You mentioned that when you sprayed a volatile substance like starting fluid in the throttle body it wants to start. That is why I spoke of fuel punp. I would not be able to guess on someone else's truck. If it was my truck, I would install a fuel pressure guage(40 bucks at Autozone or auto parts store), and when it wouldn't start I could see if it had fuel pressure. Usually a coil pack or plugs fouled or bad will start but run terrible all the time. So I would use a scan tool and fuel guage to see whats up. A code is usually present on an electrical no-start. Also after it starts, the fuel pump has charging voltage(more electrical available) and that may be enough to get it going.
No, the way you described it, it didn't sound like a miss or no spark.
You have to check it when it is happening, fuel or spark may be missing, and all I know, is the words I am reading.
If I was there, I would check it for spark and fuel the way I spoke of. With 80,000 miles it could use a new fuel pump and plug
s also. I would like to tell you to get a ride and leave it with someone. To be sure. OK Joe The truck fuel pumps did fail quite a bit and that I know. When it won,t start for the 15 minutes, sniff or look fur gas in the part it is supposed to be.
