I'm having a problem with my truck not wanting to start. Turn the key and nothing happens. Short out the starter relay on the fender and the truck starts fine. I suspect my problem is in the clutch and/or clutch switch. A couple of days ago the clutch pedal bushing finally gave out. This is when my problem started. I was at the station fueling up when it happened. When I got home I checked the fluid level in the reservoir and it was a tad low so I topped it off, and then took a look under the dash only to find that the push rod was nearly separated from the linkage to the clutch pedal. I slid it the rest of the way off and what was left of the plastic bushing fell into my hand. Thankfully the parts store had a couple of them so I went and got a pair of them so I had an extra one on hand. The push rod and bushing are still wanting to slide off the little shaft on the linkage. I suspect that the new bushing didn't liked getting installed in below zero weather, and it may have broken an ear off when I snapped it in. I'm waiting for some warmer weather to try another one. Its not causing any problems with shifting, just starting. For the past two days I've been able to reach down and pulling the push rod over where it should be, and then the switch will actuate allowing me to start the truck. This morning that fix stopped working. No matter how tightly I pulled the push rod over, and how hard I pushed on the clutch, I couldn't get the truck to turn over. I even pulled the switch off of the push rod, and tried actuating it by hand while turning the key. No luck. Thankfully my driveway is relatively level so I just put it in neutral, popped the hood, turned the key on and waited for the GP controller to start cycling then shorted the starter relay out with my handy screw driver to get the truck started so that I could get to work. The screwdriver happens to be teh key to my redneck tailgate lock if that tells you anything about the condition of the truck....
So my question is, can anyone tell me what the pin out is for the switch that's on the push rod for the clutch master cylinder? I would think that there should only be 2 wires, but I'd be wrong. Just like every other automotive electrical connection, there are several wires connected to the switch. I'd like to unplug the connection and put a couple of jumpers in to verify if that my problem is this switch not closing correctly. If so, I will permanently short them so that I don't have to mess with it any more. Now that its -5 outside, I really would like to be able to start it from inside the cab.
Also, electrically speaking, are there any other switches that need to be made in order for the starter circuit to be completed other than the key switch on the column?
For what it’s worth, I’m talking about a ’93 F250 with the standard ZF5 transmission.
Thanks,
Mark
