    Thank you for all your help. I got the engine to crank over and run. However the check engine light came on for the throttle body position sensor and am not really sure how to fix this problem

I'm assuming the spark plugs are ok and have been replaced. Is the engine getting spark to the plugs? I suspect the CKP (crankshaft position sensor) may be causing your starting problem. How many miles are on the Jeep and is this a 4.0 L?

    Spark plugs have been replaced and there is 133000 miles on the engine odomitter but engine has had an overhaul and really only has about 50000 miles on it

  • GetMeOttaHere Jul 10, 2010

    Since most of the parts that could be the cause were replaced, You may as well replace the CKP. Unless you have a scanner, I can give you set values.

  • GetMeOttaHere Jul 10, 2010

    The scanner you have is a code reader? The scanner I was speaking of is a DRBII or DRBIII.

  • GetMeOttaHere Jul 11, 2010

    You read no trouble codes at all?

  • GetMeOttaHere Jul 12, 2010

    What was the code if any for the TPS?

1997 Toyota Corolla Long crank with cold engine normal start and operation after warm engine

hi, i would like to advice you check the electronic idle speed control valve and also check engine coolant temp sensor. The ISC (idle speed control valve) is located somewhere below the throttle valve. the engine coolant temp sensor is located near distributor. it has a two wire connection. the sensor connector is usually green

Engine light on po106 code

  • OBD II P0106

Fault Code Definition
The Manifold Absolute Pressure Sensor/Barometric Pressure Sensor measures the rise and fall of the air pressure inside the Intake Manifold. This provides critical data needed for the Powertrain Control Module (PCM) to control the Air Fuel Ratio, the Ignition Spark Timing, and many components of the Emissions Control Systems. The Manifold Absolute Pressure/Barometric Pressure Sensor P0106 code is set when there is a problematic or erratic performance in the voltage signal to the PCM.


  • Check Engine Light will illuminate
  • In many cases, no abnormal symptoms may be noticed
  • In some cases, the engine may be hard starting and/or get poor fuel economy
  • In some cases, noticeably poor engine performance may occur

Common Problems That Trigger the P0106 Code

  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is defective
  • Intake Manifold vacuum leaks
  • Faulty or corroded Manifold Absolute Pressure Sensor/Barometric Pressure wiring or connections

Common Misdiagnoses

  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real cause is an Intake Manifold vacuum leak
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real cause is a stuck-open EGR Valve
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real problem is a defective Idle Air Control Motor, which causes a very low engine idle

I have replaced my fuel pump, fuel relay and fuel filter. Im not getting power to fuel pump. What should I do next?

If the Cirrus is a 2.5L change the Crank Sensor. The Haynes manual has a good step by step. This sensor will cause a no start. The cam sensor, coil, are built into distributor, and can not be replaced.Less you buy a recon. or new unit.Other problem would be the engine computer.

My saaB 900s try to start But won't . I replaced every thing , Fuel pump, ignition coil, distriButor and ecu But car still wont' start. The engine light was on But after disconnecting the ecu and ICU, now...

If the fuel pump is'nt running then it's a bad relay or blown fuse. If the pump is running then it could be a few things, a bad timing belt, bad cam sensor, bad crankshaft sensor, could be the timing is off which you can adjust with the distributor, or it could be a bad o2 sensor or MAP sensor.

95 accord LX 2.2, starts and stop immediately I replaced the following to date: fuel pump fuel filter injectors new dist new ignition the problem not resolved, any other areas to look?

Look at the crank Position Sensor and the Cam Sensor as well as check the Timing belt for proper operation, if there is a slack of any type in the timing belt the tension device isn't working properly and is the cause of the problem.

Stopped while driving replaced fuel filter and pump and crank shaft senor

I suspect you have a bad camshaft sensor. It is part of the distributor. To check, remove distributor cap and rotor (1 screw for rotor) and check for brown dust. If yes, remove slotted wheel and clean optical sensor. If car starts, you need a distributor.

Crank sensor has no affect on system. It is used for back up only.

Not getting fuel

if you have a 1.8-2.7- or 1.2 engine change the distributor cap and plugs and wires check timing also .it could be problems with the led photodiode in distributor. for the 2.2 and 3.3 it distributorless they have crank sensor and cam sensor. you will need a scanner to check those sensors. check to see which one of theses engines your vechicle have. go from there . your fuel pump relay should be in the engine compartment.
