fuel pump is working but when accelerating it doesnt pump enough fuel up to the engine then it will fall on its face if it is a electric pump you may have to drop the tank if it is inside and replace it if it is on the engine replace it thats what is exactly wrong with it

On all C/K's of this body-type 88-98, the fuel filter is located under the driver's side door inside the frame rail near the crossmember that supports the tail of the transmission. Replace it with AC Delco part GF-626, FRAM part G3727, or other comparable brand corresponding metal bodied filter. You should use a flare-nut wrench for the line fitting and one for the filter fitting. I'm not sure of the size needed for the filter, but the line should be 5/8". For SFI engines ('96 and later) you need to bleed off the pressure in the line. Locate the pressure test port on the fuel rail under the hood, remove the cap, press valve to relieve line pressure and recap valve. If ground clearance is not high enough to get under vehicle and work, raise it with jack and rest frame on jackstands. * Caution: Fuel in lines and filter will run out once fittings are undone. Use fuel safe container to catch fuel spill. Take wrenches and hold filter from rotating, while loosening line fittings. Remove Filter from bracket by sliding and manipulating fuel lines for clearance, and slide filter out of bracket. Reassembly is reverse of disassembly. Tighten fittings snugly. Reconnect battery, turn ignition on (do not start). Pump will make brief whirring sound - less than 5 seconds. Check for leaks. No leaks - good. Now you can drive again.

Testimonial: "Thanks For the tips should i use Plumbers tape on both ends of fuel filter before tightening?"
When the light comes on without flashing, it just means an emissions problem, when it starts to flash it has become more serious. I suspect that there was an error putting the plugs and or wires. That computer can determine if there is a misfire and it will put out a P040X, code where X represents which cylinder is the problem. This will help you not have to take each one apart. If there are more than one, check each number.
Ex. P0401 means there is misfire on cylinder number 1
P0400 is a random misfire detected.
If you take it to an Advance or Autozone they will usually scan if for free.
By the way, if you used cheap plugs instead of platinum plugs that could do it too.
Hope this helps.

you might want a good transmission shop to do this one,it is an electric solenoid located on the valve body under the transmission pan,this is a good time to have a new filter put in too.
