Stuck!! No crank ! LF some input and help !

5AB,

I like the idea of a backup for the starting circuit. Having said that, I would have had the plenum off and the starter out w new contacts installed them button everything up by now. At the end of the day,'u should still do the "rebuild" on the starter anyway. My $.02.

I agree with you 100%. I've been a little strapped for time during the move and all but if it wasn't for that I liked would've had it apart already. What actually stopped me from doing that however is when I jumpered to the battery direct and it cranked like it was new. i could very well be wrong In dismissing the starter after that but it was the reason I initially assumed the starter was fine. Also I have never had a non crank since the day I picked up the car and in my experience I have witnessed starters do this once in a while before needing replacement. I do have new wires to put on so hopefully it's fixed and I'll go in and clean up the starter with whatever I can do while im in there


It's 1130 now.. Heading home putting kids to bed. Getting a coffee and time to hit the garage.. Here's the plan based on dynomites write up ..

Maybe the final update ...

PROBLEM SOLVED !!!!!!!!!

Ok so before I even began the relay mod.. Since yesterday I had been wondering how the purple wire end coming from the clutch switch would trigger the relay to put power through from battery to solenoid. Why? Because I was testing it with the volt meter and when key forward I was getting nothing from the starter relay at the kick panel. I was confused by this and forgive me for asking so many questions.. Long story short I pulled the manuals out from the boxes in the shed and found the diagram. I had a connector that didn't have the same color wires as the diagram and I was really confused. I looked again underneath and was convinced at what I thought was the clutch switch. After googling the switch I found an eBay listing where it mentioned it was for all years of the c4. It was nothing like what I thought was the clutch switch :/

So in a beautifully edited photo by me .... and yes I believe most of you are aware what the clutch switch is !



I tested the switch plug with my multimeter and no change with the clutch depressed. I cut the wires, tied them together .. Turned the key and she cranks. Thanks to everyone for chiming in and hopefully this may help at least one person in the future. I figured since it was a button that was depressed by the clutch pedal that it was the switch. Clearly I was wrong. The actual clutch switch is higher up and the wires are sheathed in black so the colors were also not visible to me.

On the bright side I feel much better, I bypassed the key resistor and the clutch switch and have an emergency wire still above the battery tucked away and I have some more experience with a multimeter to boot !

And.......this is a 94' ? Prolly note that this is a 94' in above post

I did make my friend stick his head under there and take a look.. He saw the white switch.. Whatever it is and thought it was it too lol. Anyone know what that other switch is for ? I have a relay all soldered and ready to add if need be. Now to pull the plenum to do the wires and coils and I'll clean up the starter too while in there. Before I ask I will search on possible parts to rebuild it or get it as new as possible when I do take it apart.

Marc Haibeck describes the electrical schematics and further identifies that "in 93' GM modified the starting circuit which reduces the load on the clutch switch from 30 amps to .2 amp".

See Starting Issues by Marc Haibeck

But you are saying that on your 94' the Clutch Switch does not close so GM must have put in a smaller capacity clutch switch given there is only .2 amp on that circuit or Could it be a mechanical issue with the Clutch movement not closing the Clutch Switch??. I did not install the Relay in my 95' since it appeared GM solved the Clutch Switch issue???


Convince your friend to remove the Clutch Switch so you can check it out since you no longer need it
