Apex Code help

[johno]

New build 07 apex Was just starting to pull up a hill half throttle and sled stopped dead and Was flashing light and Code 20
When I look on the sheet I found on Snowest Code 20 is Intake airpressure/Atmospheric pressure and says it should still run.
When I turn on the key no fuel pump and no start. It turns over though.
Anyone have any suggestions.?

I've had this code before and need to check your sensor right on the fuel rail. Make sure there is no moisture in it. I've also had my fuel box throw this code, ended up with putting on a new box. You should be able to bypass your box to check if that is the problem. Hope this may help a little.

Also check your cdi box down by your battery, and check all your fuses...

Fuel box

Were you running a pure logic box?
Mine is dead and when I turn the key I dont get fuel pumps etc.
I will check those.
I appreciate the feedback.

CODE 20---Atmospheric pressure sensor clogged--Intake air pressure sensor hose is cloged,kinked
Malfunction of atmo press sensor
Ecu malfunction

Atmospheric pressure sensor flat 3 conector wires pink Black and blue voltage 4.75-5.25. or intake air pressure sensor.
But most likley you have a a conection problem with hose or elec issue

Found dead fuse

Found a dead 10 amp fuse on the block by the battery and replaced and got the sled to start without the intercooler.
Still showing a code 20 and flashing
Lord is this the sensor on the top of the fuel rail that I tied my pure logic box into?
Where does it get its reading and I can trace it and see if it is a plugged hose etc.
I appreciate the help and replies.

code 20

The sensor has a small black vacuum line connecting to it on the bottomside. if you take the two bolts out you can move the sensor and see the sensing line. With my PL box If I get a code 20, I have to connect that sensor up stock, start the sled, clear the code and then re-solder the PL box into that line. PITA to say the least. The other sensor that can give the code 20 is up in the front of the sled right by the cdi. It has no sensing line just the sensor and wiring for it. Hope this helps.

Like the other guys said check for kinked lines, corrotion on any connectors. My code 20 I found I had moisture in my box, and throwing codes all over. Go into the diagnostics on your sled and try erase the code, if you haven't done that I can help with that. PM me and we can go from there. I know how ya feel when these fricken codes don't go away.

I really appreciate it.

It now appears I was supposed to up the amperage of the fuse down there so I can run the auxillary fuel pump and various guages.
Does anyone know if tripping that fuse sent the code as the pure logic box is in line on that sensor and the power to it was interrupted.
Best guess so far is that overloaded the fuse caused it to trip and kill both the fuel pumps and the box and this is why it showed the code.
If there is a way I can reset the sensor code without unplugging and then rewiring the box?
I appreciate it guys.

resetting codes

Anyone have the procedure for resetting codes and going into diag mode?
I searched but the old site is down and didnt get any good results.
I appreciate it.
