Lost spark

[HEATHSS79]

Hi, could someone help me please?
My 94 vr ss was running fine when I parked it up, but when I went to restart it the following day it refused to fire. I went through the typical process of elimination, checked for fuel check. Then checked for spark nothing! While going through the check process I found i wasn't getting spark from the coil. So in the process of finding my way to the coil I stumbled apon a black wire coming from the + side draping down onto the bellhousing, where is that wire meant to go please and is that why ive lost spark?

Do you mean it's a positive electrical connection? And what is the unit that it is connected to? When you said black I straight away thought it would be an earth connection. Are we talking V6 or V8? Sorry it's only questions and not possible solutions from me at this stage.

Yes it must be a positive connection, it stems off from the same connection point of the coil as the red cable that goes to the main harness on the firewall

Sorry, and it's V8

Positive side of the coil goes to the ignition module and EFI relay, should be a red wire, don't know why there would be a black one there. Is it just hanging loose?

I'd look at the ignition module first, swap it for a known working one and see if it starts.

Positive side of coil is Red wire to EFI relay and also there is a wire ( colour not shown in schematic ) to the noise suppression cap.
The negative of coil is a brown wire that goes to the Ignition module and the tacho and also has pigtail for a tacho signal at the left strut tower.
Hope that helps.

More info:
YE1 is a push on ( spade ) connector - red wire.
YE10 is an eyelet connector held on using a nut - brown wire.
The crimp on the YE10 connector to brown wire can corrode and cause
no-start conditions.
Having said that ALL crimp connections can fail eventually !

Thankyou so much for your assistance, I will check it out after work and get back to you with my outcome. Thankyou

Funny enough the YE10 hasn't broken at the crimp connector, it has broken about 100mm away from that. So would I find the other part to that wire amongst the main harness along the firewall?
