Hey guys, just bought a 96 1jz vvti, with a mongoose immobiliser had it for about a week and I was installing a sub and I'm guessing when I unhooked the battery the immobiliser has gone funny as the car won't turn over now, the immobiliser seems to still lock/unlock but ive tried all sorts of things and tried searching everytjing under the sun but can't seem to work it out, Any help or info you may have would be greatly appreciated!
Oh also! Forgot to add that at first the dash seemed all good and was always there but now the dash wont show when the car is in neutral or park all other positions it lights up, thanks!

were you working around the gear stick? it could be that the micro switch at the gear stick or something unplugged in that area is the problem. The management system does not know the car is in neutral or park, therefor it will not start.
I was yes and I thought that could be the problem I've had a good look around everything seems to be plugged in, but before the dash went funny It showed the n or p on the dash would that mean it's still registering it's in those positions? Also it won't make the same sound when trying to start in the other gears but when in n or p it sounds like more is being activated under the bonnet ?

i would check the micro switches are ok. try selecting P or N and jiggle the gear stick about and see if it comes up on the dash. I would guess your problem is the fault not displaying P or N on the dash and not the immobiliser.

check all fuses inc the box by drivers footwell also check all wires that you disconnected are back in the correct connector, sounds like the g/box inhibitor switch is working as you can hear the relay clicking under bonnet .
I've just rechecked all the fuses and ensured all plugs are connected properly, could the big birds nest of wires behind my head unit stop the car starting? As yous said it won't be the immobiliser I've got that out of the question as when Its locked nothing at all sounds like it's happening when turning the key but when unlocked more is happening, I tried putting a hot wire to the big black wire in the starter relay that goes to the starter motor but nothing happened a little bit of load on the wire but no starter operation, I have an auto electrician coming to rob me today see how that goes!

Can you hear the fuel pump priming? But just nothing happening on the engine side of things? i.e no starter motor engaging?
Reason I say this is I have a 97 1JZ vvti, and I had this issue. It too has a mongoose alarm - my first thoughts were that it was faulty. My issue though was the starter motor was faulty, so I fixed this and all was well.
Hey guys after a couple hours of tryin to find the problem and even cutting out the immobiliser the auto elec found the simple problem and it was where the starter relay plugs in one of the connectors was wedged open a bit so it wasn't making contact properly to engage the starter motor! Simple Little things can really do your head in! Thanks for the help guys!
also the dash has started working on p and n again! But I have a problem now it is idling at around 500rpm and if I put my foot down a little and then slow down it is stalling! Am about to do a search on here for that now but could it be the ecu having been unplugged so is re learning?

Good to hear that its running again & as you said the low idle is the ECU re-learning as the base idle is probably out due to carbon / sludge build up at & around the throttle butterfly so you either drive it for a shortish while & it will come good or pull off the cooler pipe to the throttle butterfly & with a tooth brush or such with some CRC you can crack open the throttle & clean around the opening at the throttle butterfly, carby clean works well too but might melt the bristles on the tooth brush ??
Came all good the next time I drove it mate but might do that anyway to give it a clean! My head unit isn't working now though ha no fuses are blown or anything all plugs are back in could have knocked the earth somewhere probably will have a look for that! Haha cheers mate!
Hey guys, Car has done it again! The starter relay is making contact and even with a hot wire to the starter wire is not turning over the starter motor, it has a load on the wire but the starter won't turn at all, the wire that was loose is now all fixed but I'm wondering if it was just a coincidence that wire was stuffed and also the starter motor was maybe seised as the auto elec did give it a tap, any idea how much a starter motor will set me back if you guys think it could be the problem?

Check that the battery is good & fully charged & the battery connectors & earth connections are good & clean & if all ok certainly sounds like the starter motor is US ..
Not to sure what you would pay for a reco or new one, I'm guessing around $200 for a reco one & around $300 plus for a New one through Repco or Bursons if one is avaiable ??? ( not genuine though as that would be probably around a $1000 plus )
Hey guys I bought a starter motor was very cheap from autobahn, the guy said that it'll fit asked if it was single turbo or tt everything like that, I picked up th starter it's a 1kw says for toyota, the brand is oex enduro, it's slightly bigger but seems to only have two terminals, One is the plug coming from the relay, the other is the normal looking constant 12v one I think, but I can't see a terminal anywhere for the earth? Any ideas where I would put that, can I just undo one of the bolts on it and screw it on there? The model number is rxs414 Also if course Now as soon as I buy the starter it starts every time, lol unreliable though, I'll try send a pic through of it

The old starter sounds like its scared its going to get thrown in the dump master & is now trying to be a good boy
If it the old starter has a earth lead coming off one of the main mounting bolts just refit it onto the new one using the main mounting bolts only, but if there was nothing before don't worry as it should have a good sized earth attached to another bell housing bolt close by ..
It had one on the old one but had a bolt coming out of it and a nut on it where the main earth was attached to, so your saying I should be able to just put that earth on one of the mountain bolts?

The Mountain bolts might be a bit high, just use the mounting bolts
But in all seriousness the mounting bolts are the ones to use as you can get it tightened up quite firmly as opposed to some light tin bracket or such, either way it will work, but if you don't use the main mounts you have to make sure its a good metal contact & not insulated etc etc ..
Okay cool thanks heaps mate I'll get working! Any tips on a way to get the stupid top mounting bolt off the old starter motor. Had lots of trouble finding a tool that fits
