M12 GTO R will not start

[mgwanderer]

Hi there,( I am new here and would like to say hello before I start asking questions )

I am trying to find information so that I can fault find on the above car. It was driving normally before suddenly dying??

Checked alarm which appears to work (alarm on engine does not turn / alarm off engine turns , petrol pump runs, 12v on coil packs)

Tried changing crank and cam sensors still the same

ECU is MBE 975B 30L but I cannot find any info on this

Is it a serial ECU or can/bus

Which easimap software do I use 4,5,or 6

I cannot find anything on the MBE website as it appears to be too old, can anybody help or advise me where to look

Many thanks in advance

ps Car was running great before it just died, it is immaculate and has only 20,000 on the clock

Might not be the problem, but you can check the grounds.

Thanks for that, I was beginning to think I was the only one here. I will check them all and keep searching if it doesn't help

Sounds silly, but check all fuses and state of your battery

I see you checked the voltage at the coils - have you checked the voltage at the fuel injectors, the crank sensor, cam sensor, TPS, and MAP sensor? Have you checked the fuses in the four-fuse block in the engine compartment? How about the relays in the engine compartment? After running the fuel pump, do you have fuel pressure at the fuel rail? Do you have spark while cranking? Are your injectors spraying while cranking?

You can get pretty far diagnosing a no-start on these cars without hooking up a computer…

Easimap is 5.0 is the software

Does the tachometer move when you crank it over?

Check ground at the gearbox to frame, location is underneath. You should have a 6mm stud welded to the frame down by the battery in the center section that generally doesn’t have a belly pan covering it.

I have seen people ignore their fuel filters. Make sure the system is pressuring after the filter

Did you open the gas cap?

Try charging or jumping the battery

As some folks have mentioned, check the fuses in the engine bay. When i first got my car I had a problem whereby it would just switch off completely and pop one of the 4x fuses. After lots of investigation by an auto electrical friend he found some melted wires that were then rubbing on the chassis and popping the fuse

Hi again,
still no joy with starting, does any body have the 975b ecu config file (ec2) for the easy map software, I am using a 992 ec2 file at the moment but I am not sure how much of the data shown is correct?

regards

Clive

For what you’re trying to do, it might be easier to find a copy of the “Noble Dealer Diagnostic Software” - you should be able to find it out on the web. It should work right out of the box - no need to look for all the bits and pieces like you have to do with Easimap.

Anyway, for a no-start, you should be able to just treat the ECU as a black box, and go through the normal troubleshooting procedures - do you have spark and fuel? When you crank the engine over, does it sound like you have compression? On these cars, the tach and the coolant temp gauges are run off the ECU - are these working? Does the coolant temp gauge change when you disconnect the sender? Does the tach work? Is your battery fully charged? What voltage are you seeing, both with the key in the run position (and immobilizer disabled) and while cranking? What fuel pressure are you seeing at the fuel rail? What condition are your spark plugs? These are all things that I would start with before hooking up the laptop…
