You can take the ignition module to get tested at an auto parts store to test the ignition coil you can either pull the boot off of the cap and put a screwdriver on it and crank it it will shoot blue sparks and its good if it sparks if not then it the igniton coil that is bad. if thats not it then take the cap off inspect the rotor if it has a burn mark ist proably history and how to check the pickup coil put a screwdriver next to it it is magnetic and also you can ohm it out with a test light just to be sure.

please keep me updated

SOURCE: Have replaced the starter solenoid, spark plugs,

If you haven't already done so, replace the distributor cap and rotor. There is most likely corrosion inside the cap that is causing a crossfire condition.

This is a common problem on that engine.

Don't know why being hot would aggravate it, but start with the cap.

My 2001 mercury sable has new altinater,battery, and spark plug but won't fire up.What could be the problem?


Are you getting fuel pressure? You have an inertia switch in the trunk and it might need reset(push the red button down). It shuts off the electric fuel pump in case you have an accident or get bumped hard.Sometimes they just actuate for no known reason.
Also crankshaft position sensor could be dead. Have you run the engine codes? don-ohio (:^)

MY PLYMOUTH GRAND VOYAGER 'S HEADLIGHT'S AND DASH LIGHTS WORK, BUT THE ENGINE WON'T TURN OVER. THERE IS NO SPARK COMING FROM THE ELECTRICAL WIRES.


When you say no spark, are you talking about the spark plugs, or just the general wiring?

If the engine won't turn over, then it isn't moving, and if it isn't moving then you need to check the following in this order:

1) Does the battery have power i.e. around 12.4 volts or over?No? Charge, test or replace battery.

2) Do the car's head lights dim considerably if turned on when attempting to crank? Yes? Possible lack of battery charge or faulty battery.

3) Assuming the battery is fine, can you turn the dash warning lights on and off with the key? No? Faulty ignition switch.

4) Is there a click sound when you turn the key, but no starter motor spin? Check starter motor connections or replace starter motor.


If none of the above prove to be of help, then please report.

86 s-10, 2.8 v6. Changed the distributor and button, will not fire. Definitely have the firing order correct, and have spark all the way to the plugs. Turns but won't even try to fire. Firing order is...


It would be easy enough if that was the firing order but it isn't. The firing order is1-6-5-4-3-2. The odd numbers are on the driver's side front to back and the even numbers on the passenger side. #1 on the distributor points to the front of the engine and the distributor turns clockwise. Hope this helps.

1990 Buick Century Custom 4-Dr Sedan 3300 V6. New motor, fuel pump, fuel filter, alternator and starter. Turns over, though it won't fire.


Check your fuel pressure at the schraeder valve that is on the fuel rail. If you have fuel pressure, check for spark.If no spark, then ignition diagnosis is needed.If no fuel pressure, check for diconnected, or pinched wires, as this can easily happen during an engine swap.

My 1996 850 volvo wont start the engine turns over but wont crank


ok, turning over and cranking are the same thing, what your saying is it won't fire, so , 2 things make a motor fire, electric and fuel, so starting with the easiest remedy , remove the distributor cap, and inspect the rotor and connection points that are inside the cap, check for any debris built up , sometimes you can clean them good enough to get the car to fire up, if it does , normally you would replace them , ( not that expensive) remove the number one cylinder spark plug, and once out put the spark plug wire back on it, ( your going to need help with this step) with insulated pliers , hold the plug and place the bottom of the plug against a grounding point (any bolt on the motor will do,, but try and keep it away from the carb as its Hopefully going to spark) have someone try and turn the car over as if to start it, look for spark at the end of the plug, if you have spark,, replace the plug and try and start the car , if it won't,, move onto the fuel problem, you need to make sure that the car is getting fuel, remove the fuel line to the carb turn the key for a second, you should see fuel splashing out, if yes ,, you should be able to start the car , if no,, check the fuel filter first , then the fuel pump,

Changed the plugs wires and cap and rotor...think I might have screwed the firing order up....no misfire just wont turn over.


the wires to the plugs should not keep the motor from cranking over. If the battery is fully charged the ignition switch should engage the starter. If you think the firing order is wrong you need to determine 1 where is top dead center (the position the motor is in when #1 cylinder is at the top of the compression stroke). 2 what direction does the rotor turn 3 what is the firing order One way to make it easy to rotate the motor is to remove the spark plugs. no compression means no resistance to the starter so the motor should turn over with the key in the start position. If it won't crank over with the plugs out then something is wrong with the starter, battery, starter relay, or ignition switch. I always start with the basics. the battery should have at least 12.5 volts. if it does check the battery terminals. even if the starter is weak you should hear a click when the key is turned to the start position. Once you get the starter to turn over the motor you can tell when the number one cylinder is at top dead center by putting a finger over the spark hole as you crank over. You will feel the compression as the cylinder comes up on the compression stroke. I have used a large socket to slowly turn the motor over and when you are near top dead center you should be able to see the degrees of advance on the timing mark. Set the motor at top dead center then see where the rotor lines up with the wires on the distributor cap. that is where number one cylinder should fire. You then follow around in the direction that the rotor turns and the wires will corispond with the firing order. I always make a mark on the number one spot on the cap with a felt pen. That way you have a fixed reference point. Take care to verify that all the wires are to the proper plugs before trying to start. Take extra care at this point and make sure your firing order and rotor rotation are correct. I would triple check this. The firing order and rotor direction are usually somewhere on the autozone repair web site

I have a 1995 dodge neon that would not start after a cold week of sitting. When trying to start it, i decided that the battery was frozen... got a new battery and replaced it... however did not tighten...


When you turn it over by hand it is getting "stuck" on the compression stroke. Take out all the spark plugs and it should turn over easily just in case your "stuck" situation is something more sinister like a broken timing belt causing the valves to hit the pistons (most unlikely). You can then check the condition of the plugs making sure they are not fouled and by cranking the engine with the starter motor to check the spark. You are looking for a nice strong blue regular spark. A small weak spark may not be sufficient to make the engine fire. If the spark is weak take take out the coil lead from the distributor and as it is being cranked see if a strong spark is thrown when you hold the end 6mm away from a grounding point. Work your way either side depending on the spark result to determing where you are loosing spark. If the spark is ok try some starting fluid to see if you can get the engine to fire. If it fires on starting fluid but won't run then the fuel circuit is suspect. If you have fuel pressure at the fuel rail you need to check the injectors are pulsing. You can bye a noid light which plugs into the injector and flashes every time a pulse is received. These cost about $20 form the auto shop. My bet is your sensors are ok though...
