ECU location

Hello,

The engine control module is located behind the glove box next to the TCM here is a diagram below to show you. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

If you are having a problem with engine running you should scan for codes and check fuel pressure as it may not be the ECU. See picture for location and see link for fuel test.

You can it should. Be plug and play just don't bend any pins and if a prom unit inside old one put in new one

SYSTEM DESCRIPTION
The ignition timing is controlled by the ECM to maintain the best air-fuel ratio for every running condition of the engine.

The ignition timing data is stored in the ECM. This data forms the map shown.

The ECM receives information such as the injection pulse width and camshaft position sensor signal. Computing this information, ignition signals are transmitted to the power transistor.

E.G, N: 1,800 rpm, Tp: 1.50 msec A °BTDC

During the following conditions, the ignition timing is revised by the ECM according to the other data stored in the ECM.

At starting
During warm-up
At idle
At low battery voltage
During acceleration

The knock sensor retard system is designed only for emergencies. The basic ignition timing is programmed within the anti- knocking zone, if recommended fuel is used under dry conditions. The retard system does not operate under normal driving conditions.

If engine knocking occurs, the knock sensor monitors the condition. The signal is transmitted to the ECM. The ECM retards the ignition timing to eliminate the knocking condition.

Did you check the crank position sensor and are there any trouble codes?
