No spark to the sparkplugs

You have two possible areas to check - fuel or electrical systems.

Is fuel getting to the engine? It is possible you have a clogged fuel filter OR a dead fuel pump. To check it, disconnect the fuel line from the injector system at the engine, and have someone "bump" the starter to see if fuel comes out. If it does the pump is working but perhaps not with sufficient pressure to run the engine. Checking that requires special tools, a job for a pro.


Is there ignition spark from the sparkplugs? Try pulling one of the plugs out of the engine, and lay it on the engine block in direct contact with the metal and have someone try to start the engine. If you see a spark jump the gap on the plug, you have spark. If it does work, try each sparkplug, and if there is positive spark on all cylinders it is possible the ignition timing is bad or maladjusted. In this case unless you know what you are doing it is better to have a pro mechanic work on it.

What make vehicle ? Ignition module ? ECM/PCM

You are a OBD 1 and there is a connection for that,you could jump two wire and read the Check engine light flashes, Inside your distributor is a ignition control module, when you vehicle does not start you need to check for spark,with a sparkplug 1/4 from engine ground have someone crank the car if there is no spark a ignition module will be needed.

Let's get The terminology right to start out with. If the engine turns it cranks so you have a crank no start. Am I correct? Make sure you have spark. If no spark check your crank sensor located in the bell housing (transmission). Make sure you got fuel injector pulse, fuel pressure.

Could be alot of things but since it only acts up when hot that narrows a few things. Put new sparkplugs in. Run the car until it starts acting up, turn the car off let it cool then take out the spark plugs but keep them in the boot of the cylinder it came out of check the color of all of the plugs. Which one or more look oil caked up? If you can read a sparkplug they willl tell you the problem most of the time on older vehicles. If not this the problems probably in fuel delivery system filters or pump.

First check for spark at any of the sparkplugs.

First check and see if you have spark at the sparkplug, if you do then check the fuel pressure if its not within specs replace fuel pump.

First check for spark if you are getting spark at the sparkplug then, check fuel pressure it not within specs replace pump

it could be many things - this is what a mechanic would check.

the main things you need to start the engine is fuel a spark and air.
if one if these are not present the vehicle will not start.
check that the air filter is not blocked
check that the ignition sytem is working and a spark is present at the spark plugs and that they are clean and set correctly.

if the vehicle is running on diesel ensure the injectors are working a spark is not needed as the fuel will ingite through compression.

ensure that fuel is getting into the cylinder and that the cylinders have compression. this can be checked by fitting a compression guage in the sparkplug hole and cranking over the engine.

check that the exhaused is not blocked and that the burned gas can escape.

i hope this was helpful.

you can check for spark by plugging in one of your old sparkplugs to one of the spark plug cables and letting the sparkplug lay on the bare metal of the engine. Turn over engine to see if the spark plug is producing a spark. No spark? Check under the distributor cap, take a look at the rotor for damage.
