I just put in a b18a in my 90 hatch si and I can't get the damn thing started it turn and everything sounds like its about to catch on but no luck. I checked my grounds, all the fuses, switched out the main relay still the same thing. I pulled off the fuel line going to the fuel filter and turned it on no fuel. So I checked the fuses again all good. I pulled the back seat off and checked the wire going to the gas tank. I metered the wires and this is what I got, the yellow/white wire I got 5.8 volts when turned to ignition, black/white tested ground, black with two gray dots tested ground, yellow/black with two gray dots tested ground when ignition on and nothing when ignition off. But when I plugged the harness back the section that goes into the tank all the wires still checks out the same except for the yellow/white the voltage drop from 5.8v to .80v. What do you guys think do I have a bad fuel pump or something went wrong with the electrical. Thanks.

 

Just run power to the fuel pump for a second to see if it is working or not. If it does than your problem is electrical. If not than the pump if dead.

 

when you turn the key to aux. power do you hear it prime?

 

So just run a 12volt wire to the yellow/white and listen for the pump. Damn it!! Why didn't I think of that this morning.

Nope I did not hear it prime at all. At first I thought it was the pump cause I didn't here it prime but I decided to check everything possible first cause a buddy of mine says that I have to take down the gas tank to change the pump. Thats when I found that the yellow/white wire only put out 5.8volts. Don't most of the components in the car take 12v DC?
