Motor cranks, won't start, no spark

[Killee]

I didn't disconnect the battery and was removing the wires from the starter, ended up sparking one off the frame.
My motor cranks, but won't start. Checked for spark at the coils and found none. Checked all fuses (that I know of, three boxes) and found none blown. Anywhere else I have fuses, or any in particular I should check.
Any ideas on why I wouldn't be getting spark still if it isn't a fuse?

Fuseable link probably burnt. Check those.

I gave them a glance over, and they looked fine. I always thought if they went they looked obviously burnt/melted through.
Do I have more links other then the two branching off the starter and the one from the battery that I should check?
Think it is possible the ignition module got fried, and is there a way to check that besides pluggin a new one in

Here is a place to start:

If there's no spark, check to see if the ignition control module is getting power and ground (with key on, use a digital volt meter - the harness is one of the 2 wire harnesses going into the ICM - I belive its the one that is on the same side as the large multiple wire harness). If it has power and ground then check to see if it has a crank signal. The crank signal arrives to the ICM via the other 2 wire harness (IIRC: 1 wire is purple and the other is yellow or maybe orange - I believe this is the 2 wire harness that is on its own side). To check for crank signal: while someone cranks the engine, measure voltage across the 2 terminals on the wire harness. Use the low voltage AC scale, you should get a fluctuating low voltage AC signal (the analog reading on a digital volt meter may be easier to see then a rapid changing numerical readout). If no signal is present, suspect either a bad Crank Position Sensor or faulty wiring between the crank sensor and the ICM.
-This applies to 91-93 dohc engines. I cannot say if it applies for the 94+ because they have more than 1 crank sensor and I do not know if the wiring/signal is the same.

FYI - the large harness going into the ICM is used by the ECM to manipulate spark timing and get rpm data. Also, the signal wire for the dash board tachometer is in this harness.

hope this helps you out, or at least gives you a place to start looking

Good luck,

For anyone who is interested, it turned out to that my ICM to Crankshaft sensor wire had melted together in the middle. Found it grounded out with voltmeter, so pulled the wire out and it was melted together.
Starts fine with some new wire.
