As topic title really. Been having intermittent issues with starting for a month or so now, got the cause down to shagged fuel pump. Fitted a new walbro unit and all was good, started first turn of the key. The other night I was driving and I suddenly lost all power, this was due to the distributer working its way loose as my friend didnt tighten it fully when i had it off to check it on his car to see if his one was knackered. This morning went to start the car, fired up first time, drove 5 ft then car died, felt like when you run out of petrol but the car has fuel and is getting fuel to the rail as I took the fuel line off and fuel comes out when you crank the car. I took the spark plugs out one by one and tested in the HT lead, all seem to be getting a spark although it seems weak (spark was orange/yellow, been told it should be blue/white for strong spark), the spark plugs were black and soaked in fuel. Is there an easy way to check the EFI fuse without just fitting a new one? Anything else that could be the problem, I am really stumped with this. Cheers
