A miracle....Slowy's cobra update

Guys

Am trying to source a fuel pressure gauge to test supply pressure and eliminate this off the list.

Am contemplating having my sparky back just to work through the various plugs to confirm all the sensors are at least operating as they should.

At least No. 1 plug has been out on a few occassions but also removed passenger bank over the weekend. Plenty of fuel smell but also quite sooted from burn off of the residual oil I had been squirting into the bores over time.

The injectors have remained installed so any blockage shouldn't be major but again checking and cleaning these wouldn't be a bad idea anyway. They are the original standard items from this motor.

Got bugga all time on the car yesterday after wasting Saturday trying to get it started so I've only removed various plates I needed to paint to allow me to do final install of these once dry.

Paul I had the sparky install the standard interegation plug from the falcon so with the right gear I can simply plug into the system to check it out. Never having seen it done how do the scanners plug in and work?

If I need to download to a laptop, I'm still stuck as this work machine is too heavily protected normally to let me download stray apps. without IT support and agreeance.

How do others intergogate the system?

Cheers

The cheap $20 "ELM327" OBDII clones (see below) seem to work OK on the late model GM and VW engines in my cars.

You plug the adapter into your ODBII port and it talks via USB or bluetooth to the computer or mobile phone where you have installed the application.

If you have an Android phone grab the "Torque" app from the store (it's free) and you can borrow my bluetooth adapter. That should show you any generic fault codes but you may need to buy a more expensive hand held scanner to see manufacturer-specific codes.

If nothing else this will tell you whether your ECU is actually working. My car didn't start the first time due to voltage drop across the ignition barrel - not enough juice for the ECU. Fixed it with a new ignition barrel and dedicated relay just to be safe!
