SOURCE: brake warning light is on for 2002 bmw 745i.

The brake pads have sensors in them, when the pads get worn down to the sensor the light comes on letting you know its time to replace. this happens well before the pads are completely gone to reduce wear on the rotors. You should have the brakes replaced and the sensor also.

SOURCE: Car starts then immediately idles down and shuts off

i have had the same problem at times. my car would start and then shut off. but i found that i needed oil and check my oil and it was a quater low put in some oil and everything went fine i notices that everytime the oil is low the same thing happens also depending on the position of the car being park meaning that if you are in a down hill position or up hill position i will do the same. so you have to accelarate for 1 minute to have the oil go up. i hope this works

SOURCE: 92 GMC Jimmy Replaced fuel pressure and fuel

if you say you replaced the fuel pressure ? "regulator or pump" that was not very clear as to which so i am guessing and the filter but have no fuel to the fuel bar valve either you have no power to the pump or a clogged fuel line or a blown fuse or a short in the power suppluy to the fuel pump if you turn the key to on position without cranking it do you hear a slight humming noise if so the fuel pump is working ..if you do now hear this chances are as i stated above
the use of a test light is required to check for power to the pump as wel do you smell any gas =fuel lines are rotted .let ne know what you discover and check all your fuses

Engine is cranking? Check if the fuel pump is working, fuel pressure right and injectors. Check starter and solenoid. Also ignition switch. If all this its OK, then go to sparkplug, coils.

Keep us updated.

When i driving bmw e36 1995 , suddenly the engine shake and broke down, and then i could not start again.Then i check fuel pressure, it's still good but not ignition in spark plug.please help me in this...


This is likely a crankshaft position sensor. This would cause no spark and no injector pulse. You would still be able to crank it and have great fuel pressure. This sensor is located behind the crank shaft pulley and is responsible for sending a signal to the computer to pulse the ignition and the injectors. Let me know if you need anything else.

Bmw 530d e39 2002 car will not start, turns over fine but will not fire, bit of easy start and starts after about 5 - 10 sec cranking, once running, engine runs smooth and powerful, as soon as you turn it...


Most probably its a low fuel pressure related problem.Get the fuel pressure checked.If its low then this is faulty fuel pump and clogged fuel filter issue.the other possibilities are,-----

A car that cranks over but doesn't start, in many cases will be due to a bad fuel pump, a broken timing belt, an inoperative cam sensor or crank sensor. Also this problems are related to faulty spark plug. Check the spark at spark plugs when you start the car. Do you notice any spark. Actually you should see. If in case there is no spark then it's a spark plug problem. Also the coil pack gives power to spark plug. So check the voltage at coil pack. It will show 12 volt.If there is no voltage noticed at coil pack then its faulty coil pack that has to be replaced.If all the possible options checked out ok then check the car starter. The starter gets power from battery to start the care. If the starter is faulty then it will not let the car to start. Also check and confirm that there is fuel in the car. If it very low fuel then in some cases this causes the problem. Also check and confirm that fuel pump is functioning properly and the fuel filter is not clogged. One of the easiest ways to check for a fuel pump related problem is to spray a little starting fluid into the air intake while trying to start the car. If the car starts momentarily, then there's a good chance the fuel pump is not working or the car is out of gas. You can also listen for the fuel pump's humming sound when the key is first turned on. Also if a inoperative fuel pump is suspected, a good technician will always check to verify there is power and ground being supplied to the pump, to eliminate the possibility of a bad relay or electrical issue. Fuel pressure can be checked with a pressure gage and if there is pressure, pulse can be checked at the fuel injectors in several ways including the most common, with the use of noid lights. If the injectors don't have pulse the engine won't start. ---------- This troubleshooting tips will help you to solve the problem.Thanks.Helpmech.

Have 2000 BMW 328ci. When trying to start it wants to turn over and almost starts, but sounds like it not getting fuel? What can I check?


You should be able to cycle the key to pressurize the fuel rail. There is a little tire-valve looking thing on the fuel rail that you can burp to see if you have fuel pressure.

You can also check for spark with a commercial spark testing tool or the classic hand method of taking a screwdrivver and placing it in the spark plug boot and laying the driver on top the motor near something metal/grounded. Crank her and see if you have a spark jumping to ground.

Then when you know you have spark and fuel you can start considering other issues....perhaps have the ecu read for possible trouble codes.

1997 bmw 328i not starting


Come on give us more information. Think if you were trying to fix your own problem and you had to explain the problem to someone else with exactly no knowledge of what's going on.

1st off....a key with bad electronics and reader will open the door and that's it.

So that being said does the key turn the engine? If so the key, the program and ecu are ok. Say the engine cranks but doesn't start. Fuel pump. unscrew the access plug on the fuel rail and see if any fuel squirts out. NO......don't ever do this when it's hot..........not that yours is because it doesn't run but I had to say that. The millisecond you turn your key over to get it to try to start...the fuel pump comes on and pressurizes the entire fuel system.

Got fuel pressure, the engine turns but still no start= ignition spark plug engine computer problems.

1992 BMW won't stay turned on


The spark plugs shouldn't be wet, or are they wet because it won't start and they just get fuel soaked? Check the injectors.
