Another white Maestro owner here, I’ve had this one for about 7 years, sadly no digital dash in this one.

Good to hear it is running better with the fuel tank clean, shame about the head gasket 😬. I had the same issues related to the relays on mine (funnily enough)after I got it running, on mine it would not start one day, no 12 volt feed to the injectors, found the grey relay above the gearbox/ on the inner wing was faulty, replaced it, had been fine every since. From memory there are a couple of grey relays, I cross referenced them and got them from Ecp and replaced both, hopefully that’s all you need on yours.

The next problem you will have if this has cured the fault, is getting a tank, don’t think they are available new, I had mine removed, split treated for the rust and rebuilt, obviously not every where will offer this service. Another option would be to get a race/ rally fuel tank that fits in the boot as a temporary option and rig that up.

That’s good news, hopefully you can rig it up and give it a good run to confirm 100%, I’ve taken mine out for a run today

Hi Grogee, I had the same problem with my 1988 mg maestro after being sat up for 10 years, the fuel tank was full of rust, would run fine for a couple of miles, start misfiring cutting out, leave it for a while would start up, sometimes would run ok ish.I know you did the test measuring the quantity opening the injectors and measuring the fuel that came out, but this wouldn’t prove the fault as the slit/ rust in the tank will take a while to block the gauze. The best way to prove this without removing the tank would be to get a 5 litre fuel can (drill a hole in the cap just big enough to squeeze the 8mm hose in)and a long length of fuel hose and run the car off that, would be fairly easy to set up with the fuel pump being external. I could be totally wrong but I would advise you to consider this (I had the same problem with the shims as you, if my memory is correct I used a cavalier 1.7td shim tool to do mine without removing the cam.
