Mk3 supra turbo won't start after running fine.

89ST · 09-28-2010, 01:30 AM

Hi everyone, I'm new and I apologize now If I'm doing something wrong.

My car is an 89 Supra turbo LHD. The car was running, backed it out of my driveway, went to ingage first and the car shut off. I thought possible i'd stalled it, however it would not restart.

So...
- I didn't run out of gas!
- I have no diagnostic codes popping up.
- if i supply the fuel pump with power if runs.
- fuel pump relay when triggered sounds as though it's functioning.
- car is sparking because when cranked it back fires every so often.

Now when i turn the car to the on position the fuel pump does not seem to prime. nor do i hear it or the fuel pump relay working when i'm the cranking the vehicle. I'm thinking possibly the ecu has bit the dust.

Any other suggestions? Thank you

Any advice is much appreciated.

yes the engine does turnover, the starter is relatively new. I'll check on the fuel smell thing. I haven't noticed it. Not an overwhelming smell anyway.

Thanks for the advice

i don`t know too much about this engines but anything can happen , verify the timming belt or any blown fuse. good luck . Q

Well, if you're sparking that means your timing belt is at least intact (because your exhaust camshaft is spinning). The fuel pump should not prime until your cranking the engine over.

I assume the problem occurred because of how suddenly the engine stopped spinning (from stalling it out). Is your cam position sensor tight? You should not be able to move it at all by hand.

I checked the cam position censor and it is still tight and is not move-able by hand.

The car did shut off very quickly, but i don't believe i stalled. that was just my initial thought because i had no other reason why it would have shut off. I think its more likely when I touched the throttle it died.

u said it backfires? did you check the spark plugs? start from the simple stuff first.
