Anybody want to have a crack at this?

Changed plugs, rotor button, distributor cap, crank angle sensor, coil, fuel pump, and fuel pump relay. Each time car has run for a day then stops again. I suspect the real problem is the computer and or the voltage regulator. Can anyone tell me where the voltage regulator is
hiding, the alternator is not a module type. Is that the real thing?

I have blown out all the electrical connectors with compressed air, there is fuel getting through the return pipe under pressure. Again the vehicle runs beautifully when it runs, but something is kicking out the relay under the glovebox.

Is there a starter relay somewhere that I may have missed or am I really looking at the computer? I am losing the battle here and could use some help if anybody wants to have a crack at it? I have also reseated any body earth I could find.
Thanks Dave

Ok so the auto electrician decides not to read the codes, and was rather unco-operative when I told him all I wanted was to read the codes and fix it myself.
The fuel pump, crank angle sensor, and various other electrical stuff in the EFI has all been replaced now. Total $600.
The car was still starting then without warning it would stop and wouldn't start again for a while.
Finally I bit the bullet and pulled the ecu out of the car opened it up and hiding in there was a scorch mark on the motherboard. Needless to say it was then off to get a new computer.

$220 later S/H computer fitted and now she purrs, have just done 1200klms and no problemo.
Who knows how much I would have been up for if I had the lecko do it.

If ya get random readings when testing electricals, check the ECU, look for the burns on an otherwise clean board and ya might just find it. Interstingly my LHF power window switch
and air con relay are burned out too... Good luck

$220 for a secondhand computer ain't too bad, the auto electrician would have tried to get hold of a brand new one, or maybe a second hand one and do a dodgy one on ya, I would say they'd would charge at least $700.

Hey Guys,

I am an auto electrician and with that model magna, the computer is a common problem.

normally the little microchip develops a little lump and fries, othertimes u will see a leaking capacitor etc...

We normally get an Exchange Computer. this is by far a better option than getting one second hand, as u dont know when it will **** itself.

if anyone ever has dramas email me chrisyoung_18@hotmail.com

my workshop is in Hornsby, and we will certainly look after anyone.

What he said, change over ECU is the best way to go, when i thought my ECU had gone (which it nearly did but its handy having a dad who's an electronics technician, had a leaky capacitor but it hadn't done any damage yet, fixed that up nicely in time, ANYWAY) i got quoted $150 for a change over one.
