How can I tell if my Mazda 6 has no spark?
You have no spark did you check to see if the fuel pump activates when you switch on the ignition ,should activate for 2 seconds and activate again when you crank the engine . I did check for codes and it is giving a P0335 code. I checked wires leading to the sensor and also just replaced the sensor to be 100% sure. Still no spark.
What makes up the 4 cylinder coil pack?
One ignition coil within the coil pack fires spark to cylinders 1 and 4. The other ignition coil that makes up the other part of the coil pack fires cylinders 2 and 3.
Why is no spark coming out of coil pack?
CASE 1: If the test light lights up. This result lets you know that the coil pack is receiving power and that the power circuit requires no further testing. If you Ford (or Mercury) car or truck still has NO SPARK coming out of any of the spark plug wires, this could possibly due to three things: Bad spark plug wires. Bad coil pack.
Can a bad coil pack cause a misfire?
CASE 2: You got spark from only one coil pack tower. This result confirms that the ignition coil is bad. Replacing the ignition coil pack will solve the misfire condition and the misfire code lighting up the check engine light (CEL) on the instrument cluster.

What was the p0335 code on my Mazda 6?
Cranked with alternator plug disconnected… still no start.P0335 code is gone, now giving a U2516 code.Fuses all test OK, relays click when key turned to ON position.This all coming after a simple alternator swap has me baffled. I’ve checked wires all around that area to make sure I didn’t knock anything loose but all “appears” normal.
Why are there spark plugs in my Mazda 3?
Took out the spark plugs, then rotated the crankshaft pulley and I could see the camshaft rotate, so that meant to me the timing chain is still in one piece and at least partially functional. Next put a screwdriver into spark plug hole #1 and set the crankshaft pulley to its timing mark.

Why does my Mazda 3 crank but not start?
Not sure if this is relevant or not. After doing a routine oil change in my garage, the engine will crank (pulleys and belts rotate), but it does not start. I called AAA, they showed up and immediately hooked up a battery booster.
What causes a Mazda engine to not start?
A problem that may cause no-start problems on a Mazda or lead to the engine running rough is a failed crankshaft position sensor. A Mazda crankshaft position sensor (CPS) monitors the position and rotation speed of the crankshaft. Mazda cranks but won’t start.
Where is the CPS sensor located on a Mazda?
Follow these steps to change the crankshaft position sensor on a Mazda. Park your Mazda on level ground. Engage parking brakes. Let the engine cool down. Jack up the front right (passenger) side wheel. The CPS sensor is located on the same side that you have the serpentine belt.
What causes the ignition coil to spark while cranking?
So there are two wire inputs into the coil?If so one is a constant power and the other is a pulsing ground while cranking that is what causes the coil to spark . also with the distributor cap off and cranking the engine the rotor on the distributor spins while the engine is cranking?

What can I do if my ignition coil is not working?
Used a multi-meter to measure the resistance of the ignition coil and found the measured resistance was within specifications. Connected a lab scope to the ignition coil primary signal circuit, started the engine and found an erratic signal.

Why does Mazda 6 I 2.3L engine not start?
Otherwise you have already done all the testing possible to prove that the entire vehicle is operating properly and the only possible cause is a faulty PCM. All Mazda service manual no start diagnosis step have a final test that says if all other test prove out ok then the next step is to replace the PCM.
How to know if your engine has no spark?
First Confirm Your Engine Has No Spark. 1 Disable the fuel system by removing the fuel pump fuse or relay. 2 Insert a spark plug tester into the plug boot and ground it on a piece of metal on the engine. 3 Finally, Have someone crank the engine and watch for spark.
Why does my Mazda 3 not want to start?
You’re getting oil on your spark plug; replace the valve cover gasket, it isn’t very hard, basic tools are needed, and a valve cover gasket kit from a dealership and some gasket maker silicon. It could just be a severe enough leak going through #4 to not want to start.
What kind of spark does a Mazda 3 have?
I check the spark by taking out all the spark plugs, then holding one after the other against the metal block and checking for spark while someone turned the ignition. All 4 plugs showed spark, and they looked strong with a bluish spark color.
Why does my Nissan Altima have no spark?
I am now pushing a 2005 Altima with 2.5l because it will spin over but fails to start. No codes show on my snap-on scanner. It has no spark, the tack does not move. We changed the crank sensor, and no change. My scanner said that it should have 5 vdc on one pin of the connector and that the sensor should ohm out at 165 to 200 ohms.

Why does my Nissan club have no spark?
It has no spark, the tack does not move. We changed the crank sensor, and no change. My scanner said that it should have 5 vdc on one pin of the connector and that the sensor should ohm out at 165 to 200 ohms. When I tested the plug I had 12 vdc and the sensor reads open across all the pins. Did you rebuild the motor? did it die when driving.
Why does my car not start when I crank the engine?
The crankshaft position (CKP) sensor monitors the position or rotational speed of the crankshaft. If the crankshaft position sensor has failed completely, and isn’t sending a signal to the (ECU) at all, then the computer won’t send any fuel to the injectors. This will leave you unable to start the car.
What should I do if my engine won’t start?
You should see a bright spark jumping the gap in the spark tester. If you don’t see a spark, repeat the test. This time, adjust the spark tester to 30KV. If you still don’t see a spark, repeat the test and set the tester to 10KV. If this time you see a spark or no spark, you have a problem with the ignition system.
