Remote Starter Switch

[GhostWriter]

Recently, I posted a question in "Ask The GM Technician," then realized it wasn't the kind of thing a dealer would feel comfortable answering. My mistake.

 

I want to be able to perform a compression check on my 5.3, without a helper. With the key off, I want to be able to operate the starter, while situated under the hood.

 

Have a remote starter switch, from back in the day. Trying to think why it wouldn't work on a modern-day engine.

 

Is there a better way to go about this? Please, advise.

 

Thanks for your help!

My compression gauge has a schrader valve that hold the pressure. I simply install the gauge, crank the engine and then read the gauge.

With that said, I don't know why you couldn't hook up the remote starter switch that you have.

Ideally, you want the compression reading from one compression stroke, not multiples, which is pretty hard if you're not staring at the gauge.

 

OP, probably the easiest way is to extend the hose of your compression tester so you can prop it on the windshield and see it from behind the wheel.

 

As much as I do enjoy wrenching on my vehicles, the starter current draw compression test is actually pretty effective. Take it to a shop, and they probably won't charge that much for the test. That's what I've done with the last three used vehicles I bought.

Adding hose length will show a lower compression on the first stroke.

Thanks, guys.

 

I was thinking I could still crank my own engine with a remote switch, but you never know these days.

 

Also, I forgot about the first stroke method, & wouldn't it be nice to have your own scope for the current ramping?

 

Thanks, again, for your help.
