Jumper cables hooked up backwards.....

I left my lights on and the drained the battery in my 93 TT. The security guard from my office decided to help the situation by jumping the car off with the cables reversed on my Supra. I have replaced the obviously blown fuses, but am stuck with a TT that wont even try to crank. Any guesses...

 

Thanks

Has anyone got a pic of the fuse box ? ive searched but cant find one, when this happened to my car it blew the 120 amp fuse with the clear cover over it so its not that obvious to spot.

 

If your stood in front of the car its to the left front corner of the fuse box, to remove it you need to unbolt it from the underneath of the fusebox , it isnt one of the push in ones !!

I called myself checking the 120A alternator fuse through the clear top, but I may check it for continuity when I get home. Basically, all of the electronics are working, but when I turn the key ....silence. Would hooking up a code reader do any good since the car wont actually crank?

 

Thx guys!

sorry misread, if it cranks and you get nothing working after something like this, in my case its always been the ignitor pack..

 

 

so your car is not even cranking..

 

do you have an immob ?

 

maybe the inline fuse has blown to it ?

 

or maybe a fuse main ones..

 

if its a manual try and bump start it, to rule out starter

 

i would still try the ignitor pack

Hey Guys...finally got the 120 amp replaced and the car will now turn over but not crank. Can someone describe to me where I would find the ignitior pack.

 

Thx....Rosie

I still feel that your problem will be alarm or fuse related. first check to see that you have a 12v feed to the coilpack connector (black wire+orange tracer) with the ignition on if you do, then you can carry on doing your ignitor pack ecu checks, if you do not have any ignition feed then the problem is pre-ecu (fuses/alarm)

If the dash is lighting up then surely the immobilisor part of the alarm is working? Wouldn't running a diagnostic check confirm or deny this?

It all depends on what alarm the vehicle has fitted and who wired it. if the engine management light comes on with ignition then the ecu should be getting its power supply and the thing should fire up.

 

the only time i will look towards a igniter pack is IF the fuel pump is running while cranking and there is a trigger signal feed from the ecu to igniter pack but no output signal from igniter.

Hey guys...thanks for the suggestions. I have been out of the country on family issues and just got back to troubleshooting this issue. I had a friend come by while I was gone and he tapped all the fuses with his test light and nothing was out of the ordinary. He also removed the spare tire and confirmed that fuel was being pumped through the system. He was thinking ECU problems.

 

I was going to order an igniter pack like suggested until I read @absz 's post about the engine light. When I fire the ignition, the engine light doesn't light up when I turn the ignition over. So I am assuming I may have ECU problems???

 

Thx....Rosie
