"will not turn over" is not fuel related. IF battery and cables (and connections) are OK, and provided the engine is not seized, it's in the starting circuit. possible starter (or solenoid), ignition switch (or wire to solenoid).

    how did you verify no gas delivery? depress shrader vale in supply line? detach fuel line? does it run if you give it a flammable solution? (spray carb cleaner at throttle body?)

Fuel rail, injectors, of possibly the max fuse in the underhood fuse box that powers the fuel pump. see if you turn the key to accessory if you can hear the fuel pump. and if it is getting fuel test the plugs and wires.

What is wrong if the car won't start? Also if the engine turns over?


Could be several things. A clogged fuel filter, a non-working fuel pump, or a defective crank (angle) sensor, for example.

A defective crank angle sensor will prevent the ECU from knowing when to injecting fuel or make spark so it won't do either! The ECU will store a code if that is the problem.

Check the fuel pressure in the fuel rail. If none, the fuel pump may not run (or the in-line fuel filter is clogged.)

Check for fuel pressure and spark. If the gas is fresh, it ought to start.

My 1993 Honda Accord Ex started acting up, cutting off while driving down the road. Finally it stopped on me one day and so a friend said it was the fuel pump. I went and got some starting fluid and...


I took out the fuel injectors and they looked fairly well after cleaning them off. I have changed the thermostat about 6 months ago so I know that its not sticking or messed up. I have a new distributor, spark plugs, spark plug wires so that not it. I changed the valve cover gasket and the O-rings. I have a fairly new start. I have a new alternator and I changed the belts also for that. I have been in the timing belt area because I had to replace the water pump. Once I changed all of this stuff the car has ran fine for the past year or more. The one thing I have not changed and I know is bad is the head gasket which I have been told is a big job. I don't think that would cause the car not to start though. I also changed the air filter and the fuel filter. I checked the fuel regulator and it seems fine. The last time I tried to start it was 2 days ago and I was spraying starting fluid into the injection system. It would start but very poorly and their was white smoke coming out of the tailpipes and after about four times of cranking and trying to start it also had some backfire. I checked the oil level and it is fine. The transmission is fine. That wouldn't stop the car from starting. their is gas going to the engine cause I check the main fuel line on top of the engine. After reading some other people post I think I will check the O2 sensor and see if that is bad. I would also think that I need to check the catalytic converter. After I check these couple of things I will get back to everyone one what has happened and if it works. I do believe my timing belts are fine but I will check to make sure again since the last time I checked them was when I changed my water pump about 5 months ago. Thanks for the helpful responses.

My Mitsubushi Space Star Car won't Start. What can I try?


spark plugs are deep in the head yet you should get all the the old fuel out first, stale fuel wont ignite and will also clogg fuel filter. you need a mix of atleast 70% new fuel even then its not good for the injecters. If its a manual gearbox a tow start is a quick fix although no go for auto's. cant be much wrong if car was fine when parked, plugs-fuel-filter and possibly fuel pump for sure. If that doesnt fix take plug out put in lead and crank engine to be sure you have spark even just put any plug you know works in lead leaving your plugs in engine just to check for spark y turning over engine looking for spark on plug good spark will be blue but any spark is good.

My 1991 lexus will not start when the ignition is turn with the key. The ingine constantly turns over without starting and preceeds to kill my batterie.


Well if it is cranking you need to see if you are getting spark and fuel.....Try turning the ignition on without cranking the motor....You should hear your fuel pump making a whirring sound for about 3 sec.and then shut off...If no sound from pump (which is located in the fuel tank) check the fuel pump fuse If fuse is good check fuel pump relay...If all checks out ok with fuel pump take into consideration when the fuel filter was changed last....I dont recommend adding fuel injection cleaner to your tank without first changing fuel filter...additive is designed to break up debris thus breaking up all trapped particles in filter sending debris through your injectors.... To check for spark pull the #1 spark plug wire and place it on an angle on tip of plug (allowing you to see if spark is present) have an assistant crank engine while you look for spark..... Do not hold spark plug wire in your hand while engine is cranked.... I hope this has helped you

Slower Cranking And Hard Start-Up When Cold


It could be the manifold air temperature sensor, which wouldn't necessarily through up an error if it's reading incorrectly. This would, in turn make it harder to start if its cold, as it won't supply the car with the extra fuel it needs to start.

Replace fuel pump-stil no start


Was it empty when you parked it? (i.e. did someone drain the tank, and put sugar in it? something like that?) If not... the fuel filter could be clogged. Check that. Most cars of this age are fuel injected, so the fuel at the fuel filter will be under high pressure. Chiltons manuals usually discuss how to de-pressurize the line if needed. But you probably already dealt with this changing the fuel pump. Good to hear it's turning over. After (finding) the filter... check to see if any fuel is making it through the filter. Turn the ignition to "on" and it will likely start the fuel pump and spray fuel everywhere (if you disconnect the filter output.).... besides having a mess, you will know your fuel pump works. (Try attaching a hose from the fuel filter output to a bucket to prevent a mess and possible fire please ). Can you hear the fuel pump running? Could be a blown fuse for the fuel pump.

My s10 will turn over, but wont squirt gas through injecter


Does it crank? Do you have any codes? Check engine light? Do you have spark? No spark check coil, and connections, also it would be nice to know what year it is. Get codes read. No crank check battery and starter. No codes or lights check crank position sensor, make sure your pcm is good after replacing your ignition mod you could have blown it if you did do it right. (engine computer) Check cam sensor if applies. Crank and cam could prevent it from starting and I know one I think cam controls pcm's fuel delivery on gm's
