Hello folks, I have a 7FGU30 that's been giving me fits. Let me try and explain the behavior and some of the steps already taken.
No crank
No start
Checked all grounds, all fuses, all relays. All test fine.
When starter relay contact terminals are jumpered, it will crank but will not fire. Tested voltage at starter relay coil terminals and not getting ground to the ground terminal of the relay coil when start switch cranked. The strange part is when trying to crank, I actually get a positive 12vdc to both coil terminals of that relay but no ground. Checked for broken or damaged wires but did not find any.
Regulator solenoid seems to be getting power as I can hear it click when trying to crank. When spraying starter fluid into the air box and jumpering the starter relay contacts, it cranks and sounds like it wants to start but never does. So I'm at least getting spark.
Both the no crank and no start issues happened at the same time so I feel they are likely related. I may be way off here but I am suspecting possibly an ECU issue. There is an ECU underneath the left foot step with a part number of 24610-U2201-71 that a mechanic friend suggested to swap out and try but I really don't know what this ECU is responsible for and I would rather just not throw parts at it without being fairly confident that this is the issue.
I would really appreciate some guidance with this. I'm just at a point where I feel totally defeated.

Follow your ground cable from battery to frame and check make sure you have good ground to engine from battery if it isn't grounded well it will have same problem as a weak battery
Hi John, yes there is a switch that prevents it from cranking when the gear selector is in forward or reverse but I believe it is working because when I put the gear selector in either forward or reverse and try cranking, nothing at all comes alive. But when I put it in neutral and try cranking, I hear a rapid clicking sound coming from something in the engine. It almost sounds like the sound a starter makes when the battery is weak but I'm 100% sure it's not coming from the starter. Not sure where it's coming from. But I will take a closer look and try to identify the switch you are referring to.
I remember there should be a switch on the gearbox that prefends starting when in forward or backward.
Try to make a little bridge over that sensor and see if it cranks.
John
