Ok I don't know if there is a thread out there yet for something like this so I'll try to start one.
When working on your barley or non-working truck and you're having an issue that makes no sense at all and you have done all (or most) of whatever diagnostic procedures it can really get under your skin.
Like doing everything right on the first two dates and you still end up going home to Miss Michigan on the third date. You followed all the instructions, did everything in the correct order and you're still not getting to use your dipstick. Usually you ditch the b*tch and move on, but it would be a shame to do that to a beautiful OBS. Post your stupid fixes to problems that you've solved in the past.
First to post:
I had to put a new motor in my truck when the last one took a . I was was in a big rush and I ended up pulling it into the garage, taking the hood off, and pulling the old motor and putting the new one in in only a couple of hours. When I hooked up the battery some lights on the dash lit up very dimly which was odd but whatever, I needed to know if my "new to me" motor was good. I started her up, ran fine, went to shut it off and nothing happened... truck still running. I thought I smashed a wire or pulled off a ground somewhere, I was pissed. So I start checking wires everywhere, all looking good. I looked up wiring schematics on all data and pulled out the multimeter and started the seemingly endless task of checking any and all wires that could be backfeeding to the ignition, nothing. Checked ignition switch after recommendations from the techs at my work, it was good. After my last attempt to swap various parts back and forth from the old motor I was completely as a loss.
In the end I was putting the hood on to push the old ***** out of the garage to work on another vehicle when I noticed the connector from the hood light wasn't there. I looked around for about 10 minutes and realized the MAP sensor was unplugged also.
Solved:
I had hooked up the MAP sensor lead to the hood light power lead (which are the same exact shape and size) and it was feeding it power because the hood was open/off. Nowhere in alldata did it say that the map sensor somehow fed back to the ignition.
This was a huge pain in my ass and I have never heard of someone else having this issue. Hopefully this will save someone some time and headaches.
