Well, I still have been trying to figure out whats going on with that light flashing at random while driving. I had previously tried cheking the strip fuse, listening to the relay, ohming out the gp's and taking a reading from the temp sensor. Other than the light flashing the car seemed to start & run just fine so it hadnt been a pressing matter so much as a nuisance. Well...
The light has progressively gotten to the point its always flashing now. The car has been beginning to run a lot rougher at first startup, and takes a bit longer to start. Granted there's been a hefty cold snap here the past week. I went to start it this morning, it stumbled and coughed and wanted to run but wanted the starter to keep it spinning for a few seconds the first couple of tries, 3rd try it started, ran on 1 or 2 cyl's, and just touching the accelerator killed it, same with 4th and 5th try, just by the way it started the very first time it appeared to me right away the gp's had quit. I cranked up the dash idle knob and got it to hold itself once it caught (6th try) it ran ragged but it was firing on all cyl's, after a few minutes I put the knob back and went to work. It was a little stubborm the first try going home, it caught as normal the second try though. Now, I got aggravated and decided I was going to find this bug once and for all, so today I checked battery volts w gp's on and off, had a 1 volt difference. I removed, wire brushed and installed the strip fuse, cleaned it's mounts, & removed/cleaned the main power lead and stud. I removed engine harness from gp block and rang ohms from pins to block thru gp's, rang ohms from studs on gp's to bases (with wiring unplugged), rechecked temp sensor, verified voltage at all gp pins on module when relay is on, verified relay comes on and cycles out (approx 45 seconds) with several key cycles, verified loaded voltage at module with gp's connected, re checked ohms on everything with a different ohmmeter....and can still find nothing wrong out of the normal.......wheres that dang sledgehammer when I need it.....I'm reaching the point I'm about to replace every single part of that system......
