20 Most Recent 1994 Toyota 4Runner Questions & Answers

limited info generic answer seem to have a few things wrong ---driving through [puddle] may have or did damage electrical system like alternator which is not charging battery causing stall no start -but will need to test the battery alternator and electrical system ---also operating without oil water could also have gotten into engine and pretty much damage /destroy it need to inspect and check internals of engine

For many of the 90's and 2000's Toyota various models - Camry, Tacoma, 4 Runners, Corolla, and some other models it is usually caused by temperature sensitive fan switch on the radiator not operating. Electric fan on the radiator should operate when temp above 200 degrees. Less often the control relay 90987-03003 is defective. Check if bubbling in the radiator smells like exhaust. That would indicate a blown head gasket. A jumper wire from your marker light positive to the lower contact in the fan control relay socket will operate your fan when parking lights are on. The larger vehicles with more powerful radiator fans will need a hefty jumper from a headlight positive to avoid overheating the lighting wiring. Make sure the engine is off and warmed up to check the radiator core with your hand to see if it is getting circulation. If it is all cold the thermostat might be stuck.

Well the 1st thing that should have been checked was the engine control module for fault codes, buy a OBD2 fault code reader or borrow one from Autozone or other parts store. Post results here. This test is NUMERO UNO, ALWAYS.

Have you tried spraying quick start in the intake while cranking? If it tries to fire then it is fuel related, but if not is electrical related.

That sounds like an air leak in the intake manifold area. If there is no hose off,it could be a intake manifold gasket problem If you need further help, reach me via phone at https://www.6ya.com/expert/gary_9c859f4aa7e5ab10

Sounds like you have a fault in the coolant temp sensor circuit. If the PCM does not get the proper engine temperature, it will have trouble delivering the proper fuel charge to run the engine. The other possibility is either a plugged fuel filter, or a weak fuel pump. Check your fuel pressure, and if you haven't serviced the fuel filter in a while, start there with a new one and then do the fuel pressure test next, followed by the coolant temp sensor, but you will need a scan tool for that.

read the fault codes to determine the fault area

Look for the transmission control module to see if it's sending voltage to the shift solenoids.

When alarm goes off,put key in ignition and turn,the alarm should go off and alarm should be reset.Or,remove positive battery cable,wait 10 minutes,reconnect,when you open door,alarm will sound,insert key in ignition and turn key and alarm should go off and alarm should be reset.

The transmission depends on input from the vss, crank sensor, and tps for shift points. Assuming the speedometer is working, I recommend you run the test below on the tps. Also put the connector back on the tps and check the voltage on terminal VTA with the key on by probing the back of the connector. Open the throttle gradually and verify that the voltage increases linearly with throttle opening. If not, replace the tps. Throttle Position Sensor OPERATION Throttle position sensors are usually mounted on the side of the throttle body. The sensor detects the throttle valve opening angle. The voltage of terminal VTA increases in proportion of the opening angle of the throttle valve. The ECM judges the driving conditions from the input signals of the terminals, and uses them as one of the conditions for deciding the air/fuel ratio correction, power increases and fuel cut-off control. TESTING 3VZ-E and 1FZ-FE Engines

1. Confirm that the throttle valve is fully closed.
2. Connect an ohmmeter to terminals IDL and E2.

E2 is the bottom terminal, while terminal IDL is positioned directly above it.

3. Insert a 0.020 in. (0.50mm) thick feeler gauge between the throttle stop screw and lever. Check for continuity between terminals IDL and E2 of the sensor. Continuity should be present. 4. Insert a 0.031 in. (0.80mm) thick feeler gauge between the throttle stop screw and lever. Check for continuity between terminals IDL and E2 of the sensor. Continuity should not be present.

YOU replaced the driveshaft ... or did you pay somebody else to replace it? Are you sure it was actually replaced?

The perils of used transmissions is all I can say is have it rebuilt.

Autopartstore has it online..they will it up
