I got my 94 GS300 a few weeks ago 200k miles. About a week after I got it, my mom had a mechanic she goes to replace the power steering pump. When I got it back a few days later, It stalled on the way home. I had 1/4 tank of gas, but since the car was new to me, I wasn't 100% sure the gauge was working. After my girl got home, I put some gas in it and it started right up. Thinking the gauge was bad and I just ran out of gas, I went to fill it up. On the way home, died again. The next morning, it started right up.
Each time it dies, I turn the key and the car sounds like it's about to start, but never comes on. It sounds just like it's out of gas, or how it sounded when I tried starting it while having the fuel pump ecu disconnected. My mom's mechanic replaced the fuel pump, I replaced the EFI relay and fuse in addition to bypassing the fuel pump ecu, but still the same problem. I just started a new job, this is my only car and i'm low on funds. So if i can't get it fixed fast and relatively cheap, it's going on craigslist. (it's actually on there now)


Problem:
After driving car for an undetermined amount of time, it dies. Lights stay on, engine shuts off. I try starting it, but no luck. Car sounds like it's out of gas.

Things i've tried:
New Battery
Replaced fuel pump and fuel filter
Replaced EFI relay and fuse
Fuel Pump ECU bypass mod
Cleaned MAF with 99% isopropyl alcohol (still started afterwards)
New air filter.
Radiator fan runs, no coolant leaks

Note: I noticed oil dripping onto the connector for the O2 sensor closest to the MAF, right underneath all the spark plug wires. It was also inside the connector.

check you ecu, I had a car that had the same problem the capacitors melted and leaked onto the board(swap ecu).

I pulled the ecu and opened it up. I didn't see leaking caps or anything noticeable. Should I still give a new one a shot?

Spraying alcohol into your Karmen sensor is a big mistake. Everyone assumes it's a hot wire mass air meter but it's not. See if you can borrow another one.

I've got my girl picking up a new maf and ecu from a junk yard today. Gonna install them and give an update when I get home from work

Thanks

Hey i sent you a pm....will if you sprayed that on your maf you mite of messed it up....I would go more with maf then ecu....before you put all that stuff on take your battery wires off first.....and put the parts one one at a time try the maf first.

andibogard

Woohoo. Got a replacement MAF for $50 and ECU for $100 from the junkyard. Installed them and did a 30 minute test drive around my neighborhood. Everything seems to be fine! I Gonna put it through a real test tomorrow and drive to work. Thanks everyone!

Let me know how it goes, I'm having the same issue

andibogard

I drove to and from work today. It's about 30 minutes each way and no problems. Good luck with your issue

Now swap back each one to confirm which one was the culprit?

RY2K

yeah
DO IT
I'm curious what it was

andibogard

Damn this peer pressure! I was gonna be lazy and let it go, but I guess I'll do it Saturday.

gulleyman

Awe y-e-a waiting anxiously...

Looks like a bad ECU was the culprit. I played musical parts and both my old ECU and old MAF were bad. The bad MAF is due to me attempting to clean it though.

I was in such a good mood, I decided to clean my rims. I want to swap them for some stock rims and tires, but I have to wait now after putting so much money into fixing this problem. I figured they may as well be clean since I'm stuck with them for a few more weeks

Looks nice
