SOURCE: 1991 honda accord "no spark"

There is a relay mounted way up under the dash on the driver side. It is about 1"x1"x2" and it says Mitsuba on it. This is the PGMFI relay, sometimes called the main relay or fuel injection relay. It is very likely the problem. You can buy another one, or there was a bulletin on how to repair it. You need to take it out, pop the cover off, and resolder the cracked solder joints on the pc board that the relays are mounted on. Really not that hard if you have a little soldering experience. If not, just buy another one, about 50 bucks.cb28323.jpg

SOURCE: No spark?

Hi, common thing with the mazda was the coil or the ignition amplifier going faulty, both of which are located within the distributor, the coil ususally gives the symptoms you describe, a weak spark. The coil is the most common failure aswell for your vehicle i would recommend a new one, also make sure distributor is spinning as it could just be a case of a broken timing belt.

Good luck Davelee

1989 chevys10blazer won't start turns over but won't start one mechanic said it jumped time another one said ignition. Coil or distributor cap put gas in carburetor but it still didn't start


Pull off a spark plug wire and ground it over the engine. Crank the engine over and see if there is any spark from the wire. Sounds as if there is no spark to light the fuel you are putting in the carb. If no spark, possible ignition module/pick up coil inside the distributor/defective distributor cap/rotor/ignition coil/ wiring

Why is there no spark from spark plug 1995 k1500 silveraldo


1995 silverado has a distributor, remove the the distributor cap, make sure the distributor spins with the engine. also make sure the ignition rotor is not burned out or have a hole were it makes contact with the cap. also make sure the cap has a good carbon inside to make contact with the rotor, at this time get a screw driver, put it on the end of the wire from the coil to the cap, don't touch the metal part of the screwdriver, it will shock you if good, so put it at 5/16 from any metal on the engine, bracket, alternator , thermostat housing no matter, some one turns the engine over, check to see if the coil produces a spark, if the rotor turns, if ok it should have spark on all the wires, if it has no spark, remove the wire from the ignition coil and check if you have spak at the coil, if you have no spark, try getting a wire lead, connect it from the battery ground on one end, a screw driver on the coil to check for spark, and the other end of the wire with the key on, touch the - negative plug on the coil, that should produce a spark, if not spark yet, make sure you do have power at the coil with key on, if you do and it doesn't produce spark, replace coil. if it does spark but it is weak or yellow in color, replace coil. if coil is fine, replace distributor module,

Ignition mystery! 1994 GMC Suburban 2500 5.7 mtr. No spark to spark plugs. Have spark from coil to distributor. Have changed coil wire, cap, rotor, ignition module, and coil. have 12.5 volts going to...


I guess you could have the ignition analyzed on an oscilloscope. Maybe a tech could see something then.
I always heard the only gap was the spark plug gap-the rotor has no gap-are you sure you got the correct rotor? And does it touch the top distributor cap coil wire tower?

Let us know. It is a mystery worthy of a solution.

On a 1992 chevy 1500- 350 engine, I can not get this thing to get a spark- i have replaced the plugs and wire, distributor cap and rotor, but you still don't even get a spark, it's getting fuel... Please...


Hi, Hope I can help you.
I do not know how you have checked for spark, but lets start from the beginning.
Lets start with an ignition systems check.
1. I want you to remove the high voltage coil wire. ( That's the wire in the center of the distributor cap.) Using a good pair of insulated pliers. I want you to hold it about 1/4 inch from a good engine ground. Now you will need a bit of help from a partner. Get them to turn the key and crank the engine. You should see a bright blue and well defined spark. Ok, If you have spark I want you to slowly move the coil wire away from the engine ground. As you do this I want you to pay attention to the coil tower. (The coil tower is where the other end of the coil wire is attached.) What your looking for is arcing and sparking at the coil tower. If this happens then you need to replace the coil with a new one. If this does not happen then your coil is working fine, and we will have to move on.
Note if you do not get spark from the coil wire replace the coil.

2. Ok if you have spark now we have find out if the spark is making it to the spark plugs. How are we going to do this? By checking the rotor, distributor cap, spark plug wires and spark plugs.First lets remove the distributor cap. This will allow use to inspected the rotor and the distributor cap. What your looking for is, cracks, carbon tracks and wear at the tip of the rotor. On the distributor ,look inside the cap for cracks, carbon tracks and wear on the terminals. If you find any of this replace the distributor cap and rotor. ( Note if you have any doubt of the condition of the rotor or the cap replace them.) Next lets check your spark plug wires. Lets pull off one of the spark plug wires from the spark plug side. Now inspect the wire connection for a white crusty powder. If you find crust replace your wires. Now you should check all of them the same way, but if even one has corrosion replace them all. You are going to have to inspect the wire its self . Going down the whole length of the wire. Holes cracks burn Marks and other damage. Once again if you find any damage replace them all.
I hope this will help you and good luck to all the read this FixYa
leave feedback thank you

Van will not start I have fuel pressure and when cranking it builds oil pressure where do i go from here


Check for spark at the spark plugs. If no spark, remove distributor cap and inspect the inside of the cap and the rotor for obvious signs of wear or damage. Check for spark at the coil wire by removing the coil wire from the center of the distibutor cap, and, holding the end of it close to the engine block, have someone crank the engine. There should be a very strong spark. If there was spark at the coil but not at the plugs, replace the distributor cap and rotor. If there is no spark at the coil, you either have no power or ground at the coil, or the coil is bad. With the ignition ON, there should be 12v at the red wire for the ignition coil. if not, check the fuses. Check for the pulsing ground signal of the ignition coil at the other wire ( I think a white wire) using a test light clipped to battery + while the engine is being cranked. If there is no light, the problem is likely the ignition module or pick-up coil, which is located in the distributor. Make sure that the wiring and connections are in good shape for these items before condemning them.
Pick-up coil should have about 1500 ω of resistance.
Good Luck

1997 jeep cherokee 4l will not start on petrol or lpg


Here are a couple of things that could be causing your problem. 1. Bad ignition coil or ignition module 2. Clogged fuel filter 3. Clogged air filter 4. Clogged fuel injectors 5. Bad spark plugs, wires, distributor cap and /or rotor. 6. Broken timing chain/belt. Here are a few things you can try to verify that you have a good spark. 1. Remove the distributor cap and crank the car. If the rotor turned you're ok. If it doesn't turn then that's you're problem and you will probably need to change a timing belt/chain. 2. Check the spark from the ignition coil by pulling the coil wire from the center of the distributor. Use an alligator clip to attach a short wire to the coil wire contact. Bare the other end of this short wire and set it up so it's sitting very close to the engine block. Turn off the lights and try to start the car. You should see a spark jump from this wire to the block. If you don't see a spark it's likely your ignition module or ignition coil is bad. 3. If you have a spark maybe it's not getting to the plugs. You may need to replace the distributor cap and rotor. You can test if the plugs are sparking by pulling one, re-attaching the spark plug wire and seeing if you get a spark when you try to start the engine in the dark. Please note, the metal threads of the spark plug need to be shorted to the engine block to complete the circuit during this test.

I had the same problem with my 85 cj7 this week, I relpaced the ignition control module, plugs, wires, cap, rotor and the the coil; still had no fire to plugs. the problem turned out to be my distributor, replaced it today and she fired right up. Most likely it was the pick up module in the distributor that went bad.
