    I see no blue smoke. only have to add about a half pint of oil between oil changes.I only have 1 spark plug when I changed them that was oily. The rest were clean but very white on ends. You could smell the gas coming from spark plug whole. I asked for the spark plugs that would fit my car. I ve been buying the right ones. I just buy the cheat ones cause at about 500 miles my car will not go any further. I just had my coil/coil pack changed about 10,000 miles ago. My car has about 170,000 miles on it. What is the throttle body?

Generally speaking it will be oil fowling plugs rather than fuel, but to do it that quickly you should be seeing lots of blue smoke and a sinking oil level. I have seen fuel fowl plugs but generally **** fuel. you should probably check the plugs are the correct ones for the car, all plugs have differing uses and just cause they fit dont make em right. you could also look at the condition of the rest of your ignition system ie condition of leads, coil/coil packs. Another thing you could check it the condition of the throttle body, looking for fuel colouring additive build up, or even wether it is set correctly (obviously a job for diagnostic tool).

I have no plug wire spark 1997 dodge average 2.5 v6 24 value.have already replaced crankshaft positioning sensor on it and still no spark to the wires

Sounds like a bad distributor. Had you pulled a spark plug out you may have found them wet with gas after cranking. If they are wet the crank sensor is working since both injector pulse and coil pulse rely on crank signal.

The distributors are known week points in the ignition system and used to be common when theses cars where still on the road. A reman will run you $250 U.S.

No,4 plug not fireing changed plug coil.plug ran good for 100 miles then 4 stop again

You would need to figure out if it is a problem inside the cylinder or with something like the crank-cam sensor firing the coil. I would change the plug again to see if it works for a few days.
Could be a problem with the fuel injector or a vac leak if the plug is firing but no power from that cylinder.

From what you have said I would try a new set of spark plugs. Why I am saying this is because when you lost your belt you ran off the power in the battery until there wasn't enough power to run the ignition system properly which caused you spark plugs to foul out. When your plugs foul out and get gas soaked they will not fire as good as they should.When you change your plugs turn the motor over with the plugs out to clear the cylinders. Make sure to use anti-seize on the threads of your new plugs to keep them from corroding to the cylinder head this will make it easier to get the plugs out the next time they need to be changed without damaging the threads in the cylinder head.

Ok this problem is gotton worse. now i replaced the fuel pump and it wont turn over , i have fuel to the injector and spark to the plug. it cranks an cranks if i pump the gas it almost starts. what can it...

Try starting it with the throttle open all the way. It may have to much fuel in the cylinders. If it acts like it wants to start or starts and dies replace the spark plugs, they are probably gas fouled.

Spark Plug Life


30,000 miles is about right for changing standard spark plugs. You can install upgraded (and more expensive) Iridium tipped plugs which are claimed to last up to 100,000 miles but on a standard vehicle 30,000 is the correct replacement mileage interval.

Stick to the vehicles recommended service schedule and never mind what your friend says! Afterall these service intervals are already designed for a vehicle running on unleaded!

Carbon build up on plugs has a lot more to do with correct oil and oil filter changes than unleaded fuel.

Hope this helps. Please do rate my answer

2000 Ford Taurus 6 cylinder with the alternate

i would check the fuel injector o # 5 cyl... if the injector is leaking it will foul the plug out and cause a skip. the next time it happens remove the plug and check for wetness. you may also be able to put a fuel pressure tester on, if so install the tester, turn the key on 2 or 3 times leaving the key in the on position at the end, do not crank the engine, watch the tester for a minute or so and watch for a pressure drop.

Cranks but won't start

1. cranking is "turning over". Starting is what it is not doing. Did you check for spark at plugs when cranking? Why did you change battery?
If fuel line is frozen, generally freeze takes place in the line. Anything you add to tank will not help at this point. (you can heat line with a hair dryer etc (no torches) Most fuels today contain some alcohol so antifreeze for fuel is pretty much redundant. If you have been cranking it fore some time, it would be a good idea to check spark plugs to make sure they are still dry and not fuel fouled... Liquid gasoline does not burn... only fumes ignite. In cold weather, fuel does not vaporize properly and can easily foul plugs.
