I need to know how to remove the font bumper on a 1990 honda civic hatchback.

NOT!!!

fuel filter check if good check fuel pump if good pressure check catverter for clog

2 pin blue plug behind glove box.

the horn is located in between the radiator and the bumper. Yes, you have the take the front bumper down to reach it.

please let me know if you need anything else or have questions.

Fuse #23 is a 15amp - Radio
Fuse #13 is a 7.5 amp - Heater

the best overall pressure is 32-34 cold tire inflation, better tire wear and a slight increase in MPG

You will need something to lift the engine so that you can take the pressure off of the mount. It sounds like your fuel pump may be wearing out and it is not responding like it should...The pump on the gas tank should be located on the top of the tank....Under the back seat....

I don't believe you do. You may have to take several of the clips or screws out, that also help to hold the bumper cover on , but that should be it

you got the right idea.the hatch is easy. the bumpers are a pain only because the hardware rusts. use something like PB Blaster to help loosen them up. Good luck, and don't forget the rating.
