I finished painting my hood and flipped my thermostat to run a couple degrees cooler. I was getting up to 201-203 driving for 30 minutes in relatively cool weather. After starting the truck a few times while burping the coolant I was ready to pull the 4Runner out onto the street to drive it for the week.
Turn the key...click...********. Looks like cleaning all my grounds didn't fix my intermittent starting issue I have run into twice now. Back to the internet I was pretty sure it was time to replace the contacts in my starter.
Pull the starter. Replace contacts. Install starter. Turn key. Click. ********.
Check voltage and find I'm only pushing 11.5 volts. Charge battery overnight. 12.5 volts. Turn key. Click.
Bug GF to come turn the key so I can take some voltage readings to the solenoid etc. "just press this button and turn the" VROOOM!, engine fires. Repeats twice. Then won't start again.
Additional reading thanks to the toyota Guru 4crawler and I start wondering if the very poor choice of wire routing from my ECU to the starter solenoid is causing a voltage drop and I'm not quite getting the juice I need. So tonight I cut out the wire from my harness that runs from the ECU to the starter solenoid. For once I had tucked a wiring harness away and taped it up nicely. I cut it out and removed about 8' of unnecessary wire, cleaned all my contacts, turned the key, and she turns over but won't catch. sigh. A couple more tries and back to just hearing the starter solenoid click. Check voltage. 12.1 volts. Connect portable jumper and get it to turn over twice more before going dead again. Crawl back into the passenger kick panel and notice my carpet is wet. Upon further inspection it appears I took on a good bit of water while my hood was off, and a large portion of it was directed right down my wiring harness into the ECU. woops.
So I finished the night by pulling the back off my ecu and bringing it inside. I'll let it dry out for a couple days and try it Sunday before having to bailing town for work next week. One of these days I'm going to put some miles on this donkey.
Still feel like doing a 3.4 swap @Nikkshepherd?
I still recommend it. Just don't take your ECU swimming. Assuming that was my issue...
