Car Starting Problems

Yo should be able to hear the pump motor with your ear to the fuel tank filler hole while a helper turns the key on. If you don't hear it, then have him crank the motor. Get a wiring diagram (good luck, online anyway) or probe the wires at the pump and verify +12 volts and - ground are available at the fuel pump connector with key in "Run" or "Start". Check for clogged fuel filter (with the filter removed from the vehicle, you should be able to blow air (with your mouth, not from an air hose) through it with little resistance). Check fuel pressure at the fuel rail with pressure tester.

Also check for spark by unplugging a spark plug wire from the plug and inserting a tester (available cheap at parts store). Verify no "Check Engine" or "Service Engine Soon" lights on dash are not lit. This light indicates a problem with the Engine or Powertrain Control Module, not that the vehicle requires maintenance.

Many other things will cause a no-start condition, including contaminated fuel, faulty ignition system, extremely low compression, timing belt failure,etc.

In order for any gasoline engine to start, you must have ample fuel, spark, compression and correct timing (both ignition and camshaft). If you can't check these yourself, you are better letting a pro do it. You will save time and money by not buying unnecessary parts (sounds like you might have already bought an unneeded pump) or possibly damaging other components.

The relay is bad. When you start it the relay is bypassed when the oil preasure gets over 4 pounds. Replace the relay

will probably be a fuel pump going out. fuel pressure is critcal in a CFI unit. it must have at least 58 psi to start...56 psi= no start

Very likely an alternator problem; if the alt is not working soon the battery would be drained and the truck would shut off.

Make sure battery cables are tight and clean
Check wiring at starter motor
Check wiring at starter solenoid
Check neutral safety or clutch switch
Rap starter with a hammer to see if brushes are not making contact

Turn the ignition on, put your foot on the brake and just shift the auto transmission into the N position. If your battery is totally dead you will have to jump the battery from another vehicle in order to accomplish this.

Yes

By the use of auto transformer and bridge rectifier we can start dc motor.

The very most common problem with all General Motors vehicles is the side post batteries. Corrosion builds up and you do not get a good connection. Remove the negative cable First and Install it last. Clean the battery terminal and the cable ends with a wire brush or a battery cleaning agent. Check the water in the battery. If this does not take care of the problem then you need to have a professional check it out for you.

Possibilities include but are not limited to:

* low battery(possibly caused by a faulty battery, alternator problems or "something" that's draining the battery)

* faulty starter * misaligned or faulty neutral safety switch * faulty keyswitch * poor electrical connection

I have the same problem 1995 Buick riviera SC MINE HAS WOrked great for the past month unlocking it with the remote but today i used the key to unlock it and the security light came on and it would not crank.

using the remote seems to keep it working but using the key is the problem, it triggers the security system and a 15 minute wait.

do you have a remote or are you using the key. ive heard small wires can break in the door locking module and it senses that its being opened with out a key and triggers the antitheft.

Mine has never failed to start using the remote.

hohohohoho

On a 2004 Hyundai Santa Fe, the starter is located on the top of the engine just to the right of the heat protector. To replace it, you have to remove the negative cable on the battery, and then remove the starter cables. Then remove the 2 bolts that hold the starter in place.

make sure your getting fuel to the injectors

make sure your getting spark to your spark plugs and wires or coil overs depending whats on the car

two causes I can think of without more information. You are trying to use a non-VATS key in the ignition of a VATS vehicle. If that's not it, the fuel pressure regulator could be stuck wide open (but it would run for a few seconds). If the key deal is not the problem, put a fuel pressure tester on it, start it and see what the reading on the guage acts like. If it drops to zero (or very low), you've probably got a fuel related problem.

Possibly has an electrical draw from the radio.

Check the terminals in boots are fully snapped on to ends of plugs. Also proper torque on plugs. Remeber if loose, thee is no compression & gases won't fire.

more than likely is the ignition module. What year?

Connect jumper cables from the positive battery post, on your BMW, to the positive battery post on the charged every. Connect the ground together. Allow the battery to charge for a minimum of 10 minutes.

Is it cranking but not firing?

Does it sound like there is rushing air as it cranks?

Both yes.... You blew the head gasket and/or warped the head and now have no compression. :-(

how long does it run before it cuts out? If it runs for about 5 or 10 minutes and won't start again until it is cold it could be the crankshaft position sensor. If it runs for a few minutes, sounds more like a ECT (engine coolant temp) sensor.

The distributor in the Civics has a function of also engaging the coil to create spark. No spark = no fire. Perhaps take a plug out, leave the lead on, hold it with INSULATED pliers against a solid metal part of the engine and get someone to crank the engine over. If the plug sparks - coil and firing switch OK. If no spark, check coil first - remove main + feed lead from coil terminals and check on a meter for power with key on but NO motor cranking. No power = faulty distributor/firing switch.No other ideas sorry! GH
