98 nissan pathfinder 3.0 wont start new distribitor no fire


What do you mean "the battery still no fire"?

Do you mean that there is no spark at the spark plug?
Have you pulled out a plug, grounded it and cranked the engine to check to see what colour (if any) the spark is?
If there is no spark at the plug, then either change the plugs if they look to be in very poor condition, or change the coil.

Check the plug wire from the ignition coil to the distributor cap.
If you haven't already, replace the distributor cap and rotor.
The GM Vortec's have issues with moisture getting inside the cap and rotor and causing problems.

Inside or directly under the distribitor cap is a plastic ring with either one or two wires attached..... these devices fail and not allow the engine to start.
It happened on my 88 chevy (305 cu in.). a quick fix is to replace it with a new one.. (Advance Auto) or other parts store.

you need to get a diaghram on the firing order of your spark plug

wires, almost any autoparts store will give you the firing order for

your vehicle. if the firing order is incorrect the engine can sound

like its falling apart. the spark plugs also need to be gapped

correctly, they are not always pre-gapped or check the gap of

one of your old spark plugs and match the gap with the new ones.

good luck!

Cyldiner #2 not firing. I changed the spark plug wires and the spark plugs but it didn't fix the problem.


it sounds like you have a bad coil pack on that cylinder, chase #2 spark pulg wire to coil pack to find which coil needs replacement.

Replace the spark plugs and wires along with a distributor cap and rotor. Be careful to leave the old wires and plug wires connected to dist.cap, just remove dist. cap from the distributor and lay aside with plug wires on it then install rotor then new cap and proceed to replace each wire for cap and spark plug one at a time so you don't mix up the spark plug wire firing order. Cap laying to the side is used for reference purpose.

1989 golf turns over, new distribitor and starting


Did you use electric grease on these parts, the plug wires,and coil pack need this grease on there. It prevents moisture and wetness from rain getting within the components and causing mis-fire. Did it rain or was it cold outside to produce moisture. Grease is $2 for small pack. I just worked on a 95 VW, changed the cap,rotor button, spark plugs, cleaned throttle body, new air filter, fuel filter. His would run fine, but would cut off sometimes up to hours until the moisture dried. After tuning it up, he no longer has the problem. He goes through water puddles to see if it will quit, but it hasn't yet. Worth a $2-$3 try.

Car has a skip and not firing properly on all cylinders


Before you go checking parts that aren't there, unplug each coilpack connector one at a time with the engine running. After unplugging a coilpack you should hear the idle drop. If you unplug a connector and there is no change in idle, that is your problem cylinder. You can then check to see if there is spark by removing the coilpack and touching it to a ground on the engine, you'll hear it click. If you have spark, check the spark plug, if the spark plug is good, it's most likely a bad fuel injector. You can verify a bad injector by doing a resistance test after removing the connector. Injector replacement is a nightmare on these cars, but it can be done without pulling the plenum if you're mechanically inclined. Visit www.zcar.com for more help.

I have a 88 volvo 740 GLE and it wont fire.


The problem wont be your timing belt. you need to take out a spark plug plug it into your HT lead and check for a strong spark or even if there is a spark. check your contact breakers on the distributor as well
