No ign fuse
Bought a 91 camaro and I?ve been working on it here and there. Got the 86 steering column in. Realized it was missing some fuses and most of the fuses has a dark texture to it. Swapped out the turn b/u fuse and turn signals work now. Just gotta figure out the VATs and everything else. I went to bypass the starter relay and it still won?t crank. Temp gauge turns when I crank the key so something has to be right. Fuel pump primes too. It?s missing an IGN fuse and I?m just wondering if this could be the culprit to why it won?t even crank. Previous owner said the ECM was bad so I was going off of that, bought a new ECM. Checked the ECM fuse after the fact and it looks blown too. Just wondering if the IGN fuse missing and the VATs/ECM fuse looking blown could potentially be the reason why it won?t crank after bypassing everything correctly. Probably just gonna swap every fuse. I hope the starter/alternator isn?t toast too but I can get them both rebuilt for about $10 anyway. Any thoughts are welcomed. Thanks.

The IGN fuse has nothing to do with ignition or starting.
However you can use them for low draw accessories.
Connect a voltmeter across the M terminal of the starter and battery.
Make the leads long enuff to take the voltmeter into the cockpit.
Under normal circumstances, when cranking you will see about 9 volts on the meter.
On the occasions the starter fails to crank note the voltage.
The voltage will tell you what direction to turn.
If it's about 12 while you are trying to crank, but the starter is not turning - the problem is in the starter.
If it's under 8 while trying to crank - the problem is excessive resistance in the starting circuit or an open circuit which sounds like the problem.
Therefore if it is in the starting circuit you can move the probe you applied to terminal M at the starter, to the positive terminals at the solenoid, then keep moving up the line till the problem shows itself VIA increased voltage.
