Re: kawasaki ninja ex250 won't start
The petcock is vacuum operated, there should be a small hose just behind the larger fuel hose thats attached to the petcock. What it does is when the bike is cranking over it sends vacuum though this hose and operates a diaphram in the petcock causing fuel to be released in the fuel line. This is for people that don't turn the fuel off as far as I know. Anyway if you take the small line off and get another piece that fits there and turn the petcock on and **** on the small hose it should send fuel out the bigger fuel hose if it works correctly.

Hi Zac first thing i would check is fuel pressure. remove fuel hose to fuel rail hold hose into container get some one to crank motor only for a few seconds and turn ignition off..if no fuel ! suspect; fuel pump . also listen for fuel pump to hum when turning ignition on it should make some noise! hope this gives you something to check. as a mechanic i have come across this as a problem before.
First thing I would do is charge up the battery, and check base fuel pressure with a gauge. Using starting fluid is going to be tough - its the large black hose in front of the master cylinder which is tough to get to. If it cranks over fast enough, and has fuel pressure and spark, it should start without any help.
not sure what you said but. seems the battery is discharging,? 12.6v is fully charged, own a voltmeter? try a good loaned battery , does it start the car,? i think you meant? i can jumper cable start my car at any time. (off another running car) but after running my car, the battery discharges and it will not crank at all. right? this means ,the charging system on your car is bad. if the starter cranks great, then the engine is flooded or is in great need of a tune up (sparkplugs etc) if flooded try the super secret in the op guide, crank with throttle wide open , this magic trick cuts all fuel injection allowing the flooding to purge away, and eventual starting. my guess 2 is the car wont start, so you crank the battery flat you jumper start it and it runs. (luck) then day 2, same deal cranks ok but wont start.. ever tune up the engine?
Spray a little starting fluid in it there and try to get it to fire up and then get on the throttle to blow out anything from the carbs. Take care and good luck with this as i am not a bike service guy i just feel bad for anyone who is working on bikes as there frustrating as you know what. LOL good luck!!
It sure could be. But, first...by "won't turn over" you do mean it cranks at normal speed but won't start? A simple test of the fuel pump is to stand by tank and listen as someone turns key to on. When first turned to on, your pump will activate for 2 or 3 seconds, pressurizing the fuel system, and then shut off if the engine computer doesn't get a cranking signal. Do you hear it come on? If not, then something's not turning your pump on. If you can hear it buzz on briefly, then maybe it's your filter. Another test: Spray a little starting fluid into your intake manifold (remove the big hose going into intake manifold) while someone tries starting it.If it doesn't fire and try to stay running, then it's probably an ignition problem. But if it does fire off, then you know it's a fuel problem-likely your pump or filter. good luck.
Check your battery and alternator connections for tightness. Does it crank over, but won't start? If it won't even crank over, then likely some connection did come loose, like an alternator connection, possibly your fusible link (near the battery).
If it does crank, but won;t start: You'll just have to start from scratch to find the problem. Try to determine if it's fuel or ignition-related. Check for spark at a plug wire. If you have spark, then ignition is not the problem. Check if your fuel pump works. When you turn key on, you should hear the pump buzz on for a couple of seconds. It should also be on when cranking and running, but you can only hear it, or should, when you first turn key to on. If your toyota has a schrader valve on the fuel rail (a valve for checking pressure-it looks like a typical air valve, like on your tire, but is for attaching a fuel pressure gauge) if it has one punch the center with a little screwdriver-gas should shoot out if you have any fuel pressure, If not, have your fuel pressure checked.good luck.
Do you notice crank when you turn over the key in ignition to start.
Does it turn over but does not start, or no start nothing at all.
If its not cranking and nothing happens when you turn the key, then its battery and starter related problem, both needs to be inspected.Either battery is not completely charged or its weak battery,that is not holding charge or its faulty battery or its connections are loose.--------
BUT if it is cranking and not starting, this clears that battery has juice in it and battery is doing its job and other possibilities needs to be checked.
The other possibilities are ,is the fuel pump coming on when you turn the key to start,is the spark is noticed at spark plug, is the check engine light coming ON.
