That's it in a nutshell. My '99 blazer used to start almost instantly but now cranks maybe a second or two and this occured since replacing the fuel pump. I also replaced fuel filter. Give me your thoughts.

 

Have you verified pump pressure and operation after the install?
96+ Fuel System Diagnosis

 

No, i did not. What's the most economical way to do that?

 

Another thing that it does is when you're going down the highway, it sorta surges almost as if I'm moving the gas pedal slightly but I'm not. could this be related? Last Sunday, I sprayed some MAF cleaner according to directions. Thought that may have caused it. It's my wife's vehicle and so I ....you know what I mean!

 

A few guys on here(including myself) have that little surge on the highway. I remember a thread about it. I'll see if I can find it. Just a Blazer thing.
