Hello! I all of a sudden have no spark out of my 94 Metro coil. I swapped motors (never even touched the coil) and now when I go to get it fired back up, there is no spark coming out of the coil wire. When I first went to start the car, I blew the main 60 amp ignition fuse because I didn't have the starter wire grounded properly. I replaced this and all is well except there is no spark. Could I have blown something else too, or could my coil just have taken a shit? What should I look for? Could one of those little black fuse box things that hang on the front of the coil have gone bad? Any and all help is greatly appreciated!

Alright, I went to the junkyard and picked up a coil and the car still has no spark. So I don't think its the coil causing this.

I just put a 1990 1.0L in the 1994. So really, I put the same motor back in the car. The only thing I had to switch was the intake manifold and throttle body and the distributor if I remember right. Anyway, I never even touched the coil or any of the wires that go to it, so it should still work.

Is there anything that could have blown?

OK, 1st thing is remove ALL of the spark plugs (so it cranks over easily + other things)

Next remove the high voltage (spark wire) going from the coil to dist cap at the cap end.
Hold it with a small gap away from the head and crank it over (i.e. try to start it)
Did you get any sparks?
If yes, then you've got a distributor/rotor/cap problem.
If no, then you've got to look further.

Next grab a voltmeter (set it on dc scale), turn on ignition and check voltage from batt- to coil + terminal.
Do you have +12 to 13vdc?
If yes, then you've more than likely have got a triggering problem on dist pickup or wiring going to it.
If no, then you need to chase back that wire (eventually goes to ign switch) and find out where the +12vdc voltage died.

I'm tired of typing, so do the above and call back with the results
('sides I've got no hot water to shower with so I've got to fix water heater now)
We all have got problems.. :)

Could a vacuum line somewhere thats not hooked up correctly cause this at all? For instance, would the coil somehow know that there is no vacuum going to the MAP sensor cause this?

This is exactly the problem I have in my Metro.
I have a 93 metro that I bought a remanufactured long block from, got the engine in ( a long story), drove it for 63 miles before all three bearings spun took it back out, sent it back to be fixed, got it back, took it apart, sent the head to 3-Tech got it back, put them together, put them in.... and no spark from the coil.

I took the coil out and replaced it... no spark
I took the relays out and replaced them... no spark
Tried new ones in both .... no spark!

NO SPARK! NO SPARK! NO SPARK!

So I will try the advice on here and see...
But I woulld like to know if it worked on the 94 Metro.
I don't have alot of time during the week, so I might have to wait til Sunday.

when you turn on the key do you hear a little buzz for a few seconds from the fuel pump.

The first few times I did but during tohe starting it backfired through the intake a couple of times... though it all I didn't notice it but... after awhile I noticed that the fuel pump isn't turning on when you turn the key on.

Also for some reason if I keep the battery hook up, after a day or two it is completely dead. If I unhook it from the car It will be just as good when I unhooked it even if its two weeks later. Do you think it might be the same thing creating the problem?

cheak the wireing to the small fuse 15amp i think near the relays under the hood, my 92 had the same problem no spark and no fuel pump, turned out it has the wire going to that fuse had coroded.

Your battery discharging behaviour matches the exact symptoms of something shorting out somewhere. Quite possibly the ECU is being denied power or may be cooked. Start tracing your wiring and fuse panels for shorts. Only after you're confident that there are no wiring problems should you try another ECU (installing a new ECU in a vehicle with defective wiring isn't very good for ECU life).

Here's some info on how to trace for defective circuits:

Your loss of spark suggests to me either ignitor failure or a problem related to the ECU (coil wiring, ECU, FI fuse, ECU wiring).
