Is It Flooded?

[FLASupra]

This happened to me once, when I owned a rotary car (RX3), I stalled the car and it would not start again, and it turned out it was flooded.
The real problem here is my 89 Supra turbo stalled on me when I was backing it into the garage, and it will not start now. The AEM wideband gauge reads 15.1 and goes up a little when I crank the car, the car was running fine up until I stalled it, is it flooded?

Sounds to me like a classic case of heat soak.

Have you tried it again yet?
Give it like a half hour or more. It should start up

Seems like the cause is either a faulty Fuel Pressure Up VSV or the Fuel Pressure Regulator itself.

you cant flood an EFI motor.

heh beat me to it.

It isn't easy, but you can. Pumping the acclerator or stepping on it less than WOT will send voltage through the TPS resistor, instead of IDL contacts, and the injection will increase.

Guys,

Thanks for the replies, I will have to troubleshoot the problem more today. I just got wound up with the flooding problems from the rotary world I was living in, similar problem :aigo:

Have you tried it since? It should have straightened out by now if it was simply heat soak

You guys were right, it fired right up!

Thanks

 

[supra90turbo]

Excellent!
It's still a problem, though... Good luck!

You probably have a component failure. The low cost way would be the FPU VSV. A more costly way would be an ignitor, or a fuel pump and regulator.

 

[supra90turbo]

Yep. I vote VSV, probably the FPR though.

 

[FLASupra]

I'll look into the VSV..............Thanks

On this VSV topic, I have a question. I have good reason to believe that 100* coolant poured out on to my VSV more then once over the weekend when a bypass hose was leaking, and then even more when I fixed the leak.

The next day on my way home from the USGP, I started it after filling up with fuel and I immediatly noticed the FP was way high (3.2kg/cm instead of 2.2) and it wouldn't change from revving the engine. So I shut the car off, waited like 10 seconds, started it again and it was fine. Is it possible my VSV is now on the fritz or is it a regulator problem?

Disconnect the Vac line from the VSV to the FPR...you should get an increase. If you don't, bypass the VSV with a vac line from the TB source directly to the FPR and see if it decreases. If it does, you have a leak somewhere in the VSV loop or the VSV is stuck closed. The TRSM has a procedure for testing the VSV in the FI section.

The sugar in coolant(don't drink it) gets sticky when left uncleaned. It could lock up the solenoid.
