Why am i not recieving sparks?

post 3, adds, no spark , 2/3 (and still no year, no country stated)
bad coil pack?
wired wrong, this pack.
no photo of the engine, nor real name of it, Petrol.
btw, we dont have "BAKKIE" here. not a single one.
nor KB trucks, either.
what spark system this car has, im clueless.
4 coils or 1 pack.? if one pack , replace all spark wires
if one pack system , if either 2/3 wire opens, both cylinders go dead. try new spark wires. high voltage,

or you measured spark wrong, on 1 pack car.
it takes 2 spark plugs do do that. 2 good plugs and 2 good wires,
#2 and #3, due to the fact they are wired, in SERIES.
see its called wasted spark system, with 1 coil pack and no distributor..
the testing is unique. on this, setup.
try new spark plugs, gapped correctly
and 4 new HV wires,
I bet its go. if not the coil pack is toasted.

Coil packs do not have firing orders, engines do. I suspect you were given the incorrect part.

Did you ever find out why? my amigo is not getting spark from the coil pack on cyl 2&3. It's a new coil pack and wires and plugs.and PCM. Still no spark from coil pack.

1. Check the gap at the base of the new spark plugs with a spark plug gap tool. If the gap on any plug is not between 0.039 and 0.043, exchange the plug for a new one. Do not attempt to adjust the gap on the plugs.
2. Open the two latches on the passenger's side of the air-filter box. Pull the front half of the air box toward the front of the engine and push it to the side. Remove the air filter from inside the air-filter box. This allows you access to the ignition coil packs.
3. Unplug the wiring harness from the top of one coil pack. Remove the bolt securing the coil pack with a ratchet and socket, and pull the coil up from the engine.
4. Remove the spark plug using a ratchet, 6-inch extension and a spark plug socket.
5. Hand-tighten the new spark plug into the RAV4's engine and torque it to 14 foot-pounds with a torque wrench, 6-inch extension and a spark plug socket.
6. Squeeze a small amount of dielectric grease into the rubber boot at the bottom of the ignition coil pack. Push the coil pack onto the new spark plug until it clicks into place. Tighten the coil pack bolt to 6 to 7 foot-pounds with a torque wrench, 6-inch extension and a spark plug socket. Reconnect the wiring harness on the top of the coil pack.
7. Replace all four spark plugs, by repeating Steps 4 through 7 on all four plugs.
8. Sit the air filter back into the air-filter box. Reinstall the front half of the air-filter box and close the latches to lock it in place.


good luck

You need battery power and timing control from the engine. They spark is created is to energize the coil and then remove the voltage, creating a large spark on the secondary side. I don't really know if this is electronic ignition or the old points and distributor system, but I would look to see that power is getting to the primary side of the coil pack.

Check engine light on ? Code's ? What engine ? 2.3 l 4cylinder or 3.ol v-6 This vehicle has coil on plug ignition system , not coil packs ! a coil per cylinder . If new coils an still has no spark , has no B+ voltage to the coil or the PCM isn't controlling them . Without testing i'd only be guessing as to the problem .If the repair shop you had it to can only say it had to be the coils , I'd find another shop to take it to !
Autolite Coil on Plug Ignition troubleshooting

An ignition module tells the coil packs when to spark. Autozones can test ignition modules for free. (helps them make a sale)

Did you replace the coil pack or just verify 12 volt power to it? if both old and new coil packs have the same issue, (no spark on 2 and 6), then the harness to the coil pack has broken wires or bad connection(in the connector itself), or the computer is faulty. I believe each plug wire tower on the coil pack has it's own signal wire in the harness. Understand that the towers are "paired" together.
For example, cylinder layout.... 1 - 2 - 3
4 - 5 - 6
Depending on the firing order and the actual layout of your cylinder's the above layout would mean
1 and 4 get the signal to spark,(at the same time), even though 1 is on its power stroke, and 4 is on its exhaust stroke. Hope this is clear as mud!

Try switching your coil packs around see if you can get spark out of the 2 & 5 with a different coil pack in that location. If that doesn't work maybe your ICM they can test the ICM at autozone, but can't test the coil packs.

A flashing light means you're actively misfiring. Have the ECU scanned to find out which cylinder it is. Bad coil packs are common and there is a recall for them. Call a dealer with your VIN number and if yours qualifies, you'll get four new ones free. If not, buy a coil pack for each cylinder that is indicated as misfiring and replace them. They're $35 at AutoZone and about $160 at an Audi dealer.
