1994 Toyota Camry 4 cyl Front Wheel Drive Automatic

I found out lately that my check engine light comes up frequently even when the car is fully on motion and when it does, the engine will go off within a minute and it will take atleast 3 attempts to start it. I changed the fuel pump but the problem still persist. Also, the car do hesitate if accelerated. You got to help me here. Thanks

Hi there,

You need to run a scan and get any set fault codes, you can do this with out a scanner, locate the check connector and bridge out terminals TE1 & E1 this will cause the check engine light to flash a code, if there is a code present it will flash long and short flashes, long is 10 & short is 1's so if it flashes 2 long and 4 short its code 24 and so on, it will go through all codes stored and re start again, so watch carefully, get the codes and post them here.
