Has spark, compression and gas but wont start. Turns over though. I tried so hard that fourth cylinder filled with gas hydro locked the engine. removed the spark plugs to get the gas out and to turn it again. When i removed the injector rail it started for a second. I guess it is not getting air

Clearing Codes
2TZ-FE ENGINE
Engine and Automatic Transmission
After repair of the circuit, the diagnostic code(s) must be removed from the ECM memory. With the ignition turned OFF, remove the 15 amp EFI fuse for 30 seconds or more. Once the time period has been observed, reinstall the fuse and check for normal code output.

If the diagnostic code is not erased, it will be retained by the ECM and appear along with a new code in event of future trouble.

Cancellation of the trouble code can also be accomplished by disconnecting the negative battery cable. However, disconnecting the battery cable will erase the other memory systems including the clock and radio settings. If this method is used, always reset these components once the trouble code has been erased.

All models equipped with the 1991–95 2TZ-FE engines utilize the OBD I system.

Make sure the battery voltage is at least 11 volts.
Make sure the throttle valve is fully closed.
Place the gear shift lever in Neutral. Turn all accessories off.
The engine should be at normal operating temperature.
Using a jumper wire, connect terminals TE1 and E1 of the Data Link Connector 1 (DLC1).
NOTE: Some aftermarket companies have a scanner which just slides into the DLC1


Turn the ignition switch ON, but do not start the engine. Read the diagnostic code by the counting the number of flashes of the malfunction indicator lamp.

Fig. 1: Count the number of flashes on the CHECK ENGINE light



NOTE: The check connector is located under the drivers seat.



Codes will flash in numerical order. If no faults are stored, the lamp flashes continuously every 1?4 second. This is sometimes called the Normal or System Clear signal.

Fig. 2: A normal system operation will illuminate the light every 1?4 second




The light will blink a number of time equal to the malfunction code indication as follows:
Between the first and second digit, 1.5 seconds.
Betweeen codes, 2.5 seconds.
Between sets of codes 4.5 seconds.

The code series will be repeated as long as the check connector terminals TE1 and E1 are connected. In the event that there many be more than one trouble code, indication will begin from the small value and continue to the larger in order.
After the diagnosis check, turn the ignition OFF and remove the jumper wire.
Diagnaotic codes 25, 26, 27 and 71 use 2 trip detection logic. With this logic, when a malfunction is first detected, it is temporarily stored in the ECM memory. If the same symptom is detected again during the second drive test, it causes the CHECK warning light to illuminate. The 2 trip repeats the same mode a 2nd time.
NOTE: The ignition switch must be turned OFF between the 1st and 2nd time. In the test mode, the CHECK engine light illuminates the 1st time a malfunction is detected.

Compare the codes found to the applicable diagnostic code chart. If necessary, refer to the individual component tests in this section. If the component tests are OK, test the wire harness and connectors for shorts, opens and poor connections.
