Default no spark

I got a 95 bonnie that won't fire. Had low fuel pressure, changed the pump, now have no spark. Have no voltage on pinkl wire. what is the checklist I should go through to narrow this down.

Can you check for signal from the crank and cam sensors at the icm plug in? the book shows ins, and I get voltage at the cam sensor in port.

Check fuse #6 at the base of the passenger A-pillar. Remove the hushpanel above your RF passenger'* feet and look in there. Should be a 10-amp fuse IIRC.

I've checked the fuses and they are good. Where are the grounds to check?

It grounds against the back of the unit, to the bracket.

That'* a specific fuse that will prevent a 12v feed to the ICM pink wire. I'm not talking about the main fuse panel. These fuses are hidden where I described them. This fuse is on the PASSENGER side of the vehicle below the glovebox. Did you check all those? Most people don't even know they exist.

I checked all the fuses I could find with ign related, in drivers kick panel, pass side under the panel. still no fire, all other electrics work as far as I can tell, windows, seats, radio, instruments, fuel pump primes.

I am wondering if the key is bad, but the manual says the fuel system is cut when the key is bad. The security light goes off too. Is the igniton system disabled as well. Can the sec sys. be bypassed?

I also checked the icm for ground and it checked out, would that eleminate a grounding issue. does power run to the icm through pcm? would it do serious damage to splice a known powered wire to the icm to see if it will run?

Moose, was the key in the run position when you checked for power at the pink wire that connects to the ICM?

You can remove fuse #6 on the passenger side & test for power at the fuse block. One side of the fuse block terminals should have 12 volts with key on.

I checked for power with the key on. I'll check to fuse block for power and see what I get.

I have power to the fuse in run. Still nothing at icm. Knew had power because fuel pump was priming. Is there a relay between the fuse and the icm?
