Chevrolet Repair: 197 chevy blazer fuel issues, chevy blazer, check fuse

Question
i just recently changed the fuel pump on my 1997 blazer.after changing the pump i did the normal priming procedure by turning the key on for a min b4 trying to start it to let the pump push the fuel back through the lines.the blazer started just fine. i however did not insure all the quick release connectors was connected and after a short time it came lose and killed the blazer.i found and the problem and checked all connections at that point. once again i did the pre start prime. the blazer once again started fine. the next day i go out and it no longer wants to start what could it be

thank you for any suggestion or help


Answer
Hi Chris... can you hear the pump turn on... do you have fuel pressure at the rail...check fuse and relay...is it flooded. when you reconnected the line could it be pinched closed...if you have pressure at the fuel pressure test connection under the hood, do you have spark...do you have enough pressure...that is where i would start looking....hope this helps
