#1 Electrical fault - S1 doesn't even try to start
Posted: Tue May 07, 2024 7:59 pm
After my 3.8 has been laid up for 10 months while I tackled other jobs, it now has an electrical fault it didn't before.
When I inserted the electrical cutoff switch and turned it, the low fuel light came on (it only has a gallon in there). But bear in mind the key wasn't in the ignition yet. When I inserted and turned the key, the submerged fuel pump (solid state) whirred busily then stopped, presumably when up to the 2psi I set on a new inline pressure regulator from Demon Tweaks, mounted in the pipe run between fuel tank and rear bulkhead banjo. Meanwhile, it filled the fuel filter bowl in the engine bay. When I thumbed the starter button, nothing, not even the click of the starter solenoid, never mind any attempt to turn the engine. I've tried running a separate earth to the engine in case it's developed a poor earth strap contact, though with the amount of oil coating the earth strap I'd be surprised if oxidation were possible.
In case you're wondering what might have been disturbed during the other jobs mentioned earlier, they comprised removing the camshafts to reset the valve clearances, removing the carbs to replace the jet diaphragms and changing the dynamo/water pump drive belt.
Anyone recognise the symptoms?
