Have you got access to a star?(merc diagnostic computer)
because that could really help you out.

i don't know how good your mechanical knowledge is but i would check the basics first,have you got fuel or a spark. if i were you i would pop the hood/bonnet, lift off your engine cover and air box with air filters intact and locate your fuel line feed (big silver braided hose) and use a 17mm spanner to open it and detach,be careful of fuel in the lines!!! open it slowly and make sure don't have anything close by that will ignite the raw fuel! with this done push the fuel line over in a safe direction with a collector bottle of some kind on the top and turn your key.you should have fuel coming up through that line in to your bottle,if you don't that rules out loads of possibilities and is probably your fuel pump.

if you don't get fuel coming up,try putting more fuel in your tank before you replace the pump as your fuel gauge may be faulty.you could have checked all this in the same time that it took my to type it out so it's worth giving it a go.best of luck and let me know how you get on

SOURCE: can I change my own front light bulb in 2005 slk350

Yes you can.  The bulb number is a "D2S" if you have the HID (High Intensity Discharge) bulbs.  Most auto parts stores will need to order them but it should only take a day or two.  O'Reilly Auto Parts shows the bulb costing 89.99.  They are very expensive compared to the usual $10 bulbs on regular cars. 
If you don't have the HID bulbs, yours is a halogen bulb.  The bulb number is "H755".  This one is the $10 bulb.
Double check which bulb you need before purchasing one! Most parts stores can tell you which bulb you need just by looking at the car's headlights.

SOURCE: driving car it just quit, will not start back

fuel pump relay behind plastic cover that is behind battery. there are 2 black relays ine is climate control and the other is fuel pump. the climate control will say klima on it. Bridge circuit 30(hot at all times) and circuit 87(consumer) with a fused wire and the vehicle should start if that is the problem. In all honesty it sounds like an ignition problem. I would remove the dist. cap if it is a cis. if it is electronic fuel inj. try wiggling the crank senser harnes and see if it starts. the early lh and hfm cars had major wireharness issues

Dealer only ,encrypted software ,start playing with it and?????? if anything goes wrong then factory immobilisor cuts in and it has to be connected to the internet via factory and it will not be released to start unless the bar code on the spare part box has been read by the operator with the bar code reader thats on the computer .This part is then recognised as the relevant fault code from the diagnostic check and with a genuine part for that fault code the computer releases the factory immobilisor.SO MUCH FOR THE AMERICAN FREEDOM OF INFORMATION ACT

Cranks no start


There is a lot of types of starting fluid. Some is kind of safe....kind of!! Most will destroy your engine!! If you are using starting fluid on a Saturn, you really need to stop. Your fuel pressure could be incorrect. The fuel pump relay could be bad, or a fuse. Your fuel pump may be going out. Listen to your fuel pump when you turn the key to the "run" position before turning the starter over. You shoulh hear a 2 second buzz from the fuel pump. If you don't hear this , you have a fuel pump issue.

Car won' start, battery is ok, antifreeze is low but not out could this be the problem?


No. it wouldn't keep it from starting. If the engine cranks but won't start, probably gas or spark (ignition) related. Do you hear the fuel pump in the tank turn on for a couple of seconds, when turning key to on, not start? If you cannot hear the pump, better check if you are getting gas up to the engine. Maybe the fuel pump quit, or the pump circuit needs looked at. The pump should briefly turn on with key on to pressurize the fuel system-the fuel line and the fuel rail where the injectors are. Then the pump will turn off, and only come back on again when the engine is cranking, and stay on when running.
Correct fuel pressure is important for easy starting, and good engine performance. Have the fuel pressure checked against the specification for your vehicle. If fuel pressure is good, check the ignition system-check for spark.

Van will not start


Can you hear the whine of the fuel pump with key-on, engine-off? You should hear this whine correspond with the fuel pump relay, located in the relay centre under the hood. It should run for about 3 seconds and then turn off. Of course, this is just the first preliminary step to trouble shoot a no-start condition. Checking for fuel, spark and spark at the right time, are always the first things to be certain of, before you can go any further. Just a note: GM products will only cycle the fuel pump once for every key-on, engine-off cycle. You will need to crank the engine and then turn off the key to reset the pump relay.

The car wont start whe have already recharged and tryed to start and it still wont start the lights come on on the dash but it dosent do anything


This is a generic answer: Assuming that the engine starter turns and cranks the engine; it could be a fuel system related issue. Start by looking into these areas: fuel filter / fuel pump / injectors. Check for open / blown / missing fuses, and if it has been in an accident, some models have an "inertia switch" that is designed to cut power to the fuel pump after being bumped hard. You'll have to locate it and reset it if it has been tripped. Many cars with electric fuel pumps run when the key is inserted and turned to the run position. If you have someone crouch down near the gas tank when you first turn the key from off to run, they might be able to hear the pump run. It will run for a few seconds and shut off - unless the key is turned to start and the engine is runs.

I ran out of gas then i put gas in the car .now it want start .1996 camaro v6 3800 rs


You may have to "cycle" the ignition switch a few times to get fuel up to the fuel rails. Make sure the battery is fully charged. Turn the ignition switch to the RUN position (do not start yet). Listen to see if you can hear the fuel pump running. If you can hear it, turn the key of and wait about 15 seconds and turn the key to the RUN position again. Repeat this step one more time, the turn the ignition to START.

If you cannot hear the fuel pump running when you turn the key on, then you most likely lost your fuel pump when you ran out of gas. This is pretty common - especially if the fuel pump has a lot of miles on it. If this is the case, then you will have to replace your fuel pump.

Have a 2005 chevy colorado, ran it out of gas and now after fueling it it won't start. when you turn the key i don't hear the fuel pump. is there a fuse or a switch to push to reset it?


I would start by replacing the fuel filter. And if that doesn't work ? listen for the fuel pump when you turn the key on. If you don't hear the fuel pump go on when the ignition is set to on (Just before turing the engine over) ? Check the relay or the fuse. Its not ever a good idea to run any vehicle low on fuel. Could cause a number of problems. but it sounds like fuel filter got clogged and sucked up all the junk at the bottom of the tank.

How to change fuel filter on 2005 nissan armada


I would start by pulling the fuel pump fuse and starting the vehicle. This will get rid of the pressure on the fuel line. Once the vehicle will not start crank it over for about 10-15 seconds. Then the fuel filter is located under the brake booster on the drivers side. It has two hose clamps that hold it on. Remove the two hose clamps and replace the filter. Then install the fuel pump fuse. Turn the key to the on position and wait till you hear the fuel pump shut off. Turn the key off and repeat this step 3 times to build fuel pressure. Then you should be ready to go!

Wont start, checked the fuse, cant seem to locate fuel filter.


Turn the key to the ON position without starting the car
You should hear the fuel pump running for 5 seconds to prime the fuel up to the engine so it can start. If no sound is coming from the fuel tank area which can be heard with the drivers door opened in a quite area the oil sending unit on the engine needs to be looked at. If its bad the fuel pump will not prime. If the oil sending unit is good the fuel pump is at fault instead
Oil pressure to your engine achieves to close the circuit to this switch which the computer senses. When the oil pressure is up to normal standards the PCM shuts that circuit off and turns on the fuel pump relay
