(450 amps could be wrong, when i tested mine it read 212 amps and it was nowhere near good, soo maybe anything higher then 300?)


idk like i said just have pep boys test it.. if its bad then its the battery,
get a new one and if it still doesnt start the car its the big wire going to the starter.. replace that and should be running!


We need to figure out if he is getting voltage before we try checking for amps.... mv is a way of checking for small voltage. And he said in the OP that he put a new battery in it.

And Congo u still haven answered three very important questions for any one tohelp u trobleshoot this problem. Let's focus on one problem at a time so we stay on track with the title of the post. The three questions are .....

the voltage reading on big cable.


Voltage on small wire goin to starter when key is being turned..

And is the main ground cable hooked up to the block.

I know u gave me A reading but didn't specify if it was the big or small wire.

just replace the hoses there is no permanent way of repairing it without getting new hoses..but this is off topic..

the reading off the big cable going to the starter? we need to know that
do you have a brand new battery? or like acouple months?

Conga1991 09-18-2010 11:18 PM

I did get a brand new battery, the reading is from the big wire coming from the battery. and yes I grounded it to the block but when i put the positive on the post it the wire I grounded to the block sparked both ends and melted some of the ground wire that was on the negative post.

It shouldn't do that...... so what I think is goin on is that washer that is on the starter caused the big or main cable to ground out on the starter its self. The 400mv u are getting is from a ground loop or otherwise known as ghost voltage so it has an open in the line. probably the fuse but possible ly the cable itself. So get a new fuse and get u a washer u can make one pretty easy out of any plastic but is try to go Atleast 1/16" make sure your connections are good and id check the ground wire for continuity to make sure it didn't break from bein shorted. Unlikey cuz the fuse is a lot weaker then the wire.. and this is assuming u had a good ground when tested the big wire.

Another way to check this is run a new cable straight from the battery to the starter and see if it fires.. with a new washer of course or you will have fireworks

So I went to schucks to check if the starter is still good, its bad, didnt do anything. there was still enough plastic so the nut wouldnt touch the starter. So im buying a new one fom them for 70$, is that good for a brand new one? toyota parts store isnt open to call and get a quote.

Travis89Turbo 09-19-2010 11:41 PM

Ya that's a good price. I think Toyota. Is like 200

Conga1991 09-26-2010 01:53 AM

So I put the starter on and replaced the battery cables, still didnt turn over. I'm starting to get frustrated with this damn thing! I checked all my ground wires and they are all bolted on tight.

I dont know what else the problem could be besides the ignition wiring, how can I check to see if the problem is that or if its the clutch safety switch?

Travis89Turbo 09-26-2010 02:15 AM

U check it for continuity between both terminals.

I don't think that is your problem though.. the problem lies on whatever wire u checked that had 400mv. If thats the big cable check the fusible link about six inches back from the starter.

If its the little wire then Chase it back all the way to the ignition connection.

ochowdero 09-26-2010 02:21 AM

haha i gotta ask this...

cars manual right?
i gotta ask the dumbest question before asking another..

your stepping on the clutch when you start the car right? lol
i gotta know

on the other hand...
do what travis said...check the continuity in both wires... if you replaced them..then check the volts on em..
search to find the "GOOD VOLT" numbers cuz i dont remember...
if its the big one..make sure its grounded correctly... the lil one follow it to the ignition wiring...could be connected wrong..
;)
make sure you step on the clutch! hahaha

Conga1991 09-26-2010 02:26 AM

I did step on the clutch. Also what do you mean by grounded correctly?? the ground wire that goes all the way to the block and on the side of the bay then Yes. Also I replaced the positive battery cable not the negative.

For the ignition wiring, where do I start to check the continuity? the plug that goes into the starter?
