The Sy has been out of commission for about 2 years now. Left in the garage for some time due to it not taking priority over other stuff. Back now trying to resolve some issues with it.
1) before it stopped starting it had a stumble to it (during idle the rpm needle would jump around just before it would stumble, then stall with a cel) I have an obd1 scan tool and was going to troubleshoot that issue and then it stopped starting (it used to click click click before starting and now nothing).
It always had the click before staring since I bought it (I'm like the 5th owner on it).
So I wanted to address the starting issue before going into the main issue of the general running problem, since I could at least move it before.
2) Purple wire... seemed burnt being so close to the DP, was not receiving voltage off of the post it connects to on the solenoid when trying to start it (12v) . Removed that wire and spliced in a larger 10g wire and butt spliced it into the original.
*The failure to start thing really came out of the blue... just one day nothing, first response was battery since it had been sitting so long... new battery nothing, same.
After splicing in the new wire I am still not receiving 12v to the starter solenoid....
I double checked the wire and connections...same.
I was able to jump the purple wire post on the solenoid over to the hot wire and turn the starter over so it seems like the solenoid is engaging with voltage applied.
Decided to check the safety switch on the center console on the shifter to check for 12v, when I turn the key over I still have no voltage off of the yellow wire on the safety interlock...I made sure it was in the park position several times but still not seeing 12v on it.
I was really hoping it would just be the safety switch was NG.
Next steps in the book is to check the yellow wire for shorts to the ignition inside the cab, bit I can't see that being an issue but I can't just cancel it out yet.
3) Fuse box, I checked the fuses for the ING (odd there are 2 sets of ING receptors but it seems like the one outlined in white is not used?)
All the fuses are okay inside the box (hazard, ECM, ING) all are intact.
* the reverse lights do light up when positioned in reverse...
Guys, I am out of ideas here.. my next step is to find someone in the Portland OR area to help fix or pay $$$ to get it fixed unless there are some other ideas I can try.
Thanks in advance!
