Toyota Repair Problems? Ask a Mechanic for Answers ASAP
Hello, thanks for posting
Was it jump started prior to this happening? Did you check the fusible link block attached to the positive battery terminal?
Ok, thanks for the reply, I believe there is a starter relay in the fuse box under the hood, try swapping it with one that matches up.
Ok, is there power to the relay?
With the key on there are two terminals that are hot.
Ok, check to make sure the 40A Main fuse has power to it and is not blown.
OK, stand by I'm going to look at the wiring diagram
The 40A main fuse gets power directly from the fusible link block.
Did you open the cover of the fusible link block to visually inspect the segments.
The voltage is lost between there and the 40A fuse, Do you have voltage to the 20A ignition fuse, should be hot at all times.
That's good, that fuse and the 40A fuse get power from the 80A fuse so we know it is good. Can you make a jumper from the battery directly to the 40A fuse then see if it starts?
By doing that you are putting power directly to the starter relay, when the clutch is depressed there is power put to another terminal and the relay closes causing the starter to engage. Let me know what happens.
Yes, I hac to step out for a bit, be right back.
On the clutch start switch did you jump between the red and black wire?
Ok so the problem is that the starter relay is still not getting power, with the switch jumped and the key on there has to be power to the #1 and #5 terminal of the relay, #3 goes directly to the starter and #2 is ground. When the key is turned to start the relay closes and the starter engages.
Earlier you mentioned that you jumped the starter and it was cranking the engine, how did you jump it?
I really have to leave for a couple of hours, here's what you can try doing while i"m offline.
Remove the starter relay, make a jumper directly from thre battery, briefly touch each relay terminal in the socket, one of them should turn the starter over, keep in mind one of them is ground so if you get a spark it's thre ground wire, you ccan't blow a fuse because there are none in this bypass circuit, I will check back with you.
I'm back online, let me know how it's going.
That's a possibility, was the switch in the on position?
Yes, it should have started then, the switch makes sense, try a new one and let's see what happens.
Ok, sounds good, hope you get it resolved by replacing it.
