First check all pcm fuses and ignition fuses. Pull them and put them back in if they are good. then check the grounds for the ECM. Then check the data wires to the ECM. Volt/Ohm meter is needed

SOURCE: check engine light came on

Generally this happens because these codes were reset at a dealership etc. These problems should have been corrected before the codes were reset (reputable dealer). A common reason that these codes come on is because of excess hydrocarbon emmissions with a misfire. If this was a temporary event, the light would reset. Since it continues, another likely reason is the oxygen sensor in the exhaust system has failed.

2006 explorer dies did crank and crank replaced fuel pump and starter now when starting instrument pannel goes blank


The first thing to do would be to have it checked for DTC'S - diagnostic trouble codes . Not at auto zone , thier diagnostic system can not pull codes from BCM - body control module or from the instrument cluster . Are you familiar with C.A.N . - controller area network ? All the control modules on your vehicle talk to one another on a serial data bus or network . Your vehicle has a number of these modules , PCM - engine computer , SJB - smart junction box , air bags , ABS , An someothers . All the instrument gauges and the lighting happen over this data bus .
How to Diagnose Controller Area Network CAN Your best bet mite be to take it to the dealer or some other qualified repair shop .

Is there spark getting to the spark plugs ? Is there fuel pressure, check with fuel pressure gauge . Is there an anti-theft system light lit on the dash ? SECURITY light ? Can a scan tool communicate with the vehicle modules ? PCM , BCM , ABS , Air bags , etc... You should test before replacing parts ! No Start Diagnostic Basics EricTheCarGuy

I have multiple codes instrument cluster codes: u1073, u1262, u1059, u1123, u1041; ABS/TCS codes: u1073, u1262, C1805, B2900;


Did you change any modules on the vehicle ?
B2900 VIN Mismatched ABS Module VERIFY that the module has the correct as-built data.
CHECK for correct powertrain control module (PCM) and ABS module configuration using the diagnostic tool. RECONFIGURE the component as necessary. FOLLOW the diagnostic tool directions for the ABS module configuration or REFER to Section 303-01A or Section 303-01B for the PCM. CLEAR the DTC. REPEAT the C1805 Mismatched PCM and/or ABS/TC Module ABS Module CHECK for correct PCM and ABS module configuration using the diagnostic tool. RECONFIGURE the component as necessary. FOLLOW the diagnostic tool directions for the ABS module configuration or REFER to Section 303-01A or Section 303-01B for the PCM. CLEAR the DTC. REPEAT the self-test. U1073 SCP (J1850) Invalid or Missing Data for Engine Coolant PCM REFER to Powertrain Control/Emissions Diagnosis (PC/ED) manual. U1262 SCP (J1850) Communication Bus Fault Network Fault REFER to Section 418-00 . Can a scan tool communicate with all the modules on the vehicle ?
  • The anti-lock brake system (ABS) module or stability assist module (if equipped) does not respond to the diagnostic tool
  • Circuit or connection in the standard corporate protocol (SCP) network.
  • ABS module.
  • Go To Pinpoint Test A .
U1123 Invalid or Missing Data For Odometer Instrument Cluster Go To Pinpoint Test G . U1059 SCP (J1850) Invalid or Missing Data for Transmission/Transaxle/PRNDL PCM REFER to Powertrain Control/Emissions Diagnosis (PC/ED) manual. U1041 SCP (J1850) Invalid Or Missing Data For Vehicle Speed Instrument Cluster REFER to Section 413-01 . U1041 SCP (J1850) Invalid Or Missing Data For Vehicle Speed Tire Pressure Monitoring System Module REFER to Section 204-04 . You need to take it to the dealer , not a transmission shop. Your vehicle could have a ground issue , could have power issue , could have a control module issue . It needs to be hooked up to the factory scan tool ! It is for sure it has a communication problem on the SCP data bus , do you know what serial data communication is ?
The vehicle has 3 module communication networks:
  • the standard corporate protocol (SCP) communications network
  • the international standards organization (ISO) 9141 communications network
  • the universal asynchronous receiver-transmitter (UART) based protocol (UBP) communications network
The diagnostic tool connects to all 3 networks through the data link connector (DLC). This makes diagnosis and testing of these systems easier by allowing one diagnostic tester to be able to diagnose and control any module on the 3 networks from one connector. The DLC can be found under the instrument panel between the steering column and the radio.
The SCP communications network will remain operational even with the severing of one of the bus wires. Communications will also continue if one of the bus wires is shorted to ground or voltage, or if some but not all termination resistors are lost. The SCP communications network allows inter-module communication.
The ISO 9141 communications network does not permit intermodule communication. When the diagnostic tool communicates to modules on the ISO 9141 communication network, the diagnostic tool must request all information, or initiate module commands.
The ISO 9141 communications network will not function if the wire is shorted to ground or battery voltage. Also, if one of the modules on the ISO 9141 communications network loses power or shorts internally, communications to that module will fail.
The UBP communications network will not function if the wire is shorted to ground or voltage. The UBP is different from the ISO communication network in that it allows intermodule communication.

Car wont start 1996


the ecu controls the power to the pump and injectors. are you getting error on every test on reader that can be the ignition relay. its in the dash when you turn the key should hear it go click click. if just one click then one side of it has gone. there is the low volt side, ignition interior dash lights etc. high volts is ecu abs, air bags. etc. low volts go to the abs and ecu but when engine started it needs the high volts to be there to run.

NEED HAVE VECHICLE CODE SCANNED FIRST LOOK FOR FAULT CODES MANY THINGS WILL CAUSE NO STARTING,LIKE BAD CRANKSHAFT POSITION SENSOR.FAULTY CAMSHAFT POSITION SENSOR,BAD SPARK PLUGS FOULED OUT BY FLOODING ENGINE DUE TO LEAKING FUEL INJECTORS,BAD ENGINE COOLANT TEMPERATURE SENSOR,BAD MASS AIR FLOW SENSOR.FAULTY ECM. CODE SCAN VECHICLE FIRST.IF NO FAULT CODES CAME UP YOU COULD HAVE FAULT IN FUEL SYSTEM, COULD HAVE STOPPED UP FUEL FILTER,BAD FUEL PUMP RELAY OR FUSE THE FUEL PUMP COULD BE FAULTY. TURN IGNITION SWITCH TO ON POSITION LISTEN FOR FUEL PUMP OPERATION IN FUEL TANK, YOU SHOULD HEAR FUEL PUMP RUN FOR FEW SECONDS THEN TURN OFF.IF NO FUEL PUMP BAD MORE LIKELY BUT CHECK FUSE AND RELAY FIRST BEFORE BUYING NEW FUEL PUMP.DONT BUY NEW PARTS HAVE VECHICLE CODE SCANNED FIRST USING DIAGNOSTIC SCANNER YOU COULD HAVE BAD CONTAMINATED FUEL.
