Check your wiring to all coil packs, they are know to have connection problems.

no, you will need to swap all the sensors and wiring harness from your old engine, you must have gotten a different year engine from the salvage, when swapping engine or transmissions al wise use your original sensors and wiring.

SOURCE: my 1991 300zx non turbo

Given the tests you have already done, my first thought on this would have been the ignition module. If you have a good repore with your parts guy, you may be able to return the ECU. The 3rd wire should be a reference wire. Let me know if you need anything. I am trying to find some manuals for you and will continue to look.

Isuzu 2ltr bakkie nmbr 2 and 3 no spark?


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.

99 chev. tahoe changed plugs and now im not getting fire to the number 1 plug whats wrong


Loretta,, Occasionally, a spark plug is "bad" right out of the box. But a single new plug and install it in the #1 cylinder. Also, on a 15 year old vehicle, it is likely that the spark plug wire wa damaged removing it in order to replace the plug. Good Luck.

Why is my tiburon not getting no spark


There could be a few reasons it doesn't. It may be your spark plugs/coils, wires, distributor, coil pack, cam sensor, dist. cap, even the PCM. You need to test each part to make sure. That would be the only way to actually know. You would need to check the wires and pins. Anyone could cause it.

Not getting spark


need more info (need to know what type of ignition system your vehicle has: (1) traditional ignition coil /distributor system, or (2) electronic ignition, but lack of spark problems are usually a faulty coil
on traditional vehicles, and on the newer electronic ignition cars, total lack of spark would be
a faulty ECM (electronic control module) - partial lack of spark (diagnosed with a HEI (high energy ignition) spark tester kit), would be caused by a faulty coil pack (in the waste spark system), where
there's 1 coil pack for every 2 spark plugs.
I bought my HEI igntion testere kit for $20, but Harbor Freight sells a similar unit for $10.
Hope this helps.

How to change te spark plugs


Hi: If this is your 1st time to Change your Spark Plugs, I recommend that you First of All Get the Correct Spark Plugs from your Auto Parts Store, Then Locate your Spark Plug Wires which run from your Distributor Cap to your Spark Plugs.If you have a V-8 There will be 8 if you Have a V-6 Then You'll have six Spark Plug Wires and 1- COIL Wire which is located in the Center of your Distributor Cap to your Coil. It is the Shortes Wire.I Recommend you ONLY do 1-Spark Plug at a Time, This will Prevent you from getting any of your wires Crossed which will Cause your Engine to Run Rough ,Back Fire or Not even Start,So just Pull off 1-Wire From Spark Plug and one Wire From Your Distributor Cap, You'll Need a Spark Plug Socket Probally 5/8th in. And a Ratchet and 2- Different Size Extensions to beable to reackh all your Spark PlugsNOTE!! Buy you a Spark Plug Wire Tool there not very Expensive but well worth it,This was you Can Pull the Wires with out Damaging Your Wires.And you Might Want to Put NEW Spark Plug Wires On as well, If So and I do Recommend This. And Again Just do 1- Wire and Plug At a Time So you'll know you Have Not Crossed any Wires. Hope This Helps You ,Please Respond by Voting on This Problem And How it Helped You. Thanks From WYOCWBOY

300zx wont start has spark plugs are wet


Wet spark plugs indicate cylinder flooding and the existence of a no spark condition.

Check your fuel and ignition systems for proper operation and repair/replace components as necessary.

Plug changing


You can do a spark plug change and wires without removing anything else. The back three plugs look mind numbingly impossible, but you can (if you don't have meaty hands) get to them from underneath. 
It takes about 2 and 1/2 hrs to change plug and wires. You need a 3 inch socket extension for the plugs and, used a full length handled 3/8 ratchet. A stubby handle ratchet would make removal much easier. 
As for removing the wires; There is a wire loom on the back, the same as is on the front wires. The loom on the back is hard to get un clipped. So be patience, or cut it off. The wires that go to the back are quite short and you didn't have to bother reinstalling the loom. 
You can fish the wires up and out from on top of the engine, just work them slow and carefully. They came out easier than I thought they would. Enjoy.
The other way if you have large hands is to rotate the engine forward. The first time is did it, never again.
Tips about rotating engine forward if you do not have ramps... I don't. Engine needs to be in neutral, ratchet ******** driver side lifting eye, other end goes below radiator frame mount. Haynes manual shows a hook next to condenser - I don't put pointy things next to cores. Cinch up ratchet strap, then remove the 2 dogbones using 13/15 mm socket on the bolt/nut. 
Be sure to remove throttle/cruise cables and the big rubber air intake before rotating the engine.

Coil pack...10 mm screws in front, 13 mm nuts on standoffs next to firewall, 3 Packard connectors. I couldn't pull coil pack out as the wiper linkages were in the way - I just pushed it aside, but I also dremel wire-wheeled the corrosion off the terminals.

I got at rear plugs with 1/2" drive with 1/2-3/8 adapter + 2" extension + deep well plug socket. No u-joints required.

Don't gap the plugs - check with parts store as they should be pre-gapped. Gapping may remove platinum from premium plugs and you don't want to do this. Also, a tough job - buy the best wires/plugs u can as this whole thing took me 5+ hours and I don't want to do again for several years.

Use anti-seize compound on the plugs on about 1/2 the threads farthest from the tip as this will make subsequent removal easier.

Number your plug wires with sharpie on both ends, 1-6, it will help keep them straight.

Front plugs/wires are a snap compared to rear bank. I am not a mechanic, just technical by nature and armed with a Haynes manual - again recommended. 

Good luck and hope this helps, If you have long arms. You can get to the #1 and #5 plugs by going around the engine. 
I had problem's with the Bosch platnum Plugs. Check engine light came on and was getting miss fire. I took them out and replaced them with the OEM AC delco Platnum plugs and never had the problem again.
