Hello everyone,

Could anybody tell me where the crank sensor is located for my 95 GS300? Or if even this car has one? I remember someone telling me that this car reads the ignition signal straight off the distributor. This is a car I bought from the UK.

Long story short, this car cranks but doesn't start. When we ran OBD code test, we got code 14 for ignition signal failure. Auto elec friend came and did his tests, and found that there's power, but no pulse. We need to check the crank sensor to eliminate the last component off the list that we haven't checked, failing that the distributor needs to be checked.

We did remove the lower cover on the front part of the engine and looked for it down by the crankshaft pulley (removed that too), but to no avail...

Thanks in advance, any help is really appreciated.

 

2jzge gets its crank signal from the distributor.

"CAMSHAFT POSITION IS DETECTED BY THE PICK–UP COIL INSTALLED INSIDE THE DISTRIBUTOR. CRANKSHAFT POSITION IS INPUT AS A CONTROL SIGNAL TO TERMINALS G1 AND G2 OF THE ENGINE CONTROL MODULE (ENGINE AND ELECTRONICALLY CONTROLLED TRANSMISSION ECU), AND ENGINE SPEED IS INPUT INTO TERMINAL NE"

 

I realize you said code 14, which is the igniter actually.

 

Thanks for the speedy reply and additonal info. Appreciated.

But we did replace both the ignition coil and the igniter (tested this same igniter with my 93 camry and it worked). With the new coil the car nearly started, the water pump even kicked in. Doesn't ignition signal failure refer to any problem anywhere in the whole ignition system?

We get no pulse at the fuel injectors or by the coil/igniter. This whole mess started after we replaced the busted radiator, and I disconnected the battery just for extra safety. The car started up perfectly before this...

Also, I've got a pic of what my distributor looks like without the cap. It's different from your diagram?

 

Did you blow a fuse disconnecting the battery perhaps? That picture came right out of the jzs147 gs300 manual so I believe its referring to under the rotor? but maybe not... I haven't worked on a distributor for many years.

 

No, we've checked everything from the fuses and relays to the ECU and wiring system itself. At this point I really can't imagine that it's anything other than the distributor.

Yes, but that's probably from a US version of the car? I've noticed that the US manuals differ in a few ways to the ones issued elsewhere, even the fuseboxes are different. That rotor from the one in the manual, I don't have that gear on mine.

I think I'll just have to save up for a new distributor, I don't think these things can be repaired. Have to replace ageing components anyway.

 

My apologies, yes that is from a USA car; although you're picture looks rather familiar with the rotor in comparison to the manual with the cog wheel.

Yes, i do remember when I first bought my car used I had similar issues; found a replacement distributor for cheap on ebay and that solved my issues with lack of starting, so i believe that could be a problem in yours if the igniter and wiring are looking fine.

Also i never knew the fuse boxes were different. Can I see some pictures of your engine bay?

 

Sure no problem, although much of it is disassembled in the front area. I'll also take two inner lid photos of both fuse boxes tomorrow so you can see.

 

Here they are.

 

Very similar for the engine compartment. One main thing I notice is your headlight fuses are 15A while mine is 10A, but extremely similar. The under dash fuse box you posted second is widely different in orientation to ours but mostly has the same things aside from TV or TEMS. Cool stuff! Yours having the japanese labels there makes me think your car is more true to the japanese sold cars than the north america destined version which seems most all in english.

 

Most likely yes. I was also told in an older post (in relation to my non start issues) about something called a "DOME" fuse/relay? I don't seem to have one of those. My odometer also has a function to switch between the metric and imperial systems, (I use metric) but I haven't figured out how to configure it yet.

The engine bay is mostly the same I'd imagine. When the car is reassembled I'll post a pic of that too.

 

your 10A Dome is shown at the top right of the engine bay fuse block that you posted. I believe this is tied in with the security system. In both cases of my car not starting, not locking doors/rolling windows down, one time was this dome fuse, and the other time was corroded battery terminals.

 

Totally missed that, my bad... Luckily all the fuses in both boxes are good.
