Hey guys,

I tried the search button but could not find what I was looking for. I drive a Toyota Aristo V300VE which has the same 2JZ-GTE engine as you Supra folks. It comes with some minor mods: piggyback ecu (unknown, from previous owner), HKS SSBOV, Apex'i AVC-R, HKS super megaflow intake and TRD exhaust and Clifford Matrix 3 alarm.

Anyway, I was installing a turbo timer the other day and it was at night so I left the dome light on for quite a few hours and sure enough, the next day the battery was drained and went dead. I had to go out of town the same day so I figured, screw it, I will fix that when I came back in 2 days.

So, I was back and tried to jump-start the car in the morning and the car starts up just fine. I thought i'd let it idle for a few minutes while the battery recharges itself. However, after maybe about 3-5 minutes, the battery dead error light turns on on my dash and the car chugs and dies. So I thought, oh this battery is bust. I called up a service where a guy would come over and take your old battery away and installed a new one for you. I had to go to work immediately so I had someone wait and watch over while the guy came over to do the battery swap.

Anyway, I was at work and my friend called me and told me the battery was swapped and the car was running fine for a while before it mysteriously stalled by itself. I rushed over home as quick as possible and sure enough, he was right.

The car would start, idled at 600 rpm for 5 seconds, then stalls immediately. Sometimes, it would start, then idled at 600, 500, 400, chug chug chug, 200, stalls. The worst time would be when I started it up and it died just as quickly (turns on, 600 rpm, dies). Also, if it managed to idle for that 5 seconds, I would press on the gas pedal hoping to get the rpm up but the car won't respond at all and dies almost immediately.

I eliminated the alarm ignition kill system because the Clifford tech came over and checked it out and bypassed the alarm system completely and the car still won't idle. It just keeps stalling. I also resetted the ECU several times (even leaving the battery off overnight). I checked the EFI fuse and it was fine. Radio, a/c, lights, all work fine in the "on" position.

Car has 17,000km (13,000 miles or thereabout), recently switched to full-synthetic mobil 1 15w-50 right before turbo timer install.

Any help would be very very appreciated.

there was no chance you left the key on and hurt the fuel pump is there? just an idea! If so.. take the fuel cap off and listen for the pumps or if you have a guage make sure it is ok. Also, check around the battery area and make sure the tech didn't accidently unplug and sensors like the map, etc. I don't know anything about your car.

just sit there and hold the gas, until the ecu relearns itself,

or you can just adjust the acceleration wire via some hex screws

It won't hold the gas. The second my foot touches the gas pedal, the car would stall immediately. On the chance that it's still attempting to idle, my foot on the gas has absolutely no effect of raising the rpm at all.

Make sure the nuts on the thottle and cruise control wires going to the throttle body are tight. My car did that after my single install because the nuts weren't tight on the cruise wire.

To me it sounds more like an electrical problem but give that a look see anyway. Also make sure the pos and neg wires are very tight on the terminal. A bad ground would make it die as well.
