Re: Volvo Penta does not accelerate
I saw 43GL, but that was the extent of the letters and numbers. I thought you were looking for 5 to 7 total
Now, we are getting somewhere. I was looking for 5 to 7 total, but I did want the ones that were actually there, not the 28. Where did that come from.
What you have is a 4.3GL-PLKD.
That tells me it carbed and a LK model engine.
Now, on with your problem. Since it will start, and only run for a few seconds, that tells me the relay and the pump are both working. Each time you start it, the pump and relay works to add a little fuel to the carb each time.
Remove the fuel pump relay (next to the pump) then make a jumper wire and jump between the Red/purple (30) wire and the yellow/red (87) wire on the relay socket. You should here the pump run. If you do, start the engine (Don't forget to hook up water to the drive) and see that it keeps running. If it does, while it's still running use a meter and check the voltage on the green wire on the socket (85). You should see over 12 Volts, if nothing, check the voltage on the green terminal on the alternator. If nothing, replace the alternator, if you do have over 12 volts, you need a new diode in the green wire.
