![]() Now check between engine block and battery negative terminal. There should be very little voltage drop here, under 0.1 volt. Have your helper crank again for 5 seconds. Again dig in the points of the probes to get a good connection. Next connect one meter lead to the starter housing, and the other to the engine block. You should see under 1 volt, preferably under 0.5 volt. Now have your helper crank the engine for 5 seconds and watch the multimeter reading. Use the points of the probes to dig in through any dirt or corrosion to get a solid connection. Attach the other meter lead to the starter positive terminal post. Attach one meter lead to the battery positive terminal. Now the engine will crank without starting but without dumping in raw fuel. Pull the fuel pump fuse while engine is idling to bleed off the fuel rail pressure. ![]() You will need a helper and a digital multimeter for this.
