So my blazer stalls while I am driving. The motor just shuts off. It has happened at 70 and it has happened at 30. Then it takes a while to restart. The motor will turn over but it wont start right away. I have checked the alt. And I have put a new battery in. I also have changed the fuel filter . I check the fuel pressure and it is at 60 and left it off for 15min and only dropped 1 or 2 lbs. When I first start the truck in the morning it starts and runs fine drive 18 miles to work let it sit all day. If starts fine then between 7 and 12 miles it dies. So my brother in law and I think it could be the spider fuel injectors but before I spend 300 plus and all that time need a couple of opinions. Thanks in Advance Al

 

After it stalls it will turn over but wont start, but if I pour gas into the top of the carb it will start and run until I stop pouring the gas. Also there are jo fault codes.

 

Had a similar issue. Truck would randomly die after being driven a bit. After a few minutes, it would restart, but do it again a few miles down the road.

I investigated, and ended up dropping the tank. This is what I found:




The harness for the pump was melting. When it got hot, and the resistance went up, I'm guessing it would lose connection, and stop the pump, stalling the truck. Once it cooled off, it would run again for awhile

Edit: I was cheap and lazy at the time lol. Instead of replacing the sending unit, I scrounged up some female wire lugs, crimped them onto the harness wires, and rolled like that for probably four years without a problem. I just replaced the sending unit last year
