Running a 1.6 IDI "on the bench".. what's needed from the chassis?

sweetjeep · August 5th, 2018, 17:10

Hey folks..

I came across a 91ish.. Jetta 1.6 IDI, non turbo car. Took it home and with the speed and effeciency of a guy who's wife was *ahem.. cough.. cough* happy with my great idea.. I pulled the motor and trans.

The rest of the hulk is headed to the junkyard immediately, same with the trans.

This being a non-computery motor.. is there anything I need from the chassis to make the motor run on it's own? As I recall, If it has fuel and I apply power to the starter, the motor should run.

Am I right?

And.. uhh.. I haven't thought this car until RIGHT NOW.. how would I shut it off?

Remember.. "wife powered haste"

thanks!

12v to the fuel solenoid, starter and starter solenoid. Power to the starter solenoid is only until it starts.

Being an IDI, apply 12v to the GP buss, for about 10 seconds, prior to cranking. If everything is good, it should start. Disconnect the fuel solenoid to kill the engine.

Perfect.. thank you!

I don't know what the GP bus is.. but I'll figure that out next.

Much appreciated!!

If the speedometer has a tach, pull that and sell it. You should pull the fuse panel as well since it's a quick job and might come in handy with whatever you decide to do with this engine.

Thanks! I DID save the big ass cable that turns them on! If you don't recall (and something tells me you DO) there is a big cable that went to the dashboard where you pull out this lever to activate the.. I assume.. relay.. to fire them. It's absurd and even in 1991 this has to be the only goofy car that did this!

Burn_money: No tach, sadly, but thanks for the tip.

The next destination is as a mockup engine for an M38 (Flat fender Willys, Army jeep) then probably will become a motor for a generator.

My guess is that you're referring to the "cold start knob"... cable-controlled advance of the pump's timing and idle speed, to aid in cold-weather starts and warm-up.

The glow plug system itself is entirely electronic... since 1979.

That does makes vastly more sense. The kid I got the car from declared it the glow plug activator. In this case the dash has no (functional) indication that glow plugs are/were active... I just went with the delightfully awkward "I guess this is how this silliness works!" After all, it did have those awful 2 part seat belts and a radio that doesn't turn off (classic old VW trickery).

I would not expect a 91 Jetta GL diesel to have a tach. Even the ECO-D cars didn't have a tach. Finding a CE2 cluster with tach for diesel, from a US import, is I would say impossible.

The lever in the dash did not activate a relay, it moved a lever on the IP that advanced the timing of the pump a little so that cold weather starting was aided.

Diesel cars in the US all did

I would bet it worked too didn't it?
