ECU fuse blowing - can anyone save my 75?

Hi, I wonder if anyone has had a similar issue, or can offer any suggestions to help save my 75 (2.0 V6) from the breakers.



In short, 2 weeks ago, my 75 left broke down (failure 1) and ended up being recovered by the RAC who suggested that there was a crank sensor failure - the diags were apparently also showing errors with the VIS, lambda, and other sensors. The car was recovered to my local garage who quickly identified that the 'number 1' 15A fuse (engine bay fuse box) had blown. This was replaced, the car started, and I drove the couple of miles home. A few days later, about 6 miles into a longer journey, the car died again - the same fuse had blown (failure 2). I replaced the fuse at the roadside and drove back to the garage. Several days later (I'd been working away) the garage returned the car to me having apparently found an electrical short in the engine bay and repaired it. I was told that they had been able to replicate the fault by changing from R to D and then accelerating - every time, the fuse blew immediately. After their work, this was no longer the case and a road test had been a success.



Feeling optimistic I took the car out for a drive and suffered failure 3, 4 and 5 within the space of about 5 miles. After the final failure I noted that it had also developed a new 'feature' - when started, the engine ticked over over as normal. If the throttle was touched, the revs did not decay and would actually build to circa 3k RPM; I assumed that something had gone away with the TPS too.



The car is now back with the garage and they have not been able to diagnose the root cause of the repeated failures, or what seems to be a cascade of failures/errors/issues. Does anyone have any thoughts/ideas? I'd hate my 75 to be heading to the breakers (especially since it only has 55k on the clock, I'd just had it serviced and had the belts/tensioners were done last year too!).



Thanks in advance



1st failure
Turning right out of of a t-junction, full throttle (15A 'number 1 ECU' fuse blown)



2nd failure

Turning right out of of a t-junction, full throttle (15A 'number 1 ECU' fuse blown)



3rd failure

Went under braking - the ABS triggered on some mud and the engine went at exactly the same time. (15A 'number 1 ECU' fuse blown)



4th failure

Went under acceleration at about 2/3 throttle with at 4k RPM (15A 'number 1 ECU' fuse blown)



5th failure

Went under little/no throttle having turned off Top Toad onto Rudyard Road (20A fuse blown - I'd run out of 15A by this stage)
