I have a 1995 Chevy Blazer I have replaced the fuel pump recently also the fuel injectors I tuned it up a few months ago. I was driving down the hwy today and it started feeling like it was hesitating somewhat. When getting off hwy sitting at light it would not idle steady it would idle up then down. Then the Service engine light came on. Went to get my check cashed came out and had to put my foot on pedal to get it to start. Went into a store for 1 hour came out and it started ok and ran good for about a minutr and Service engine light lit back up. I also noticed the exhaust dont sound the same just a little louder. I say its the catelatic converter what do you all think it is?

The cat may be running inefficiently due to a tune problem, get a full tune up first and see if that clears up these problems.

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
