Car Starting Problems

If you follow the positive battery cable it will lead you right to the starter. Mark

vacuum leak

Blown fuse or defective fuel pump relay.

Presumably you mean slow cranking. Check for weak battery or bad starter.

If not slow cranking so much as long cranking time check for loss of fuel pressure overnight using fuel pressure gauge. If so, suspect leaking injector or possibly leaking regulator.

92 octane is recommended

The relay is a device that typically uses low amperage 12 vdc electrical (control voltage) to switch a much higher amperage circuit (load voltage). In the case of an ignition relay, the key/ignition switch is not capable of handling the high amperage requirements of the engine components electrical draw, so a relay is run in the circuit and controlled with the keyswitch. The relay has an electromagnet (control) and a switch (load) inside, and the electromagnet moves the switch when the control is energized. You do not ALWAYS have to have a burned fuse to have a bad relay, the contacts on the switch can burn, or the wire in the electromagnet can open, both resulting in a non-functioning relay.

check the battery,check the starter, see if their both good. It's the battery, if all it does is click. The clicking is the starter trying to start but not having enough electricity.

check starter bendix gear or flyweel missing teeth, make sure engine is physically turning it may just sound like it from starter noise,other then that need a Little more info good luck

Check your fuel pump and/or fuel pump relays

Some cars have a fuel cut-off switch that upon an impact kills power to the fuel pump. From my experience it doesn't take much of an impact to trigger this switch. Most vehiles with this feature have a reset switch located inthe trunk area.

There are a number of reasons.

It is not painted, or covered by a corrosion resistant material, as the height temperatures it is exposed to would tend to burn-off or other wise remove such coatings.

The exhaust gases passing thought it contain corrosive substances such as sulphur oxides (Sulphuric acid) Nitrogen Oxides (Nitric acid) to name a few. Even the use of corrosion resistant coating may not be enough to protect against these, given that chemical reactions are improved with heat (IE the hotter it is, the faster it goes), and exhausts are hot.

Also, one of the products of combustion is water, and water rusts iron/steal, even in the absence of acids.

Other metals could be used, but the additional costs of using stainless steel, or perhaps aluminum, are (one must assume) currently not seen as beneficial by purchasers.

It should also be noted that over time the "sound absorbent" material within the exhaust, normally glass fibre, becomes impregnated with carbon. This means that an exhaust that wound last for ever would still need to be replaced eventually, as is would lose it's sound absorbing properties.

If the 2004 Nissan Maxima won't start and won't come out of Park, one thing to do would be to try moving the steering wheel back and forth while trying to move the gear shift out of Park. If this does not work, the thing to do might be to reprogram the key. Some car keys have a computer chip in them to prevent theft.

The starter is either jammed in the open position and is already engaged in the flywheel and won't retract, or the motor is just plain burned out. You will have to pull it and take it to Auto Zone where they will test it for free for you. You can pull it and test it yourself by grounding it and applying power with a FAT HEAVY INSULATED cable and see if the end flies out, but it could do so out of the car but not have the strength to do it under load. It's probably shot, sorry to say. Phil

Either car can he damaged if the cables are shorted out or reversed. If hooked up properly, damage is very unlikely.

Charge or replace the battery.

An engine needs three things to start: 1. fuel; the engine must have the proper amount of fuel delivered to the cylinders. 2. ignition; the engine must have an adequately strong spark at the spark plugs, delivered at the right time. 3. compression; an air/fuel mixture must be drawn into the cylinders then compressed as the piston rises to the top of the compression cycle. If all three conditions are met as the engine is turned (either by the starter or by "push start") the engine MUST run. To discover why the engine won't start, you need to find out which of the above is not taking place or not taking place properly. Insufficient or too much fuel can certainly cause an engine to not start. A non-existant weak or improperly timed ignition spark can certainly cause an engine to not start. Low on non-existant compression cancertainly cause an engine to not start. If you suspect that there is no or insufficient fuel, I always recommend that people try a little starting fluid. One common problem this time of year is "condensate" in the fuel line. If a few drops of water condensate builds up in a line, then the line freezes, no fuel will get past and your engine won't start. It's always a good idea to use a can of fuel line de-icer once or twice through the winter. Typically, if there is a problem with the ignition system, modern automobile computers will report a "fault" by flashing the "check engine" light. If that's going on, use a code scanner to find out what's wrong. All you can do is start to narrow down the problem, isolating different "sub-systems" to see what's keeping the engine from running.

Could be your alternator problem.

Assuming you mean fuel PUMP relay, it is the remote switch that turns the fuel pump on and off. If it fails, your engine will not run.

yes

If the voltage level of the battery is low, turning the key to "Start" can cause a further voltage drop and you'll hear the click. Sometimes the low voltage condition will be such that the starter is engaged, drops voltage below a threshold, the solenoid disengages because of low voltage condition then the voltage comes back up enough to re-engage the solenoid and it clicks again. In either case, if you have a volt-meter check the voltage of the battery while someone attempts to start the engine. If the voltage stays anywhere near 12 Volts, check both battery terminal connections. If either is dirty you may just need to clean the contacts. If the battery voltage is down near 7 or 8 Volts when you try to start the vehicle your battery voltage is too low to do much good. The battery COULD be bad or the alternator may just not be charging. Don't just replace the battery until you are able to determine if it's a battery or alternator problem. With the same volt meter, check the battery voltage when the engine is running. The alternator SHOULD bring the battery voltage up to 13.5 volts (or near enough) and if it doesn't, you probably have a charging problem. In either case, have a reputable parts store, like Checker Auto, Kragen Auto, Auto Zone or Pep Boys check the charging system and the battery to find out what's wrong. In some cases the starter can be faulty and drawing too much current but they can check that too.

Check fuel filter and carburetor or fuel injectors if so equipped. Some older cars with Carburetors have a fuel filter where the fuel line enters the Carb. Provide year and engine specifics for a better answer.

Sounds like fuel flow is limited. Check the fuel filter. This is a cheap replacement, and needs to be done every 50 to 100K miles anyway. If this doesn't help, check the fuel pump. If this doesn't help, look for obstructions to the exhaust. You see this in older cars where the exhaust system is not stainless steel.
