My 88 toyota camry wont accelerate when i step on the gas pedal

Based on the limited information, I would start checking heat shields on the exhaust for anything loose.

Check the Fluid Level of your Transmission, You could also have worn clutches but I would start with the Transmission Fluid Level. Be VERY CAUTIOUS to use the Correct Transmission Fluid or you will damage your transmission and cause you quite the headache.

Plugs ,wires,coils.

change fuel filter

Make sure the cable from the pedal to the throttle is good and hook up
to the throttle. When you press the pedal it should pull the throttle to open.

Being that you have a 1998 Toyota Camry, these cars are fuel injected and shouldnt need the gas pedal depressed to feed fuel to your engine. It's possible you may have a dirty fuel pump or dirty injectors. Here are some possible steps (cheapest in $) so follow these in order to spend less money.
- Run some Lucas Fuel System Cleaner (green cap bottle), do two treatments of that in your gas tank and see if that makes a difference. Dirty lines and clogged injectors are caused by cheap gas and or constantly running on Empty thus allowing fuel pump to pick up sediment from bottom of gas tank.
- Sputtering could also be worn spark plugs (too big of a gap) and or faulty spark plug wires or both.
-Timing chain issues usually occur if you hear a constant vibration near the top of the engine.
-Transmission issues would be having trouble putting the car in certain gears, or the transmission stick does not sit in gear properly (slippage).

Just some suggestions that may help with your problem.

check all fuses to computers.. if they a fine you probably blew the computer out...

sound like a bad fuel pump.

The ignition is too low (i,e, rpm). Increase it.
