Question about 1994 Toyota MR2
When the ignition is turned on the sound that one hears of the fuel going to the fuel injectors from the fuel tank is non existent secondly when the car does start after 6 to 8 cranks it lacks power/accelaration and moves in a jerky manner.if i try to reset the ecu by disconnecting the EFI & ECU fuses and start the car again, the sound of the fuel going to the fuel injectors is still non existent but the car seems to regain power till the problem starts all over again after having driven about a kilometer or so. This has been a full time problem for last 3 years and everything else with the car seems fine i e the car has never broken down.
Check the fuel pump relays are operating fine this happened in my mates wrx and it was those relays would go first thing but once going relays seem to get a tad warm and then fail leave it 4 a day and it starts up again hope this helps

sounds like the throttle potentiometer. its a box above the acc pedal which sends a signal to the ecu to let it know how far the pedal is pressed. unplu the connection and spray it with electrical cleaner. may need replacing
