GT40 Reading fault codes

[macey]

Hello everyone,

Can anyone explain the procedure for reading stored fault codes on the GT40 with an Innova 3145 code reader. The instructions suggest pressing brake pedal etc.
Many thanks in advance.

What issue are you trying to resolve?

Hi, I am trying to resolve a long running issue with my engine running for a while then hunting and stalling. I have actually found a kink in the braided fuel pipe between the low pressure pump and the FCC but purchased the code reader in the meantime and just interested to see if it gives any information.

I have a 3140 and it's pretty much straight forward never used the manual.
Select obd1 and it should read the codes.
You can also do some testing first engine off key on and engine on key on.

Hunting idle can be a fuel pressure issue the tester will most likely not help, get a fuel pressure tester. I use a cheap harbor freight one the pressure values are in the pro boss manual If you don't have one let me know and I post a link.
