Exclamation PLEASE ANYONE HELP!!! :(

I hosed my MK1 engine down, TOok the leads off to shove rag so the plugs dont flood with water.. All went well,

Then i put the leads back on.. And it doesnt go.. I cleared the little bit of water that was there out, put some WD40 and attacted the leads.. Now all it does is bang and miss and wont even turn over.

Iam pretty sure i may have put 3-4 on the wrong spark plug, tryed it, then swapped it back.

Still no go, I took out the plugs, they look fine. But i seriously have no idea.. Iam s00o0o stressed please helppp..



PLEASEEE Any ideasssss

It is probably still wet inside the dizzy and wires don't panic.
You can spray it down with something to displace the water. But mostly you just have to wait for everything to dry out. (last time it took mine about 48 hours to dry completely and go back to normal, 24 hours till it would start and run badly.)
Make sure that your spark plugs are not standing in water and that your plug wires match up with the correct cylinders.

Ive done the same thing over the years. =)

hope this helps.

I've experience misfiring/missing problems with just a very small amount of water around just the bottom of the plugs.

Try blowing air thru a small rubber tube at the plug bases, if you don't have compressed air at your disposal.

Firing order is 1-3-4-2

(BTW does anyone out there still index spark plugs anymore?)

Getting plug wires mixed up is nothing major. Just have to sort them out.
I never was a fan of putting water on an engine. period. But that's just me.
That's what rags and old toothbrushes are for. JMHO.
Grandpa.
P.S. Where abouts NSW are ya ?

Take off your distributor cap and blow it out with compressed air. I can almost guarantee there is water in there and that is your problem.

Try a new set of plug wires. I ruined a new set just like that once.

On a v8 engine, if you mix up the sparks it's possible to cause a spark at about 90 degrees after tdc, which will cause a backfire through the exhaust, or at 90 degrees before tdc, which will cause that cylinder to try and turn the engine backwards and cause serious damage. Or at 180 before tdc, and backfire through the intake and light your carburetor on fire. Fun times.

On our 4-cylinder engines, mixed up wires can do the following:
1: fire correctly, at about 10 btdc on the compression stroke.

2: fire at 10 btdc on the exhaust stroke. This could cause a backfire through the exhaust, but won't cause any damage.
3: fire at 170 after tdc, near the bottom of the intake stroke. At this point, there's probably not enough compression for gas to light, if it did ignite it would backfire through the intake--the way our fuel injection system is designed, that probably wouldn't cause any damage. If the gas actually ignites or is still burning after the intake valve closes, this will put some pretty extreme stress on your rod bearings and could cause serious damage. And it would stop your engine hard.
(4) fire at 170 degrees after tdc, at the bottom of the power stroke. This could backfire out the exhaust, but won't cause any damage.

None of these situations will do any harm to your ignition system.

Most likely your problem is water somewhere it doesn't belong, like inside your distributor cap or in the wiring to the distributor cap. It will dry out in a couple of days. If you're impatient, you can go through the steps like you would for any no-start situation: test for spark, test for fuel, test for compression. Your problem is probably spark, but you could have got water into the fuel pump wiring too, or knocked something loose. If you don't have spark, test everything in the circuit. I would pay particular attention to the wiring connectors at the distributor and at the coil.
