How do I know if it's the ECU? 200 1990

Dear Lordy,

I think it does. That is good news.

Two problems to overcome first. The morning will arrive an hour late and your first attempt to fix will force you to stand on the traffic side of your car (facing North of course).

A dead car.

Does it crank (make rrrr--rrrr noises while you attempt to start it)?

Does the cam turn? (Remove oil cap, look in while assistant cranks)

Well, because you were approaching the intersection from the East, I'd say it is just your wiring where the 25A fuse supplies the fuel injection and ignition computer -- the one near the battery.

If you had been approaching from the North or West, it would certainly be the timing belt or -561 ECU. An intersection approached from the South usually stimulates a fuel pump relay overheat and open. Failure to run after the intersection is cleared is always the same regardless of the direction of travel: AMM failure.

Glad it was only a mile away, not a bad walk. Take a wrench to remove a spark plug so you can test spark. If the fuel pump relay is suspect, give it a sharp rap (located above passenger's feet in a white box). First time you turn the key (assuming it isn't stone cold dead as in no battery) listen for a short run of the fuel pump.

But, if I'm right about the 25A fuse circuit, be prepared to clean up any corrosion on that red wire and the fuse holder next to the battery.
