Here is a very complete trouble fault table, where you may find the answer.

SOUND LIKE FUEL GAUGE IS FAULTY.IF YOU REPLACED FUEL PUMP ASSEMBLY WITH NEW FUEL LEVEL SENDING UNIT.PROBLEM IS IN THE GAUGES.

Trouble Code: P1336 CKP Sensor System Variation Not Learned Possible Causes: Set the parking brake and block the drive wheels for safety. Verify the hood is closed. Read the trouble codes. If a code is set, refer to that code. Start the engine. Allow engine temperature to reach at least 158?F (70?C). Then key off. Select Crankshaft Position Variation Learn procedure on Scan Tool & start the vehicle. Apply the brake pedal firmly and verify the selector is in Park. Increase accelerator pedal position until fuel cutoff is reached at the test rpm (e.g., 5150). Quickly release the accelerator pedal after fuel cutoff is reached. The CKP system variation compensating values are learned when the engine speed (rpm) decreases back to idle speed and the procedure terminates. Read the trouble codes and recheck for DTC P1336. If DTC P1336 runs and passes, the CKP system variation "learn" procedure is complete. If not, look for other codes. If no codes are set, repeat the test procedure.

See if you can find a box terminal or something that they have in common. If they are connected to a bus-bar or in a terminal box it is possible that they have gotten dirty or oxidized and all connected together. It has to be something that they all hook to. Good Luck!Gilllight

That would be a shop manual - try Ebay for a used book.

It just bolts to the body, easy

There is not simple fix I am aware of, this almost always means the transmission has failed.

it should be on the fuel rail itself. with a vacuum hose coming out the top of it. befor you replace it make sure the wiring harness for the injectors is plugged into the main harness

po785 is a shift/timing solenoid malfunction. po340 is a camshift position sensor A-Bank 1 circuit malfunction.

One thing to check into would be the antitheft system. Not knowing what year or type of vehicle makes it hard to help. But like i said, engine shut down in 5 seconds or less is a symptom of a bad antitheft security system. This link explains.http://vatspasslockpasskeysecurityhelp.yolasite.com/

Are they stuck on lock? Maybe you have a switch stuck or shorted out? Please rate my answer so I get points for it.

Call a locksmith, if you try to break in you will most likely do more damage than good and end up costing more than getting a pro to open it for you. This advice comes from 45 years of work experiences.

Step 1: Confirm the heater core is leaking.Step 2: Take it to a mechanic.Step 3: Pay the man for his good work.Step 4: Rejoice in that you did not have to depend on this website for help.

If the steering wheel is shaking when you apply the brakes, this is usually caused by the front rotors being warped, you can either replace the rotors (replace front brake pads as well) or if they measure thick enough, they may be able to be machined to recover a smooth - non warped surface again. Your local Auto Zone, Advance Auto Parts, or any other parts place usually can machine the rotors for you at a resonable price, but sometimes it is better to just replace them.... the thinner the get machined the less heat they will disapate and could possibly warp again after a few thousand miles.

Hope this helps

Check if the car starts when you jump start it. If it does try to remove the jumper cable and the negative of the battery. If the car dies then it is a weak alternator. If it keeps on running it is likely a weak battery. If jump starting does not work you can be sure that it could be electrical or the fuel delivery is an issue.

Check also if all cylinders has sparks by pulling out the high tension cables from the spark plugs one at a time. Make sure you have gloves and you keep the end of the cable over the motor. There may be one that is weaker than the other. It could be a bad cable or wire.

Have the fuel pressure at the injector tested. The pressure may be low due to dirt or faulty injectors.

Hello

The 6 flashes are not an Airbag fault code ...the flashes are only to alert the driver that a fault exists, in other words to get your attention to a failure of the SRS (supplemental restraint system) system - You will now need the system scanned with a special scanner that can read the codes in the Airbag/SRS system. This is not a generic scanner, it is a special tool, most repair shops will have one or of course the dealer. And any AIRBAG system fault shuts down the system, so if you get in an accident you will have no Airbag deployment.
