Question: 92 Toyota 3.0 starts and shuts off

[Stanley]

I could sure use some help in troubleshooting this. It starts perfectly every time, but only runs a couple of seconds and shuts down like turning off the ignition switch. The fuel rail pressure stays up. I've gone so far as to squirt fuel in the intake and it will continue to run then so I don't feel its an ignition problem. Each time it happens it will immediately start right back up. Thanks for any advice

so if your injector rail pressure is up but squirting fuel in the intake keeps it running, then the computer isn't sending signal to injectors. I hate computer related ......stuff

Thanks. I agree. I guess I'm going to remove the ECU and send it off to have it tested. I'm not aware of any sensor etc. that would create this problem.
