Is your check engine light on? If it is, then you most likely have a bad sensor. Also check all your relays, fuses, fuel pressure, and check for spark.

Here are the possible causes:

  • Bad Igntion Switch: If your battery checks out, but the starter is still silent, it may be a faulty ignition switch. Turn the key to the on position (not all the way to start). If the red warning lights on your dash don't light up (and your battery connections are clean), the ignition switch is bad. If they do light up, turn the key to the start position. The dash warning lights should turn off at this key position (most cars). If you're not sure, turn on the headlights. When you try to start the car, the lights should either dim (a lot) or turn off completely. If they do, your ignition switch should be ok. If not, the switch will need replacement.
  • Bad Starter Connection: Corrosion can not only keep your battery from connecting, it can affect any electrical component, especially the ones exposed to the elements like the starter. If you have a helper, you can test the connection by holding a circuit tester lead on the wire that engages the starter. This is the smaller of the two wires connected to the starter. Be sure no part of your body is near the moving parts of the engine - it could still start at any time! Have a friend turn the key and check the current. If you're getting current to the starter but it ain't spinning, it needs replacement.
If your starter spins freely when you turn the key, the problem lies elsewhere. Now you begin to check the other systems that could keep it from firing up.

    Since you already checked all of the things that were advised you to check and they are all good. I would suggest you to get an auto mechanic (diesel expert) and ask for second opinion.

    BTW, does it have an injection pump? If yes, try to press the injection pump 2 or 3 times and then try starting the engine again. But if you get the same problem, contact a mechanic.

    Have a great day!

I have a 2003 KIA Sorento 2.5 CRDI,cranks but does not start.


You may need a fuel pump. Please remove and check the fuel filter for metal and debris (could be clogged?) If there is metal filings found inside the filter. That is an indication of a fuel pump failure. I hope that helps, good luck.

Just bought a used 1989 Delta 88 Royale Brougham. It worked fine but when I got it home and plugged it in (its winter) it won't start now. It turns over but won't stay running


is this a diesel? surely not. the plug in heats the oil in the oil pan to make the engine start easily in wintertime. you may have a faulty plugin, or if someones installed a deisel motor, you most likely have bad glow plugs,hmmm if gas, i suggest you check for faulty oildipsick heater or bad or weak fuel filter,fuel pump, it really makes a difference whether it's deisel or gas. please repost if this does'nt help, thank you for choosing fixya.com

Have someone retime the engine. In a diesel it means to time the injection pump. You may have wear in the timing chain or gears. But the fuel ratio can be made rich or lean by when the fuel hits the cylinder.

Try that first as it is cheaper. You can have worn injectors and adding a cleaner will make the fuel run through faster. Possibly spray a little better, but it will not make the fuel nozzles any tighter.

Mistakinly put 50 litres diesel in my almost empty petrol tank


The first thing i'd tell you is to not run the engine at all before fixing this if possible. Diesel fuel doesn't burn very good in a gasoline engine, if at all... There is not enough compression in a gas engine to get the diesel hot enough to burn, even with a spark plug.

There is a few ways to go about this but the easiest one is to find and disconnect the line coming from the gas tank to the engine, as close to the fuel pump as possible (preferably before the filter) and route it to an empty container, then jump 12V to the fuel pump motor terminals, or jump the fuel pump relay terminals (to get the pump running) and let it pump the diesel fuel out in the container...

As a precaution I'd change the fuel filter after this, fill the tank back up with clean gasoline, and give the car a good run... You can expect the engine to smoke and run bad for a little while, as there will still be a little diesel going through.

As for the cost to get it done, I really couldn't give you a straight answer... They could do it like I said or another way (drop the gas tank...) It's not that hard to do if you do it yourself or find someone you know who can do it or a good "backyard" mechanic, but I'm sure some of the shops out there could write up a nice repair bill for this...

The car's peformance has been poor, especially on picking from a stationary position (no power).


I would suggest to have the pump timing reset and probably have a diesel specialist to check the pump as well. It is very difficult to give extra help over the net as most of the things have been covered by the mechanic I supposed. But as per your description I think the pump may have not been timed properly or it may need overhauling as well.

Engine knocking.


Hi,my 92 prado started making a knocking sound recently,we couldn't pin it down to one spot in the engine.
The knocking was constant at low revs and then disapeared.
Turned out to be the tourque converter knob had bust of and eventually destroyed the fly wheel and the transmission pump.
Definatley check under top cover and also drop off the sump to check for loose nuts etc.
hope this helps.

Engine problem.


Hi Michael,

The motor shut off and the engine light came on, you won’t start right away and you wait a couple of days and start it again, sounds like your engine was over heated and because it is too hot and the engine frozen.

There are several kinds of engines, water cooling ,oil cooling and air cooling.

Over heated can cause many different problems for the cars, you should check step by step yourself.

Water cooling engine; if you know, you can help somebody.


1. Check the radiator see if you have enough coolant
2. Check the oil see if you have enough oil
3. check the water pump see if the water pump works fine
4. check the thermostat see it is function right.


Suppose your radiator has water or coolant, leave your radiator cap open, start your engine, let it is running 10 to 15 minutes and wait it is getting hot and see the water in your radiator, if the water moves, that means your cooling system works fine, otherwise either the thermostat frozen or the water pump was broken.

You mentioned when you re-start your car, sounds like a diesel engine, please check the where the noise from, if the noise from the water pump area, that means you need to change the water pump. When you change the water pump, change the thermostat at the same time, because when the engine over heated, the thermostat maybe damaged.

Oil cooling engine, check the oil pump. If the noise from the oil pump, you need change it.


Good luck,

Frank
