YACT: Chevy Blazer Won't Start After Changing Fuel Filter

All right, while driving home from her office yesterday my mom's Blazer suddenly lost all acceleration. She managed to nurse it home, and I put it up on ramps to check the fuel filter on the suggestion of a mechanic friend. Well, it turns out this thing hadn't had it's fuel filter changed since it had left the factory... in 1995. Now, after changing the fuel filter, it won't start. It turns over, but it just won't start.

Car Specs: 96 Chevy Blazer, 4.3L Vortec V6, 171,000 miles.
 
Yes, there is fuel in the car.

And I was thinking about the fuel pump, but before I stopped working on it last night I had to turn the ignition on to roll the windows up, and fuel came shooting out of the open line, so I was hoping that it wasn't the fuel pump that went out.
 
I did almost the *exact* same thing with my 97' caravan. It turned out to be the fuel pump that was the problem.

Edit: The filter was also bad.
 
Well, it was the fuel pump. My uncle and myself dropped the gas tank and installed the new fuel pump tonight, and it started right up afterwards. I must say, that was one hell of a job, damn in-tank pumps suck.
 
Should have just run some warm soapy water through the fuel system to clean out the muck and gunk in the lines....
 
Filter may have been dirty, but I bet it was not the reason why the thing started limping home, and it's not the reason why it won't start now.

They aren't too bad with no gas in them.

The filter was on the right way, I made sure of that when i put it on. It's hard enough to get at it, I sure as hell didn't want to do it again.

isn't it just on the driver's side frame rail? that's where it was on my s10..
 
Well the 2 things that cause a fuel pump to wear out, beside age, is not replacing the fuel filter enough and letting the tank run less then 1/4. So keep up with the filter and try not to let the tank get less then 1/4 full.

I like my in tank pump. Open the hatchback.Fold back carpet. Remove screws and disconnect electrical and pull it out. 🙂

On my truck I removed the bed instead of dropping the tank.

Yeah, but there's a whole load of crap sitting in the way of it, including the nice skid plate I had to remove. It isn't too bad once you know how to move everything to get right at it.
