Car will not start


If the the car cranks and won't start it could be many things. Fuel pump is likely. If the timing belt is broken you would hear sounds from inside the engine you really don't want to hear. If you have more than 60K miles on a timing belt, it's good you replace it anyway and do the water pump, oil seal, and tension pulleys at the same time to save yourself some money.

Your hearing lifter noise common in most cars in cold weather I have a 2001 sc1 same engine as yours here's how to get rid of that ticking sound go buy a quart of Lucas synthetic motor treatment change your oil and leave it 1 quart low add the Lucas synthetic oil stabilizer within 1 week you will not hear the noise agian reason your hearing the noise is there's no oil at the top of the engine on a cold start oil when cold is thicker hints why your noise in your engine what Lucas does is eliminate the dry start by the way my engine has 288,000 and does not use a drop of oil after you use this product you should use it every oil change you will see your car will thank you regards Chris

I have a Honda Accord 2004 with a code PO339, PO113 &PO344. can you assist in advice to solve these problems


p0339 is crank shaft position sensor related error. you need to be sure that its wiring is not damaged and it is not shorted somehow. if it is broken or getting broken, car may stall, or wont start att all.

p0113 is for intake air tempoerature sensor errors. that sensor measures air ehich enters the engine. it is least important. its effect may not be noticable when weather is not extremely cold.

p0334 is for knock sensor on engine. it prevent predetonation due to ignition conditions appear. it is felt when engine is under load like climbing, and engine speed is low. check for wires if it is ok replace sensor.

we can tell that temperature sensor is not directly effects other sensors.
but knock sensor and crank position sensor is to important for engine. if you have no starting issues, even cold or warm engine, invest on knock sensor first.

When it is below frezzing my Isuzu makes a clicking sound instead of starkting but in warm weather it starts all the time ?


more then likely the battery is going bad. in cold weather it takes a good (cca) cold cranking amps, battery to turn engine over. but in warm weather the engine is not as cold and therefore needs less cranking amps. thats why you hear clicking when trying to start car in cold. it is the solinoid clicking and not enough power for starter to turn it over.

Why would my oil press. be 3/4 up on guage all the time.cold starting little knoise fo 30 sec.


The weather you live in, oil weight being used, what type of car/truck. I'm thinking run an engine cleaner through for 5 min to clean the engine. What you are hearing is most likely a sticky valve. Drain the oil, change the filter and fill with a light oil in the cold with light loads and heavier oil in hot weather. A multi viscosity oil can be used to weigh out the cold and hot weather.
