OK, forgive me for I am a vehicle retard...

I just got my tuner today from Doug and was reading the instructions. THe first step is to remove the fuses for the "electric fan, and fuel pump." So being the newB that I am, I went to the fuse box on the passengers side of the truck hoping that the fuses I needed to pull would be obvious. As you all prbably know, they were not obvious. So I checked my owners manual, and found the fuse diagram, but neither of the two mentioned items were listed on the fuse chart.

So I have two questions:

1. Is it important that I pull those fuses? or does it not really matter?

2. If it is important, how do I know which fuses to pull?

OK, one more thing. Do I even have and electric fan? I thought installing an electric fan was a mod I could do to improve performance and mileage...Hmmm...I told you I was a newB.

Thanks guys.

 

Go to the power distribution box under the hood on the driver's side. The fuel pump is #23. I found a reference to auxillary cooling fan which is #17. I don't have an electric fan, maybe it was an option. Check your owners manual to see the exact spot each fuse is located at. This information is for a 2001. If you don't have the manual you can download a pdf version. I got mine from the Ford owners site.

 

I checked my owners manual, but the only diagram I could find is for the fuse box on the passengers side.

 

It is a 20 amp mini fuse between #22 which is not used and #24 which is a 30 amp. (this is for the fuel pump) you already said you don't have an electric fan. #24 will be the closest to the engine and closest to the firewall of the mini fuses. #23 is still closest to the engine but 1 up toward front of truck.

Does that make sense?

 

oh, and the Owners Manual on Mazda's web site downloads with a ton of errors...Just my luck

 

Hopefully someone else will chime in. I know our trucks are alike, but I doubt the fuse boxes are. Good luck, I'm off to bed...got to get up early.

I'll check this thread again tomorrow.

 

Yeah, I am not near the truck, but I think with that info, I should be able to figure it out. #23 is the fuse to pull. Cool. I would still be interested to find out if this is a necessary precaution.

 

I have never pulled either fuse, well the one fuse as I have an electric fan but its not running when I program only the fuel pump. No problems yet, I have done it more then 6 or so times.

 

That is what I figured. Can anyone wager a guess as to why pulling just those fuses would be necessary, as opposed to any of the other fuses?

 

You don't need to pull the fuse for the fuel pump. It doesn't take more than a minute to load a program, and in that amount of time there is no worries.. With other cars, like SVT Focus's it takes like, 15 minutes... in that case you need to pull the fuse...

 

What could the program do to the fuel pump in 15 minutes that it couldn't do in 1? Or more specifically, what does the fuel pump fuse have to do withthe program.

 

not so much the fuel pump as the electrical system...i.e. the battery

 

CORRECT. Go turn on your truck, just to RUN without starting it and let the fuel pump run for 15 minutes, then try to start it...

 

How in the world do you let your truck "run" without starting it, and how in the hell do you run the fuel pump, or know if its running for that matter?

 

when you put your key in turn it to the first click thats run if you keeo going thats start when you let go of start it goes back to run so to get to run turn your key one click towerds the engin

its dosn't have to be runing for your key to be in the run postion

 

Oh, thanks.

 

He was referring to the RUN position of the ignition switch, you can clearly hear the fuel pump running in the tank and you wanted to you could just jumper the fuel pump relay. When the programmer is installed it turns the fuel pump on for some reason, must be some sort of logic in the PCM.

 

i want to get a bama tuner... what do they cost anyway?

 

couple hunskies and your first born

 

The programmer doesn't turn on the fuel pump... The programmer tells you to turn the key to "run" position, then it uploads the program. Anytime the key is set to "run" the fuel pump is ON...

 

The pump does not run the whole time the key is on with the engine off, it comes on for a few seconds and then turns off. You can hear the pump stop when the programming is complete. The programmer may not be doing it but the process of programming may be.

 

Mine will pump constantly the whole time, regardless...

 

That does not seem right, it should shut off after a few seconds after key on until you start the engine.

 

Well no electric fan but I have done it with both the fuse in and pulled. I haven't noticed a diffrence.

 

i paid 399 from kris over at Jusnes...that's about the best deal you can get for one..

i personally wouldn't care if they were chaging 500 for it...i'd still buy it...
