Customer Question

I have a 1999 RAV4 that won't start
nothing happens when I turn the key other than the accessories coming on
I checked the fuses under the hood and the fusible links and can find nothing blown
I bypassed the clutch switch to eliminate that
The starter will crank if its jumped
Kinda stumped

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?

Customer: replied 1 year ago.
Was not jump started and the fusible links look fine
Expert:  Ted Ritter replied 1 year ago.

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.

Customer: replied 1 year ago.
I tested the starter relay with an ohm meter and it had continuity
Expert:  Ted Ritter replied 1 year ago.

Ok, is there power to the relay?

Expert:  Ted Ritter replied 1 year ago.

With the key on there are two terminals that are hot.

Customer: replied 1 year ago.
Ok I'll try that
Customer: replied 1 year ago.
No there doesn't seem to be any power there
Expert:  Ted Ritter replied 1 year ago.

Ok, check to make sure the 40A Main fuse has power to it and is not blown.

Customer: replied 1 year ago.
It's not blown but I don't seem to be getting power there either
Expert:  Ted Ritter replied 1 year ago.

OK, stand by I'm going to look at the wiring diagram

Customer: replied 1 year ago.
Ok
Expert:  Ted Ritter replied 1 year ago.

The 40A main fuse gets power directly from the fusible link block.

Customer: replied 1 year ago.
Ok I'm with you
Expert:  Ted Ritter replied 1 year ago.

Did you open the cover of the fusible link block to visually inspect the segments.

Customer: replied 1 year ago.
I didn't see anything
I took the cover off the side and where the cables attach to the block there was nothing visible
Not sure if there could be damage I between the link and the cable?
Expert:  Ted Ritter replied 1 year ago.

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.

Customer: replied 1 year ago.
12.34 volts
Expert:  Ted Ritter replied 1 year ago.

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?

Customer: replied 1 year ago.
I'll give it a try
Expert:  Ted Ritter replied 1 year ago.

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.

Customer: replied 1 year ago.
Same as before
Nothing happened
Customer: replied 1 year ago.
Hello?
Expert:  Ted Ritter replied 1 year ago.

Yes, I hac to step out for a bit, be right back.

Expert:  Ted Ritter replied 1 year ago.

On the clutch start switch did you jump between the red and black wire?

Customer: replied 1 year ago.
The switch at the clutch pedal?
Expert:  Ted Ritter replied 1 year ago.

Yes.

Customer: replied 1 year ago.
I made a jumper wire to bypass the switch
Expert:  Ted Ritter replied 1 year ago.

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?

Expert:  Ted Ritter replied 1 year ago.

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.

Customer: replied 1 year ago.
Ok I'll give it a try
Thanks for your help
Expert:  Ted Ritter replied 1 year ago.

I'm back online, let me know how it's going.

Customer: replied 1 year ago.
I tried your suggestion and I was able to turn the engine over but it wouldn't start
I talked to my brother who is a small engine tech and thinks it's the ignition switch
Expert:  Ted Ritter replied 1 year ago.

That's a possibility, was the switch in the on position?

Customer: replied 1 year ago.
Expert:  Ted Ritter replied 1 year ago.

Yes, it should have started then, the switch makes sense, try a new one and let's see what happens.

Customer: replied 1 year ago.
I'll look into that
I don't think that's something I want tackle, probably have a local shop do it
Expert:  Ted Ritter replied 1 year ago.

Ok, sounds good, hope you get it resolved by replacing it.

Customer: replied 1 year ago.
Me to
Expert:  Ted Ritter replied 1 year ago.

Good luck.
