Spraying that stuff generally does not work. Remove each wire one at a time and wipe down with as clean dry rag. Then with another rag soaked in either silicone spray or wd40, wipe it down again and replace it. Also...check the inside of cap and rotor for any moisture or carbon tracking. If tracking, replace. If wet, dry it out and replace it.

My 1997 GMC 1500 will not run or start in damp weather I seems to be getting fuel

You need to get some wire dry spray and spray all your wires and the ignition cap etc. You may have some bad wires or you cap has a crack.
Try the spray first see if it starts and runs.

Ramdom/Multiple Cylinder Misfire Detected

The normal causes for code 300 are ignition fuel or engine mechanical.
The spark could be weak at the plugs, the fuel system could be lean or the fuel pressure could be below the required limit, or the valves or other components could be affecting the performance.
I would start with replacing the plugs and fuel filter if they have not been replaced in the past 12 months.

Car doesn't start after rainfall...starts OK when dry...What could be the trouble?

Change your spark plug wires. Insulation breaks down and allows voltage to leak to ground. Make sure to route the wires same as original. Quick check is to spray WD 40 on the wires when wet as it displaces moisture. If car starts, get new wires. If you have a distributor cap, change that too.

My 92 f150 won't start after it rains

Try changing the spark plug wires, if that doesnt eradicate the problem, try replacing ignition module & Distributer cap (if applicable). the problem is you are getting moisutre in there whenever its wet outside

Washed car...lift hood to wash started, then sputtered and cut off. It looked like it was out of gas, so I put gas in it. Now it starts, but is skipping and sputtering and will not go...water...

Yeah, you sound like you have water down in the plug/wires. You will need to dry out the wires from the plugs to the coil pack. You can buy a solution spray to dry these out faster than air dry. But it will have to be dried before it runs good.

My 97 vw jetta won't start when it rains

I would check your spark plug wires, when it's been dry out, start the car and with a spray bottle, spray the plug wires and see if there is any difference, also the coil wire. The smell is most likely from the catalytic converter. Any check engine light?

My 1996 ford taurus will not crank or start.i washed the engine down and after that it didnt start anymore. all lights turn on and the battery is new.

go to a local jobber parts dealer like Napa etc and ask for quick dry or wire dry spray.. mention these two names and if the employee has a clue of what your talking about he will sell you a can.. ususally about 5 bucks. then take it to your car and spray the distributor and the spark plug wires generously.. this will fix you problem gaaaaaaaaarantied

I relaced the coils but still see spark jumping under the hood

YOU want to stop the coil wires from jumping ,,,,apart from replacing all leads etc ,,all you have to do is to SPRAY IT ALL WITH hair spray
Yes hairspray but let it dry for 1/2 hr before starting
as h/spray is good for all wiring . you can also spray HTLeads Plugs and Battery term.

Engine compartment got wet now it is missing and

Let a fan blow in the engine compartment for a long while. More importantly, the ignition wiring and plugs need to be dried out. Trace spark plug wires back to their source.Use WD 40 or a wire dry spray (auto parts store). Unplug spark plug wires and spray. Unplug ignition module wires and spray. Unplug all electrical plugs and spray. Also use a air dryer to remove moisture, and to dry out wires.
