Limited performance now wont start

Usually you can lock all the doors. Open the drivers door with the key, this will unarm the security. If not, try the passenger side.

p1248 is in the same error codes as the rest now i have been a mechanic for plenty of years and i will tell you it will be the glow plugs they have a certin limit to glow to start the car if they are worn or nearly gone they wont hold all the fire in them ,,,,Injection start control deviation means the car is not getting even to kick start it it maitanes and shuts the engine down if there is a problem i suggest you changed the plugs and see how you go here is a link to see http://www.patentstorm.us/patents/5778852/description.html

what does the scan tool show.??
? still P0106, and did you reset it?
did you try to start car with MAP disconnected, some do start in limphome mode. rich a a pig but starts.
did you have key off when you fiddled the MAP connector,
or better pull the battery neg, lug first?


lost power to the mAP, check the power pin.
lost ground to sensor.
lost vacuum to the sensor (clogged paths)
Bad MAP sensor Water/dirt intrusion affecting MAP sensor connector Intermittent open in the reference, ground, or signal wire for the MAP sensor Intermittent short in the reference, ground, or signal wire for the MAP sensor Ground problem due to corrosion causing intermittent signal problem A break in the flexible air intake duct between the MAF and the intake manifold Bad PCM
(do not assume the PCM is bad until you've exhausted all other possibilities)

do you have good battery power? Is your alternator charging?
fuel pump will quit working wile you driving to! Or furl filter restricted?
Over 100'K is the timing belt to be inspected!
Start with basic and post more information.

something with ignition is failing--or maybe a wire gettn hott--a code like that is combustion related--hav a data stream run to give u values of engine performance--an independent shop or mobilemech has the equipment

Clean the battery cables this may be a corrosion problem, also test the battery and the charging system performance.

The check engine light being on now is a different problem , Have DTC'S - diagnostic trouble codes checked ,will have something to do with electronic throttle control . That is what reduced engine power is about . It's in a reduced power mode.
Reduced Engine Power Mode
When the ECM detects a condition with the TAC system, the ECM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
• Acceleration limiting--The ECM will continue to use the accelerator pedal for throttle control; however, the vehicle acceleration is limited.
• Limited throttle mode--The ECM will continue to use the accelerator pedal for throttle control; however, the maximum throttle opening is limited.
• Throttle default mode--The ECM will turn off the throttle actuator motor and the throttle will return to the spring loaded default position.
• Forced idle mode--The ECM will perform the following actions:
- Limit engine speed to idle by positioning the throttle position, or by controlling the fuel and spark if the throttle is turned off.
- Ignore the accelerator pedal input.
• Engine shutdown mode--The ECM will disable fuel and de-energize the throttle actuator.

Do you know what electronic throttle control is ?
--------------------------------------------------------------------------------
Throttle Actuator Control (TAC) System Description

The throttle actuator control (TAC) system delivers improved throttle response and greater reliability and eliminates the need for mechanical cable. The TAC system performs the following functions:
• Accelerator pedal position sensing
• Throttle positioning to meet driver and engine demands
• Throttle position sensing
• Internal diagnostics
• Cruise control functions
• Manage TAC electrical power consumption
The TAC system includes the following components:
• The accelerator pedal position (APP) sensors
• The throttle body assembly
• The engine control module (ECM)

Your best bet , take it to a qualified repair shop .

Check teh big fuses in the power distribution box near teh battery under the bonnet

Every morning at lunch time and evening my jeep won't start. It doesn't grind but the electrical goes crazy. After a couple of trys it finally starts. Help

if the security light is on it could be the ign lock cylinder, it has two small wires attached to it and one may be broken and are the keys the ones that came with the vehicle
