Verify good fuel pressure (30-40psi) if that checks out ok, then loosen exh pipe at exh manifold, so there is a 1/2" gap, an dtest drive,if it then has power, the cat canverter is plugged and will need replacement.

I have got toyota noah which wont start. the cranking its there. battery is good. there is no powere to fuel pump. fuse all ok. even changed the engine control unit.


If the vehicle is fitted with an immobiliser that could be the problem. Have you checked for a spark?

If an immobiliser is fitted the new engine ECU will have to be coded before it will work.

A wiring diagram is almost essential to diagnosing the problem. There is likely to be a relay controlling the supply to the fuel pump but what controls the relay? If the relay is controlled by the engine ECU there will be no supply until the immobiliser is disarmed.

If the vehicle was presented to me I would check for a spark and if a spark is present I would provide a temporary supply to the fuel pump to test if the engine starts, proving the fault is not immobiliser-related but a wiring or switching problem.

How to get codes back after replacing battery


Hi there,

I'm assuming you are referring to your vehicle's on-board diagnostic codes?????

When replacing the battery (i.e. disconnecting power from the vehicle), this will RESET your vehicle's OBD computer.

When the computer is reset, NO CODES should be present, UNLESS the computer has detected a fault.

Lacks power and acts like its not firing on all cyliders could the timing chain have jumped a tooth ? 1996 4.0L explorer 200,000 miles


Are there any engine codes ? This vehicle is OBD II ! A bad maf sensor will give you poor idle and lack of power and on fords often times no codes ! Another possible cause could be exhaust restriction due to a catalytic coverter being stopped up ? Previous misfires if driven long enough can trash a cat ! Let me know if any codes are present and what they are !

How do I pull codes from a 2000 Toyota Camry 6 cylinder?


You must use an OBD2 reader, OBD2 vehicles do not support self-diagnosis. OBD2 vehicles are years 1996-present!! Bring your vehicle to your local autozone, they would read the codes for free!!

Dodge ram trouble codes p0298 and p0296


P0296 Cylinder 12 Contribution/Range Fault
Is triggered when the Power Train Control Module (PCM) detects that the acceleration rate of the crankshaft for Cylinder #12 was less than a calibrated amount. During normal conditions the PCM turns the Fuel Injectors ON and OFF in the Fuel Injection System.
Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Engine Misfire
- Engine Run Rough
- Low MPG

Possible Causes:
- Fuel Injector #12
- Faulty or Corroded Fuel Injector #12 Connector
- Plugged #12 Fuel Injector
- Dirty #12 Fuel Injector

Possible Solution:
- Clean Fuel Injector #12 Connector
- Clean Fuel Injector #12
- Replaced Fuel Injector

P0298 - Engine Oil Over Temperature Condition
Indicates the Engine Oil Temperature Protection (EOT) strategy in the Power Train Control Module (PCM) has been activated. This temporarily prohibits high engine speed operation by disabling injectors, reducing the risk of engine damage from high engine oil temperature. Note: On engines which are equipped with an oil temperature sensor, the PCM reads oil temperature to determine if it is excessive. When an oil temperature sensor is not present, the PCM uses an oil algorithm to infer actual temperature. Engine shutdown strategy function is the same on vehicles with and without oil temperature sensors.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- Engine Surge

P0298 is set when the vehicle has been running below 1,000 rpm and less than 20 mg/stroke MFDES with EOT sensor signal reading above 110C (230F). The time to set the fault is dependent on EOT and Intake Air Temperature (IAT) temperatures, and can vary between approx. 15 to 45 minutes

Possible Causes:
- Very high engine RPM for an extended period of time.
- Overheating condition.
- Malfunction EOT sensor or circuit (vehicles w/EOT sensor).

Possible Solution:
1. Inspect EOT sensor circuitry at sensor and PCM. Inspect for damage, loose or pushed-out pins, loose or poorly crimped wires
2. If connectors are ok check cooling system, radiator, fan/clutch operation, thermostat
3. If cooling system is ok carry out KOEO On-Demand Self Test
4. If other fault codes are present after test repair them, if only P0298 is present clear codes
5. Let vehicles sit for 8 hours and then KOEO
6. Monitor EOT in live data
7. If EOT sensor reading is above 110*C(230*F) replace sensor
8. IF EOT is below 110*C check continuous memory DTCs
9. If P0298 is present replace PCM

Hope helps (remember rated and comment this).

1993 toyota camry runs sluggish what should i do i think it needs a new fuel filter but not sure car runs fine other than sluggishness idles ok but very little power on take off it eventually gets up to...


Bring it to Auto zone parts store to check if any trouble codes are present they will hook up a scanner for free, the code if present will point you in the right direction if no codes are present the car most likely needs a tune up, when these vehicles get older the fuel injectors become less efficient and need professional cleaning, O2 sensors should be changed every 60 to 80,000 miles whether the check engine light is on or not.

Check engine light is on -lacking power


go to Autozone and have them run a test (it's free) to see what trouble code is present, this will help figure out which part has failed.
