I'm currenty in the process if getting my car tuned & I get two codes thrown. I need some help here. I have a duel SVT Focus pump, but not the one with the part # 3S4Z-9H307-BC. There has been another brand new one released & right now at 2am I do not have the part # handy. As it is I have this pump & the two codes that came up are P1235 - Fuel pump out of range voltage, & P1237 Fuel pump too high voltage. I need help on suggestions of what to do! I was told that I have a small black box; the fuel command module in the back of the car that 'may' have been fried tonight also, so I am needing so help here. What do I do? How can I fix these codes?

 

Sorry, kinda OT, but what is an SVT Focus pump? I'm assuming its a type of aftermarket fuel pump, but what benefits does it carry?

 

dude, what happened with the car are you just adding the dual pump??? how and what would have fried your fuel management. what exactly happened? have you tried running the stock pump?


oh and the svt focus as in car is where the pump is from

 

It's a the SVT's Focus's fuel pump. It's a duel intank pump that can pump out substantially more gph than any other intank pump. It's something like 100gph vs a Holley's 60 approx. I don't know all the specific details off the top of my head. I have them written down somewhere.

 

No, I'm not just adding a pump. I have as many mods as Code3 does. Apparently what happened is that when the car was strapped on the dyno the codes came up shortly after trying to get some new baselines. After which time the car would die, and wouldn't even prime when they tried it again (you know when you turn the ignition and you hear the injectors...). It cranks, but just won't turn over. I guess my fuel command module is toast now, so I am getting another one TODAY if possible. I need to know if maybe during the install of the pump that somehow the f.c.m. short circuited, or if I can get some other f.c.m that can withstand the voltage from this new pump. I just want my F**ckin car back already!!!!!!!!

 

I had the same thing happen, had to replace the module. Hey GSXR remember when I told ya about being prepared for the lil stuff like sensors and such???? Keep your chin up, Bro...s'all good.

 

I already had them replace the factory camshaft sensor just in case. I was wondering though, if the factory sensor will be good enough. After all, I have some pretty aggressive cams & am curious if they stock sensor is good enough for them.

 

When you installed the new one did everything work out? I have a direct replacement for my f.c.m. I don't know if there are other kinds, or what will prevent this bullsh*t from happening again. What will be the difference from the current toasted one vs the new one I just bought? Did you go with some other type of f.c.m? Did if fry due to extremely high amount of amps put out by the new pump? I think our cars are like 12volts, but I am not sure about this focus pump.

 

Any other surprises that I need to be warned about?

 

Is anyone going to chime in here or what?!
