SOURCE: INTERMITTENT SPARK

Make sure the spark plugs are not platinum or anything other than regular copper plugs. The S-series uses a "waste spark" system and will destroy platinum plugs. Regular copper NGKs that came from the factory with the car work the best.

How do you know it is a spark problem? Are you able to verify spark, fuel and compression?

I ask because the usual solution to what you are describing in your problem is replacing the Engine Coolant Temperature Sensor (ECTS). The factory one is plastic and cracks. When it cracks it sends the PCM a signal that the engine is 40F below zero. The PCM will compensate by dumping A LOT of fuel into the engine to try and warm it up. It will cause all kinds of starting and idling problems.

Autozone or the dealer sells the better brass tipped one. The ECTS is located just under and behind the upper radiator hose. You'll need to remove the air intake tubing to see it or get to it. It has two wires going to it and goes into a connector. Squeeze the connector at the "ears" and it will come off.

Now is the time to check the connector for corrosion and gunk. If there is clean it out very well. If there is no gunk or corrosion continue on.

A 10MM DEEP well socket will take it out. Swap it quickly because some coolant will come out (a couple of ounces). Hand tighten it and snug it with the socket (not too much because it will strip out). Connector back on (either direction it's non polar). Put the intake back on and enjoy better starting and idling.

Car wont start

In the circuit between the crank position sensor and the coil packs, is the ignition control module. It not only amplifies the crank position signal, but also does things like set the ignition advance curve as rpm goes up. It is expensive, but could be bad. First check to see it it is getting power, and it is not a fuse or a relay before trying that unit.

I have no spark at the plugs when cranking the engine.

could be a bad pickup coil in distributor or a bad ignition module
hold dist. end of coil wire near like 1/8 inch away from engine block. turn key on ond off while watching for a spark. if you see one then i would try a pickup coil first
also make sure dist turns when you crank it

My nissan

If you have a 12 volt test light put the point on the positive lead to
the coil and the ground lead to a good ground ( Negitive side of battery ). Then turn the key on. If the test light comes on then you have power to the coil. With power to the coil confirmed have someone crank the engine and put the test light on the negitive side of the coil. The light should flash at a rapid steady rate. If not then your pickup in the distributor may be bad. If no power to coil with key on or when cranking you may have a bad ignition switch.
Another way to test for spark is to remove the coil wire from the dist cap and hold the end close to a ground ( 1/4 inch away) and
have some one crank the engine. If you get a good spark but no
spark to the spark plugs you may have a cracked dist cap or a bad rotor. If no spark at coil wire use a wire in place of the coil wire to check for spark. You may have a bad coil wire. Good luck. Neil W.

Code 300

These have a lot of problems with the ignition coils. In darkness look at the coils for any signs of stray spark. If stray spark is present the coils need to be replaced. Note- Use extreme caution around moving engine parts! Do not attempt this if you cannot do so safely.

Give me an update and we'll continue as necessary.
