Been reading a lot of threads on people having TBI problems lately. Yesterday I drove 50 miles each way to get new tires put on, come home, move the truck around the yard a couple times, no problems. Start it up this morning, walk 1/2 way to the garage and truck quits, Hmm that's weird. Go back won't start turned over good but no try to start. Fuel being squirted out of the injectors, more that 12 volts at battery, 12 volts at fuel pump, poured a touch of gas under the injectors, no change. Did have a gas smell initially at the front of the truck. Hook up the inline spark tester to a plug has spark. :thinking:

crawl underneath and the wire that goes from the fuel pump to one of the plugs on the firewall that has a fuse in it, the wire loom around that is melted for about 2 feet, I can see I need to move it more to the outside of the truck so it's not so close to the exhaust, get ready to do that and search the wire for problems and heavy rain begins, YAY. So that is where I stand right now... I did check the fuse and it looks fine and continuity test shows good.
 
Like I said Ina different TBI, no start thread. All it takes to damage an ignition module is an errant static spark, and it's done.
Not saying that's what's wrong with yours, but, it happens, alot.
 
found a pinch in the positive wire from the fuel pump to the plug on the firewall, wire loom was all melted, ground wire loom was also melted a bit, no issues with the wire. Replumbed both further away from the exhaust and put new loom on, tested the fuse on the firewall it tested good, put a new one in just because and it now fires up quicker and better than it has in quite some time. :D
 
^That ignition system flow chart needs to be amended. All answers are supposed to end with "Install LS based platform".
