If the battery was below five volts when you jumped it. It is a normal security feature. It should reset after you put the key in to start.

either trans is no good or you don't have gear linkage hooked up right

if not completely installed remove belt and start over. marks must be directly in line. if you have already completed the installation, you have to dismantle it again to correct this. if trying to set timing without dismantling, the distributor will not be correct and engine timing will be incorrect and run poorly

Your ECM (car's brain) has reduced your car to Limp Mode. You'll need a Fault Code Reader and list of fault codes for your vehicle to diagnose the problems. Fault code readers aren't expensive and Haynes makes inexpensive DIY manuals for your vehicle. Could be the EGR, PCV valve, TPS, or Oxygen Sensors. Each of these has a separate fault code... please check a fault code reader and verify the fault against the list in Emission Controls list in the Haynes manual. This will narrow it down for you.

Try to check the throttle position sensor, or idle control valve is equipped

Hi, the alternator is not needed to start the car, so it may be just fine. Problem is likely in the start circuit.

Please see my tip at http://www.fixya.com/cars/r6222268-engine_doesnt_crank_turn_over . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

Replace your glow-plugs with the proper ones from DENSO.

This could be a bad wheel bearing. If it happens only in a turn, it could be a CV joint. Some brake systems have a brake warning that scrapes on the disk to let you know. It could be bent or out of place. Hope this helps.

There are many issues that can cause this. Most common are fouled spark plugs, clogged fuel injectors, bad Oxygen sensors, PCV valve stuck, broken or disconnected vacuum lines. DFENSO plugs and O2 sensors will fix those problems. Vacuum lines require a thorough inspection using the diagram inside the hood; tracing every line and inspecting for cracks. Your fuel injectors are also DENSO, they can be cleaned using specialized machines... a Bosch service center has the machine to clean them and test the spray pattern for proper flow. Vacuum lines are easy to replace and the PCV valve just screws on. If these don't work, then you have an ECU problem. Rebuilt ones are available on line for around $100.

The P0141 code points to the O2 sensor heater circuit. It could be that there is a short in the wiring to the O2 sensor or it could be that the O2 sensor heating element itself is bad. The code is for O2 sensor Bank 1 Sensor 2. Bank 1 means its the O2 sensor connected to the exhaust pipe that runs to cylinder #1. Sensor 2 means that it is likely the O2 sensor after the catalytic converter on the same exhaust pipe.

Sorry for the delayed response. For future reference, the blower motor resistor in an 04' Honda Accord is located under the glove box and a little to the left if you are facing it (the glove box). You just need to pull out the plastic panel (yes, you can just pull it out by hand, no tools needed for that). It should be right on the fire wall with a plug going into it. If you reach in there and pull the plug (it has a little notch so it clips into the resistor more securely; make sure you push the clip in) it should have 4 flat prongs on it that go into the resistor. The resistor itself will have 2 phillips head screws that are holding it into the fire wall. Unscrew them and you have the resistor. If you can unscrew both screws before unplugging, it will be easier to see how it unplugs. I know this sounds complicated but once you get in there you will notice it's fairly easy to change out.

Try using a carburetor cleaner instead, as it has some lubricants in it's makeup that can actually help the moving parts.

P0780 Automatic Transaxle Malfunction (With Automatic ... P0780 Automatic Transaxle Malfunction - With Automatic Transmission Possible Causes Setting Conditions

• Mechanical problems present in the automatic transmission can cause this code to set. See the note below.
• Refer to the repair instructions in a transmission repair manual or the information in other electronic media to repair this code.

Engine running; vehicle driven at Cruise speed, and the PCM detected a problem in the mechanical operation of the automatic transmission. Note: This trouble code (P0780) sets with along with several TCM related trouble codes.he Malfunction Indicator Lamp The Malfunction Indicator Lamp (MIL) alerts the driver that the Powertrain Control Module (PCM) has detected an OBD II emission-related component or system fault. When this type of malfunction occurs, an OBD II Diagnostic Trouble Code (DTC) will be set by the PCM. The MIL is located on the instrument cluster and is labeled CHECK ENGINE, SERVICE ENGINE SOON, or is identified with an ISO standard engine symbol (i.e., a picture of an engine). Bulb Test Each time the ignition switch is turned to the "on" position, the MIL indicator is illuminated for about 3 seconds (which is a function of the PCM). Readiness Codes To check if the Readiness Codes are set to complete, turn the ignition switch "on", but do not start the engine. The MIL will come "on" for 15-20 seconds. If it then goes "off", the Readiness Codes are set to complete, If it flashes five times, one or more of the Readiness Codes are not set to complete. To set Readiness Codes from incomplete to complete, perform the drive cycle procedure for the appropriate code. MIL Lamp-On Message Each time the PCM detects an Emissions related fault, the MIL is illuminated to inform the driver that the vehicle needs to be taken in for service. COMPONENT MONITOR DRIVE CYCLE INSTRUCTIONS

• Do not turn off the ignition switch during the test procedure.
• All Onboard Diagnostic Monitors are cleared when the battery is disconnected or when the Powertrain Control Module (PCM) is cleared with the Scan Tool.
• This drive cycle can be used to determine if the Readiness code for this Monitor will run and complete, and if the MIL will remain off after the vehicle is driven.
• Operating Ranges: When a range of values is provided, try to operate the vehicle in the middle of the range. For example, if the vehicle speed range calls for 45-55 mph, drive the vehicle as close as possible to 50 mph. If the engine speed should be 1,000-2,000 rpm, try to operate the engine at 1,500 rpm.
• Scan Tool Data: There are certain Parameter Identification (PID) values that must be within range before this Monitor will "run". It can be helpful to pull up those PID items on the Scan Tool so an assistant can view them during testing.
• The Readiness code for this Monitor defaults to "continuous" or "monitoring" because this Monitor runs continuously when the engine is cranking or running.

COMPONENT MONITOR PRETEST CONDITIONS

• MIL is off.
• No Emission related DTC's are present.

TEST PROCEDURE

1. Connect the Scan Tool to the data link connector (DLC). Use the Scan Tool to clear any stored DTC's and to reset the OBD Monitors.
2. Start the engine and allow it to run at idle speed for 15 seconds.
3. Accelerate at part-throttle to 40 mph and maintain that speed for several minutes. Bring the vehicle to a stop, and then allow the engine to idle with the transmission in Drive (in Neutral for M/T) for 15 seconds.
4. Then accelerate at moderate throttle to 50 mph and maintain that speed for 15 seconds. Bring the vehicle to a stop, and then accelerate to 40 mph and maintain that speed for 15 seconds. Bring the vehicle to a stop and allow the engine to idle for 15 seconds. Repeat this step at least 5 times.
5. Check for any Pending codes in the Generic OBD II section of the Scan Tool. If no Pending codes are set, the Component Monitor test is complete. If any Pending codes are set, refer to the appropriate trouble code repair information to make the repair.

check to make sure nor of you vaccum line is not loose and all your clamps are tighten sound line a line is off the system and your intake is not tighten properly

if it is a 4 cyl you will find it under the intake manifold in front of the radiator. if 6 cyl it also may be on the front side of the engine just between the engine and transmission.

Disconnect battery or pull the memory fuse for the radio. If you enter the wrong code 3 times on the radio it reads error and locks up.

A thing called the "Clock Spring" in the steering wheel needs replacing. It has all the wires in that operate that stuff on the steering wheel and airbag. There may also be a sliding ground connection that could be bad or dirty.
