check for fuel pump shut off switch to reset

My first guess would be a faulty injector. Are any of the spark plugs wet with fuel ?

turns slow when starting??? check battery voltage and cca (cold cranking amps) if you are on original battery (possible) you most likely need a battery. other than this info is not sufficient to give any other recomidation

reset code

CHECK PLUGS

Hi rowdy the problem need to involve a scanner. Check the readings KOEO of the coolant and the the o2 sensor write them down. Reinstall the old sensors back check the reading write them down. Comparing the reading. Start the vehicle if it start let it run for the engine to get his normal temperature. Check the reading KOER. If the reading stay the same check the wire from the sensor to the pcm for.short to ground or open or short together. If there is no short to ground no short together no open the pcm need to.change.

test the following and fix it. GOD BLESS you.If nothing happens when you turn the ignition key to the "Start" position, it means that the starter motor doesn't turn over the engine. Most commonly this could be caused by a dead battery; If the battery checks out OK, but the starter still won't crank, there could be a number of possible reasons. Here are some of them: • The ignition switch could be bad - it's a common problem. An ignition switch is an electrical switch installed at the back of the ignition lock mechanism. If jiggling the key in the ignition helps start the car, the ignition switch should be checked first. • The starter solenoid control wire could have a bad connection. • The starter motor itself or a starter solenoid could be bad. • A neutral safety switch is bad. If a car doesn't start with the transmission in Park, but starts in Neutral, it could be caused by a problem with a neutral safety switch. . • A problem with vehicle's security system or some other electronic control module (e.g., ECM, BCM) may also prevent the starter from operating.

what is your question?

Code 340 is for a problem with the cam sensor circuit. I doubt it would involve the gas tank. May be a coincidence.

Sounds like your heater core is bad and is leaking. Do you smell coolant inside the car? The reason your temp goes up and down is there is a air pocket developing for the missing coolant and its struggles to keep the flow through the system properly

Bad earth

Could be a fuel pump failureYou don't always get a code for everyvehicle problemTakes some old school thinking & testingto find these issues

it sound to me like the lighter plug itself is loose and when you released the parking brake wiggled the plug enough to short out and blow the fuse . check to see if the plug is loose .

It is an interference engine, time to remove cylinder head and rebuild top end!

could be crankshaft sensor.

Usually the shops don't actually fix a thingThey just put it back together & send youon your way, without installing new parts& doing the job correctly

Sounds like a possible water pump problem with the over heating part. About the heater only blowing cold you may have to get it "recharged"

test the horn by running a live wire to the live terminal on the horn if this works you need a new unit , othrwise have you checked fuses,

Whats the problem? The drum got hot and warped or the emergency brake is froze. Rap the drum with a BFH until it comes loose. What you got to loose. You've done breaks before. Is the a slot where you can loosen the self adjuster inside? Otherwise use the BFH.

The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type. Also engine mechanical problems ca cause many drive-ability related problem such as rough idle and other symptoms
