That is a crying shame... a real opportunity missed.... that saddens me. We are extreemely close, in my oponion, to finding a fix for this common 610 fault of cutting out. With the tests that Mr MVS and Mr Dini have done, a real solution could well have been found.
This fault appears to be heat related and with that in mind and a bit of lateral thinking, I looked at the fuel pump workings of the GTA turbo, and found that the priming and running of the fuel pumps.... (yes, plural, they are wired in parallel and thus run together even when priming).... are driven by pin 6 of the ECU. So my thinking is.... if you have a GTA Turbo and you have intermittent cutting out..... try the earth strap. However, one word of warning, you will need to identify the fuel pump relay by the ECU.... it is positioned below the ECU on the RHS..... and you will need to identify which pin goes from the relay to pin 6 of the ECU. On the '86 model year it is an Orange wire, and on the '87, '88, '89 and '90 model years, it is Brown.... Make sure model year is checked.
To me there is a possibility that somewhere along the curcuit from pin 6 of the ECU to the processor via the transistor and diode, and, of course the earth link from the transistor to earth, there is a crack in the print, a lead through, or a cracked/dry joint on the legs of the pins of the components, that opens up with the unit warming up, which.... possibly.... does not open up in the GTA,s case when the ECU is stood off from the bulkhead. Its just an idea at the moment, but worth considering should a GTA turbo have this fault.
I await being shot down in falmes.

Why would they do that ?? ......
Yes Lee, I have found that as well...... god knows why it is different.
