The relay is triggered from a signal coming out of the igniter.
Fuel pump power comes into the relay from the ignition switch and the igniter operates the relay.
Verify that you have power coming in on the bk/w wire. When you crank the motor, power should exit on the bk/bl to the fuel pump. If you have 12 volt power coming in and you have a new relay, then you will have to check the wire from the igniter. Also check to make sure you have spark at the plugs.
That is the relay test information.
The signal from the igniter also goes to the #1 coil. Check for spark on that plug to make sure the coil isn't bad.
Let me know what you find.
Have power coming in on the bk/w wire, but no power going out on bk/bl wire when cranking
I have not replaced the fuel relay
Only checked it to make sure I had two hot and one gound
Check for a pulse signal on the wire from the igniter and do the relay tests. Either the relay is bad or it's an ignition problem.
I have pulse signal on the igniter wire and spark to #1 plug
That's good. The problem should be in the relay then. If you have an ohm meter, check the relay. That should be the faulty part.
ok Thanks. Don't have an ohm meter. I'll order the relay and see if that takes care of it
Let me know if you need more help.
will do. Thanks
