And what if hypothetically that wasn't an issue.

And I had to dump coolant down the upper hose to get it to start cycling coolant and I know there is a better way haha
First off, I never use bosch.

NGK Coppers work great.

Alright, well, now I was adding some more freon (with UV Die) to the AC system in order find the leak, and then all of a sudden it just sprayed all the freon out of the side of the dryer. Im talking about the little spot where the lines connect. I'm guessing there was some kind of pressure release valve there? The Guage on the freon bottle said it wasn't even full yet. Was there air in the system? What happen? Lol

So replaced starter last night, started right away this morning but it wouldn't start after work right away. There's a click and all the radio and such go off. Then randomly starts. When it does start it's pretty instant.

Edit: could it be the key wearing out?

Check your battery connections.

Those are good. Just re-connected and ox-garded them last night after I did the starter.

Interesting though I pulled back on the shifter handle and it started. I think my new NSS needs realigning. I tried the reverse light trick but they stayed on at both extremes. Maybe I didn't tighten the adjuster bolt good enough either. I'll have to double check that when I get home.

Edit: Don't think it's that...just tried starting it and it would start for anything, tried swapping starter relay for fan relay. Only worked when I jiggled key up and down...the cylinder can't be bad can it?

anything available at canadian tire or napa really, there isn't many more places. we also have carquest but i never went there.

sometimes amazon.ca has good prices and free shipping so I'll get stuff from there. for example my RE leaf springs I just bought were from amazon, shipped within canada, so much cheaper than getting from RE themselves.

i'm in quebec city, so about an hour and a half away from trois riviere. val dor is really up north, I've never been there. i think it's almost the same driving time as new york or toronto ~8-10 hours

Not that I'm aware of, sounds like it's trashed now.

Keep it simple, the best electrical connection is: clean & dry.

Check the function of the ignition switch with a DMM, is the connecter fried?

when I look it up, it seems that a lot of AC compressors have a pressure release valve, I'm guessing mine has on on the side of the high pressure line by the dryer. Here's what I mean, the dryer has what looks like four connections, look at pic. One for the low pressure switch plug. One on ethier side for the AC line connection. And the last one, I'm guessing is the pressure release valve. That's where it sprayed out on mine. It's the closest one seen n the pic below, opposite side of the wire plug
