Question about 1992 Subaru Legacy

Can't find the ECM

I know that that sounds pretty basic, but really it will not start. Right now I am just trying to find the ECM. I have a manual but the ECM is not were the manual says that it should be. Do you have an idea where I should look? I have looked under the glove box as well as under the passanger seat. No luck. So if you could tell me that would be great. Thanks so much

Does the ecm control dash gauges?

Was original PCM dead? Has the 'new' PCM been working at all? The p1602 DTC is set when the battery voltage was detected as low or disconnected. Do the basics and check the battery terminals are clean and tight and that he engine has a good earth lead to the body. Check that battery voltage is 12.4v or higher. Check the fuses and relays. Clear the code and retry to start. If possible try the 'old' PCM if it was working before being swapped out.

I started the car fine and after 2 minutes or so the car died i tryed to start it again and then something smelled like it was burning and smoke came out of the passenger side under the glove box, all the...

The fuel pump is in the tank, and should be accessible through an access panel in the hatch, if you look under the carpeting.

It sounds like something else went wrong with the car though - if it simply was fuel-starved, you shouldn't have gotten the smoke/burning smell. There are a lot of electronics in the dash and any one of them could've fried. Unfortunately without taking some things apart, it's going to be very tough to figure out what caused it.

Start then cut off,won't start back smell gas check spark plugs. they were wet

The fuel pump pressurizes the system and circulates fuel past your fuel injectors. A fuel pressure regulator makes sure there is adequate pressure on the line for the injectors to release the proper amount of fuel when they open (rough explanation). The fuel injectors are controlled by the computer, not really the gas pedal. The computer handles everything for the fuel injection. The gas pedal just opens the throttle plate, allowing more air in. More air needs more fuel, more air and fuel = more power. It all happens very, very fast. Anyway, cranking the vehicle will result in fuel being injected into the cylinders. Without it burning off, yes it could accumulate on the spark plugs and they would appear wet. To work properly, the engine needs (basically) air, fuel, spark, and compression. The timing has to be perfect too.
Look up a quick test on the IPDM ECM relay test. You swap the relay for the computer with one for foglights and test to see if it'll start. That ECM relay has been know to rust internally and fail. Swapping with the foglight relay is merely for testing/troubleshooting purposes. If it works, then you should purchase the proper relay.
There could be many other causes, but this one is pretty easy to try.

Replaced ecm in my 95 f259 5.8, and now it won't shift

Did you put the ECM in from a donor vehicle? (Used). It might have to be reflashed as it sounds like compatibility issues. Make sure the ECM has the EXACT SAME NUMBERS in the ID as your previous ECM. If not, then you will need to get the exact match to get rid of the gremlins.

1989 Buick Lesabre Stalling When Putting in Gear

I have seen this happen when the ground connections on the computer ECM are bad. When the car is in park the ECM is not reading the oxygen sensors and when you put it in gear, it does. When the ground is bad, the voltage pulls back through the sensors because the original ground is bad. This makes the engine run really bad.

First check and see if you have spark at the sparkplug if you do then you need to check your fuel pressure.It sounds like to me that your fuel pump has went out to lunch.When you turn your ignition on try and listen for the fuel you should here it for the first 2 seconds you turn the switch on.

: Sounds like you have attacked the problem pretty well. Check the fuses. Do a "pin" check for power and ground to the ECM. When you replaced the ECM, did you use a new prom? If not, you could have a faulty prom. Check fuel pressure and using a Noid light check the pulse at the injectors. For your information, the injectors will have 12-volts and the computer momentarily grounds them to open the injector.
Your problems may be caused by a faulty ignition switch or starter solenoid.
Intermittent electrical problems are difficult to trace. We would suggest first checking the ignition switch and next the neutral safety switch
You are close to the right track but check the fuel pressure during the no start condition as you may have a faulty fuel pump. You also could have a vehicle speed sensor problem

2002 chrysler 300 M 3.5 liter immediatly quits after starting.

The ECM is most likey the culprit but I would check ground wires and wiring harness to be sure they aren't faulty. With you telling me the voltage is too high, it pretty much points to wiring but the ECM may have gone bad and its just sending blind signals hence the high voltage. The engine light isn't coming maybe because of the ECM isn't working. Pray it isnt the ECM, its costly but exhaust your options by checking wiring and ground beforing fingering the ECM
