Question about 2002 Hyundai Elantra GLS

1 Answer

Why doesn't 2002 Hyundai Elantra GLS not start right up when cranking?

I have been having an issue with my car starting right up for months. I know it is time to get rid of my car but I just need to keep her running a little while longer. What I have already replaced: Fuel pump and filter air filer oil gasket both converters new gas cap spark plugs/wires and coil pack Purge Valve Camshaft sensor fuel injector 3 Now I believe that is all. I have a check valve but I was having some difficulties installing that right now. SO back to issue is my car cranks but doesn't turn over. I usually have to crank two times sometimes three or more. Now that it is getting cold outside I can usually start my car on one crank first thing in the morning when it is COLD but that's it. I am trying to decide if I should try a crankshaft sensor or a start relay fuse and where they are located. This problem is terribly embarrassing and it sucks my gas mileage up. ALso when I changed my Purge valve I didn't hook my vaccum hose back up correctly. It took me a day or so to realize that I hadn't put one end into the valve that connects behind the engine and that resulted in my brake pedal being VERY HARD. I have since hooked it back up properly but my brakes have not gone back normal. Now, I was in need of new brakes that was going to be my next project, but now I am not sure if I need brake pads or everything or where to start.

Wow. Any codes in the ECM? Is the engine light on? The crank shaft position sensor could cause this but the other stuff you replaced probably wouldn't. The start relay and fuse are just to turn the starter so if the engine is actually cranking over but not starting then this is probably fine. After all you have put in it you should have just took it to a shop and had them diagnos it. Did you yet?

SOURCE: 1991 hyundai scoupe; engine cranks but does not

You stated the 'CHECK ENGINE' light came 'ON'!... what/which DTC'S (Diagnostic Trouble Codes) OBDI were retrieved? In 1991, OBDI (1) was used. You could retrieve codes by either turning the ignition switch on/off two or three time within 3 seconds and the light would flash for each number (this way you could determine which system was affected). The POSSIBLE CAUSES are many:

Crank Position Sensor
Ignition Coils/Wires
Water/contaminated fuel
Electrical (Relay(s), fuse(s), Poor ground connections, failed ECU (Engine Control Unit), etc.

Are you getting a SPARK to the plugs?... if so, check fuel pump pressure
If you're not getting a spark to the plugs or not getting a fuel injector PULSE, then the crank position sensor MIGHT BE the problem.... NOT SURE!

Too many POSSIBLE or PROBABLE causes.

In order for an engine to RUN, it needs these things:

1. Air flow (intake AND exhaust)
2. Fuel (proper fuel to air mixture)
3. Compression (140 to 2?? psi)
4. Proper Timing (not too advanced/retarded)
5. Ignition (sufficient and at the correct/right time)

Now, after listing these 5 things, without CHECKING each one, your guess is a good as mine.

SOURCE: 2004 Hyundai Terracan, 2.5 turbo diesel, manual.

right renew the glow plug timer/relay if you put a meter on the glow plugs when cold and turn ign on (with help) it should supply power for a about 20 secs ,time depends on outside air temperature ,if all else fails then do a colin --- use a push button switch,wired to a relay so glow plugs can be operated by pushing the switch which you will mount on the dash ,cant beat a manual overide system

SOURCE: 2002 hyundai elantra cranks but doesn't start

the fuel pump will only run a few seconds after turning the key on,if the engine does not start it will not run to avoid flooding. to avoid electric shook, make a test tool, two large alligator clips and about 8" of wire .get a new or old spark plug and put one clip around the large mettal porttion of the plug and ground the other to something positively metal on the engine. while someone turns the key to start the car not playing with the gas pedal, see if you have a good spark.if not you must find out why.you where correct looking at the timing belt. it must turn you must have spark and you must have gas.you cannot see the gas,you would need to test fuel pump preesure,and checkat least one injector wire with a noid light to see if it flashes indicating current to the injector. if you have spark you could try spraying a small amount of carb cleaner into the intake after removing the intake hose from the throttle body,do not use starter fluid.if it acts like it will run or does run for a short time it is definately a fuel problem.

I have a 1997 Hyundai elantra gls..it cranks but wont start sometimes, i usually have to accelarate (give it gas)for it to start and there was misfire on the spark plugs, what gives?


Fist off no amount of giving gas to a fuel injected system helps it start. What you are describing sounds like the crank shaft sensor is bad. That would cause misfire and then no start later.
