erik the wrench is here, we test for fuel, test the coil and distributor / ignition. Truck was completely restored 20000 miles ago so mechanically it’s a … Have replaced spark plugs, had starter and battery tested. Edelbrock 600cfm carb is 6 months old. The pickup coil monitors the rotation of the distributor and triggers the ignition system at the optimal moment to produce the best timed spark for best engine performance. Browse Recommended Tools & Supplies For This Build As shown in the Crank/No Start video , you can easily check for spark with a spark … I have been chasing issues with this HEI for a while now. Dirty, increased resistance, failure, or, no contact, coil won't fire. Inductive pickup on timing light is not working properly (weak) resulting in tolerance stack-up where it does not work on some engines. I bought a new cap, rotor, control module, coil, spark plugs, and the wires. Would crank normally but not start. It's around $40.00 and it's under the rotor in the distributor assembly. To check the secondary resistance, remove the screws that hold the coil in the cap, remove the coil and touch the negative meter lead to the ring terminal on the black wire (between the red and yellow) and touch the positive lead to the bottom of the coil where the rotor bushing makes contact. HEI coils have a grounding bar under them, goes from the coil yoke to the center terminal of the 3 wire connector, and to distributor ground. I was experiencing weak/intermittent spark on my 1989 EZGO 3PG so I did the HEI conversion using a BWD CBE4 ignition control module and a BWD E41 ignition coil and it's not going well. Rotor/Cap problem resulting in voltage drop at spark plug terminals. engine cranks but don't start? The Intermittent Pilot uses a Spark Ignitor to ignite a pilot flame, that then in turn ignites the main burners. 4. Good luck and keep me posted, be glad to help. When outside temp. Older rotors were made form lower quality plastics and can transmit spark through them, increasing resistance and heat, failure. No-spark conditions can have a number of causes, but for starters, we need to know if we have spark when we crank the engine. dropped in teens one morning it wouldn’t start. The cart starts up great, runs great for 100 feet or so, then it's like the spark just dies and the engine stalls/cuts out. At first I had no spark while cranking but as soon as I released the key it would sputter on occasion. Replace HEI distributor and no start. Keeping your spark plugs in optimum condition can reduce your chances of experiencing an ignition coil failure. Check the red lead wire to the HEI for voltage, there should be 12 volts. Some simple regular maintenance will save you a lot of money in the long run. Truck ran fine with no indication of problem. I have 13V at the distributor. The engine will not fire, and i have intermittent, if any spark. The rotor turns when the engine is cranking. Spark Plug wire made out of some super insulator that blocks timing light inductive pickup. The reason I am testing this HEI is I have a no start condition. It common for the ICM to fail on the HEI system and if you go to Auto Zone, they can give you the step by step instructions to replace the ICM. The primary resistance value should be between 0.6 – 1.5 ohms. 3. The engine ran fine before i pulled it out of my olds and stuck it into my s10. All are good. 2. If the gap in your spark plug widens due to normal erosion, it leads to an increased voltage being required to create a spark in the chamber. HEI Coil output is weak. Found no spark. 1. On top of that I found I also have an intermittent and weak spark. The High Energy Spark Igniter (HEI) is a Class 3 (special) igniter used for direct spark ignition of oil or gas igniters or small burners. don't worry! I have a SBC 350 with hei ignition.
