cleaned the contacts again... sanded them and wiped them down... still the same thing... even made sure a tune was loaded before connecting...

Im using binary editor

When i turn the QH to mode 0 in BE (Factory tune) it acts normal.

I changed it back to mode 2 and the dirty dirty j4j1 tune and its working normally but i still cant get the dashboard to work.... so i dont know

Adam95GT · Aug 22, 2010

Same problem came back....

I had it running though....

usually the fan / pump constantly running thing means the computer does not like the tune that is loaded on it.

i use tweecer and it has a setting that tells it what strategy it is working with. i can't tell you what to do with QH, but i bet QH has something similar. go to eectuning.org, that is a great resource for self tuners

Adam95GT · Aug 25, 2010

Talked to craig at moates today. He took control of the laptop and noticed that im using the 1.4 version of quarter horse and i need 1.6 to use BE 2010. Im gonna send it back in to get updated Craig is the man!

That's cool, hope it gets all fixed up for you. Self tuning is a lot of fun and headaches.
