Chevrolet S-10 Blaze Stalling All the time

“I’ve got a 97 S 10 Blazer which is dying on me all the time. I took it to be scanned, but there were no trouble codes. What should I try next?”

Well, theoretically there could be LOTS of things wrong. But since there are no codes, I’d start by checking the fuel pump and pressure of the fuel system. That vehicle has no sensor for fuel pressure, so the computer doesn’t know what the actual fuel pressure is. So, if the pump goes bad, the computer doesn’t know and can’t set a trouble code. And on that Blazer, if the pump has to be replaced (and the fuel tank removed to access it), be SURE to check the connector and wiring going into the top of the fuel tank to the in tank pump. That connector and wiring often goes bad. I’ve been burned before by not paying close attention to that connection and had to do the whole job over because of bad wiring back there. It’s a simple job to check once you have the tank pulled, and no one wants to do that job twice.
