1/ Is there good supply volts to the ECU while it's cranking ?
2/ I guess it definately has a 60-2 volvo flywheel and not something daft like a 16v 44 tooth flywheel or sommat ? I only ask because one kid who couldn't get his to start had done exactly that !!
3/ There is a slight difference in early and late looms in terms of power supply to the ignition module. One uses 2 pins and one uses just the one. Sometimes you have to bridge the pins in the connector, or inside the module so you can use an old loom with a new module, or vice versa, which ever it was.
I think I uploaded the old and the new wiring diagrams in to the files section. Search for volvo, or they're in my folder I think.
