Does this motor have the equivalent of crank-trigger ignition? If so, is the sensor A-OK?

2000 tundra V8, no codes, but misfire and lack of power upon acceleration


A misfire will produce codes. Look at the cam position sensor, the throttle position sensor and the MAP sensor. If they all check ok then you'll need to check the computer.

Lost power in celsior v8


what country
4.0 L 1UZ-FE V8 its a fuel injected V8. used in Lexus LS400s in USA.
i restore old cars and 1990 is old.
lost power can be misfire , does it do that hot /cold or both engine temp? loss power, under what coolant temps.
so if the tranny dont slip or brakes drag. (car rolls easy) then
the engine is sick , this is an EFI engine.
on all old engines. Get a real FSM, for sure.!!!
  1. check compression, first. 150psi or more. good on all 8 (W.O.T)
  2. tune it up, wires plugs, cap ,rotor.. filters. (all)
  3. Ignition timing: 8 -12deg BTDC @ idle (Transmission in neutral position)? 1-8-4-3-6--7-2, firing order sparks wired right?
  4. I then make sure fuel pressure is at spec,
  5. at the same time. the classic injector leak down test.
  6. at the same time, the classic, injector balance test.
  7. With all that good the EFI system has hope.
  8. I then check the ECU for DTC errors, (flash codes )an address all those.
  9. the eng. thermostat get to 180F or more fast and holds !!!
  10. if clean the MAF a dirty MAF, will cause lean and lean causes bogging and huge loss of engine power
  11. does the engine hold closed loop. at idle and at 2500 rpm in neutral (hot engine) id bet not.
  12. no scan tools so all you have is a blinking CEL lamp test so do that check. The check jumper wire.
  13. on these old dogs, i must check every sensor by hand due to no SCAN tools in 1990
  14. thats enough, for now. I see wasted spark coil packs, got misfire?

2001 toyota tundra wont turn over and smelling gas


flooding (check fuses , always)
has 50 causes.
ever do the service on this engine?
which engine?
3.4 L 5VZ-FE V6
190 horsepower (2000-2004)
4.7 L 2UZ-FE V8
245 horsepower (2000-2004)


if the engine is not bad, (bad compression, do to skipping service)
its lost park or is excessive fuel injection
ir sure park is good (simple test)
we use the opr, guide way called unflood mode.
you crank with throttle at WOT, wide open throttle , this act cuts all fuel
and she starts.
if not , its got bad spark or bad engine.

there are just 3 tests
1: compression good.
2: spark good to all cyl.
3: fueling checks.
sometimes its lack of air , (fails #3) and that is because the cold start air supply is DEAD> causing rich starts.
so start car with 10% throttle, creating a virtual start up air supply.

its one of those 3, we use a set of $60 guages to find it.

6th cylinder misfire. replaced spark plug and ignition coil 6 months ago and already misfiring again.Is this a problem with 2000 toyota tundras or is this normal to have to change spark plugs and ignition...


Did u find code p0306 comes up ? Two things can cause this if the plug and coil have been replaced.the intake manifold may be leaking in the area of cyllinder 6 or its a mechanical issue.try doing a cyllinder misfire test and also check the compression on all cyllinders

I am showing a #7 misfire on my 2000 tundra v8 4.7l. Have changed sparkplugs and still have same problem. Is there a way to test this ignition coil?


You can switch ignition coil to the other cylinder to check if the misfire follows that pack. Or check for ohms.

In a Toyota Tundra v8 4.7l, after I change the Timing Belt, why does Check Engine comes on, and it shows Troubleshooting P0340.


Symptoms Symptoms can include:
  • Hard starting or no start
  • Rough running / misfiring
  • Loss of engine power
Causes A code P0340 could mean one or more of the following has happened:
  • a wire or connector in the circuit could be grounded/shorted/broken
  • the camshaft position sensor may have failed
  • the PCM may have failed
  • there exists an open circuit
  • the crankshaft position sensor may have failed
Possible Solutions With a P0340 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
  • Visually inspect all the wiring and connectors in the circuit
  • Check for continuity in the circuit wiring
  • Check the operation (voltage) of the camshaft position sensor
  • Replace the camshaft position sensor as required
  • Check the crankshaft position circuit as well
  • Replace circuit wiring and/or connectors as required
  • Diagnose/replace the PCM as required

2000 Toyota Tundra 4.7L V8 Rough Idle


Clean/Inspect Intake, MAF sensor, IAC valve for proper operation. Also check for vacuum leaks within the air intake hose and intake components. Hopefully this helps
