1989 Toyota Camry lights

Generally the plate lights are changed from outside, but look inside trunk and see if there is access to it.

Have the fuel pressure checked with a mechanical gauge, if low, it may indicate a weak/bad pump.
Also remove fuel pressue regulator vacuum line for gas, if present, then the FPR has a ruptured diaphram and would need to be replaced. This could cause starting problems, since excessive gas would be pulled into intake and flood engine.
