Check the distributor and the hei coil.
In 1973 you would not have an HEI coil. Just the coil itself. Check to make sure all the wires to the coil, including the plug wire is tight and secure. You can pull the distributor wire from the coil.....leaving a small amount of space between it and the coil, turn over the engine. See if there is a spark jumping from the coil to the wire. If so, the problem is in the distributor. Points and condensor, rotor, etc.
Check engine compression Check engine timing
check for spark at plugs,coil.check you are getting fuel check ignition condensor
It might be that you are not getting spark to your spark plug. Check your coil and the connection to yourcoil. If coil is giving spark check the spark plugs and the spark plug wire. The fumes that you smell is the gas that is being pumped into the engine but not being burned because there is no spark. that is my opinion, I may be wrong.
If the check engine light is or has illuminated, check for codes.
Check the ignition circuit in the Storm. Start by checking the crank position sensor, then the coil pack to find the lack of spark.
An engine which cranks but will not start is not receiving enough fuel or has no spark. A clogged fuel filter or bad spark plugs often cause this problem.
cvheck the fuel pump.if that dont fix it check to see you have spark by touching the spark plug wire to the block if it has spark then that ain't it. otherwise take it to thne dealership and have them put in on a diaognosdtic machine if it has the check engine light on
The engine needs fuel, compression and spark to run, it is missing one of those.
check to see if the spark plug wires are fireing
check the spark plugs or cylinders. you also may want to test the battery to see how much juice is in them. another possibility is gasoline not getting to the engine so I'd check the gas line as well.
The easiest way to find out is to remove the wire from the spark plug and hold it about 1/4 inch from ground (the engine block is good) while someone cranks the engine in short bursts. If you are getting spark you should see a blue spark jump fromt the wire to the engine block. You might want to check all spark plug wires while you're at it. If you want to check the spark plug while you're at it, remove the spark plug and attach it to the end of the wire before checking for spark. If you get spark through wire but not through the spark plug, the spark plug is bad.
engine cranks but wont start means one of these things.. Air, Fuel, Spark, or compression
