Well guys as I said in my Gtp thread I was getting the truck back out, now I like to think I know a lot about tbi 350s, and I know them better than 3800s, but I am just swamped on this part of the truck, im going to ask it here any way idk if any of you guys have messed with 1990s tbi 350s. So here is what I have to say, and I wanna see if you guys know what this problem could be. Any way first of I was driving the truck around one day, then I decided to put my 88 gauges in, so put them in, then I got smoke out from under the dash, then I put my 91 gauges back in and they worked, but now the truck is getting no spark, it turns over, fuel system is working good, but no spark idk what the he*l it could be, I think I found the wire that burnt under the dash and I fixed that!?!?! So now I am just stumped! If any body knows what this problem could be any help would be appreciated!
