No fuel pressure on 94 gmc sonoma s10. replaced

Check in main fuse block with other relays. Should be labeled. Relay kicking out may be caused by overheating = bad fuel pump or dirty filter. Test fuel pressure too.

94 GMC Sonoma have fuel and fire but will not start replace rotor and spark plugs still will not fire and new feul filter and filter under can still no start any suggestions

Drop fuel tank, use brass drift and rubber hammer to unscrew retainer ring on top of tank. (Don't use anything that can cause a spark) Very carefully pull fuel pump and fuel level sensor out of tank.

Separate pump from unit and replace with the new pump. Wouldn't hurt to replace filter sock or filter if this model has one.

Carefully slip unit back into tank, replace seal and locking ring, ensuring it is tight.

If hoses and wires are long enough I check for proper operation before raising the tank all the way in place.

Once satisfied pump and fuel gage is working, replace tank in frame.

You cant drain it...Run it almost out of fuel then remove fuel tank turn upside.....That is the only way to drain it............................

try fuelfilter and check the fuel psi it maybe fuelpump.goodluck

You will have to look under the vehicle for the fuel filter, look below the seating area on both sides, if that doesn't work locate the fuel tank and trace the fuel lines forward until you locate the fuel filter.

under vehicle drivers side mounted on frame rail between gas tank and drivers door

if you can't find one, it might be that either it doesn't have one (as some cars) or it might be located inside of fuel pump assemply (inside fuel tank) but that's a longer story :)

When was the last time the fuel filter was chg.? If thats not an issue best to get a fuel pressure test.

I should not drop more than 5 psi overnight, if it does it lets the fuel drain back to the tank, this causes long crank times because the pump has to refill the lines and filter before injectors get fuel.
