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.

My 97 Chevy blazer won't start I hear the fuel


Bad fuel pump, fuel filter, it may not have enough pressure or you aren't getting spark

97 mercury mountaineer. won't start


hi,

watch your oil pressure when cranking, you have to have some oil pressure to get the fuel system to start. you may have to find the hot wire at the relay and energize it to see if it is indeed the fuel pump going out. if its been sitting and its a 97 the fuel pump just might have went, you can also try hitting the gas tank from the outside in the middle to see if that works too. have a water hose or fire extinguisher around when your working on fuel system and leave one of your battery cable a little loose..

My suburban just stop while i was driving


And what does it do now? Does it crank over and not start, or just no power anywhere? If nothing, no power, recheck your battery connections, grounds, for something jarring loose, maybe a relay in the power distribution center (by your battery) jumped out of its socket. Gotta check around...But if it cranks over, but won't start, you need to review the basics for this condition: needs fuel and spark to run. Are you getting fuel up to the engine? Can you hear the fuel pump buzz on for 2 seconds when you turn key on? That 2 seconds is to pressurize the fuel line. When you start cranking, your pump will come on again, and stay on when engine is running. You can only HEAR the pump when someone turns key to on, and you stand or squat near the tank to listen for it, maybe with tank fill cap removed. If you cant hear the pump your FP relay would be the next place to look for a problem of no power to pump. If pump IS working, then back to engine: check if ignition (spark ) is working. Easiest way: pull spark plug wire, remove plug and put it on the wire you pulled off. Ground the threads of plug on metal of engine, have someone crank it, and watch for spark at that plug. If no spark, check another wire with same plug. No spark means you need to diagnose your ignition starting circuit. Among other things, this involves checking for power to coils, power to the computer (your check engine light DOES come on when key on, right?), a lot of things that a diagnostic flow-chart covers to pinpoint the problem. A good repair manual could walk you through it, if you have a multimeter. If not, you may need someone to help you. If you DO have both spark and fuel up to engine, it's simplified some, but still problematic. Crank position sensor? injector circuit? Good luck, M>, and don't give up.

My car sat idle for about a month but I had a friend start it occasionally to keep the battery up and running. One day the engine would not turn over when he tried to start it up. The lights come on like...


yeah, try starter fluid just to verify if it;s fuel or spark related. If it starts or tries to, then it's a fuel problem. You should be able to hear your pump turn on, when you turn key on, may need to stand by tank, when someone turns key on. it should activate for about 2 seconds, with key on.(that's to pressurize your system with gas) then when cranking, the pump should run(may not hear it then-so just listen when key is initially turned on. No noise: your pump may not be working. If you can hear the pump, it may be another issue.

My car was running fine yesterday and this morning it didn't start. got a new battery, replaced the oil and checked the fuses. everything is fine but car still won't start. suggestions, please


Check for spark and fuel. When you turn the key on you should hear the fuel pump in the tank for a few seconds till the pressure builds up. When you crank the engine there should be spark at the plugs.

2000 Eclipse GT turns over but doesn't start. Fires once in a while but won't run. Had timing belt replaced.


Hi, if the car turn over, and it don't start. Then it is like the engine don't get fuel. Or bad a spark plugs. Most common problem is the fuel pump going bad.

It could also be a bad fuse, but a easy way to check if the fuel pump is ok is to have someone stand at the back of the car when you turn the ignition. The fuel pump should make a buzzing sound for a few seconds. And if you don't start the car right away the fuel pump will stop.

If you don't hear any buzzing from the fuel pump/fuel tank then you have a bad fuel pump............

Lancer cut out while driving. will turn over but will not start. it has fuel but no spark.


check mass air flow sensor or crank sensor. If those are not working then the car won't run. is there a check engine light on or a battery light on? obtain an obd2 scanner from an auto parts store and download the code. that will usually tell you everything you need to know. also, check to make sure youre actually getting fuel to the engine. you might have a weak fuel pump. prime the fuel pump a few times before trying to start the car by turning/cycling the key from off to on, not start*, in 2 second intervals a few times then try to start the car. you might be able to hear the pump running under the back seat.

hope this helps!

2004 Kia Sedona wont start but i can hear starter.


if the starter is revving very slowly it is the battery, charge battery. if not, It can be three things happing. 1 no spark 2 no fuel 3 no crank signal or the car computer is bad- you will need to unplug one of the spark wires and remove the spark plug and put the spark plug in the spark plug wire boot, and touch the spark plug on any metal on the car and have some start the car. donot touch the spark plug itself and see if there is a spark. if spark is bright, then it is not spark plug and wires but if no or spark is not bright, check the spark plug wires by applying a little bit of water on the spark plug wire and take a 12v test light, connect the clap to ground and and have some one to crank the vehicle, touch allover the spark plug wires with the tip of the test light, if you see spark, replace the wires and change the plugs.. they are not good. if spark is present, check for fuel by removing any one of the spark plugs and see if it is wet. if wet fuel pump is ok but if not go look for the fuel pump fuse and relay. is fuse blown, replace, check the relay resistor with a volt meter. it should be around 40 to 80 ohm. if everything is good from this point check the fuel pump itself by disconnecting the connector to the pump and apply 12v and ground using jumper wires or some wires to the fuel pump if you donot hear the pump,replace pump. if you, the crank signal or computer may be the problem
