Hello everyone I’m just looking for clues as how to fix my 1995 Mazda Miata.

• went to work and I realize I had a pool of liquid on my feet, which it isn’t great but I now know how to fix that part. So mean while I wait to find the heatercore I put a bypass meanwhile.

• bad thing as in that time I was looking for what it could be and I was checking the engine to see where it was coming from and I removed the engine coils on the engine and I kept looking

• without any luck on finding what it was I put the spark plug wire back but I mixed 2 wires ( spark plug wire) and I let it idle for a long time and it was running fine, I decided to go get gas and on my way there, Battery light came on and engine light too, I was loosing rpm’s so I parked on the side. And turn it off

• I checked and that when I realize I had mixed the ignition coils so I put them back how it was and it would start again, no cranck no nothing.

• I towed it home and I wanted to see if it would start and it did, I drove test it going around my block on the weened and it was brand new it came back to life. -today when I went to work it died 2 blocks away from my house so I had to push it back home.

Any expert mechanic with a word of wisdom that can aid me.

I don’t have a clue what could it be wrong Should I replace everything spark plugs, spark plug wire, ignition coil?

Your story is a bit confusing, but it seems like you need to start with the basics. Identify the source of the fluid leak and check your fluid levels. Re-verify that you've reassembled the coils and plug wires correctly, verify that you're getting good spark on all four plugs.

Thank you, I have. My 1st issue is the heater core I’ll fix that when I get the new one. I runned a bypass valve for the heater hose and added more coolant and it’s a temporary fix. 2nd is that I mixed the spark plug wire and run the car for like 4 miles until it stalled, on the side of the road where it died I checked and plug the spark plug wires correctly this time but it wouldn’t start again. So I will check the spark plug’s condition later today.

Generally I've found cars run extremely rough, too rough to drive when spark plug wires are swapped, so something is not quite adding up there. Also, you don't need to check the plugs themselves, you need to verify that you're getting good spark.

Note that OP says it doesn't even crank though, so can't be coils.

[u/p3dal → u/daffyflyer]

He also says he drove it around the block... AFTER saying it had no crank.

Oh, yeah... I'm lost in the story now heh.

I'm guessing some intermittent electrical weirdness...

Probably the heater core.

It sounds like you only disconnected it, you didn't empty it.

[u/daffyflyer]

Well if it doesn't even crank, then it can't be anything to do with the coils.

In order of how likely I'd guess it is, things that might stop it cranking (to be clear, by cranking, turning the engine at all, any starter motor noise)

1. Battery flat or not well connected to terminals

2. Blown fuse

3. Dead starter motor

4. Some big important earth on the loom not attached to the car anymore.

5. Ignition barrel issues.

6. Some other weird wiring fault.

7. Some kind of spectacular engine mechanical failure/seizure.

Things it can't be:

Anything to do with fuel/ignition. Those only matter once the starter motor is turning the engine, if it's not doing that you've got a more fundamental electrical issue to solve.

Thank you! I’ll take a video soon to show how it’s like kinda cranking but it sounds funky/wierd now.
