Old plugs out, new plugs in. 17 Corolla 110k on factory plugs (they look pretty good, I think). Took 30 minutes and the dealer wanted over $300 

Are you running massive cables from the engine compartment or a battery on the trailer? I've got some forklift connectors for just this project. Although after like 16 years I don't think it's gonna happen anytime soon.Putting a winch on my trailer. Drilled some holes in a spare receiver and bolted it onto the trailed cross member. Should be good enough for now and may weld it another time. Need to work on wiring, using a small John Deere tractor toolbox should make it tidy. The weather is bad the next few days but should finish wednesday night.

That was me today at -13c plus the wind chill factor on a snowy driveway. The difference is, the starter on the F150 is just over a year old and the truck travelled less than 10k kms in that time.Mazda 626 wouldn't start last Saturday. There was a click so think starter first. Got one ordered and today it went in. I definitely prefer changing out a starter on my V8's. Even my Focus is easy since the starter is front and center. Piece of cake. The 626 has an intake support bracket in the way needing many combinations of extensions. Need to remove items up top to get to the two top starter bolts. Mazda manual doesn't mention that. Nonetheless got it done.

Haha, I’ve been in a similar position. I had just finished a dash out wiring harness replacement and couldn’t get the car to start, thought I must have wired the immobilizer incorrectly as it wasn’t lighting up when in the on position. Started pulling the dash back out when I realised I had also replaced the fuel pump and never put fuel back in the tank.Spent way too long troubleshooting no right trailer turn on a GMT900. Turns out if you're a complete idiot like me and reading the GAS layout for fuses when the truck is a DIESEL, you're checking the wrong fuses.
