Where to find Cold Start Time Switch? Aftermarket Alternative??
Having a hell of a time tracking down the cold start time switch for my '88 3vze. PN is 8946220010. Apparently it was only used for part of 87-88.
Toyota says it's discontinued and they don't have one in the country. Napa, Autozone, O'Riellys, and Advance can't find one. None of the salvage yards here have that year pickup.
RockAuto shows these other part numbers for the switch:
AIRTEX 1S5245
TOYOTA 8946220010
CARQUEST 5356503
WELLS EDS13
Few questions:
- Does anyone know a way to lookup what vehicles this PN came in besides the truck?
- How can I find an aftermarket alternative?
- Could I run the later '88 CSI time switch with a new pigtail spliced in? The plug is different.
Mine looks like this:
Later 3vze part looks like this:
The catch is I need it before Friday because I just sold the truck to a friend. We're moving on Sunday and I wanted to replace it for her before I go.
PLEASE HELP! Anyone have one they can overnight me?
I dont think 88 is year specific for the Timing Switch. I had to change mine out on my 88 for one that looked like it in the boneyard and it was out of an 87.
Going by memory, the voltage requirements are the same for other year models. Don't quote me...I'd have to go back and verify. If I'm correct, then yes....you could switch out pig tails. Failing a replacement, I have ran my '92 without a functioning CST switch for years. I think I've only had one or two times where it took a minute to start, but that was when the outside temps were down in the teens.
What is the difference between yours in the newer models?
The plug style is different. Don't know if the function or threads are different.

Yea, it's an 87-88 specific part from what I've found. Late 88 and onward 3vze's have the style in the 2nd photo I posted with the black connector.

Anything below 30 degrees and I have to crank it maybe 20-30 times before it stumble starts. It's been in the teens all week here so it's taking a while. Starts right up after it does the initial fire.
Mucci, did you see my post on your other thread about making sure the timer switch is properly grounded through the block?
ONE of the differences between the CSI circuits is that before 1988, ONLY the CSI timer switch controls grounding of the CSI. From 88 and later, the ECU also takes part in controlling that ground. (see my post regarding that).
Just bought a used one off a guy on eBay. Thanks though.

Thanks, good to know. I didn't check the ground but the resistance between the pins of the current switch was 3x what it should be. I'll make sure to clean up the threads before installing the replacement.
