Question about 1986 Toyota MR2
I do not hear it running and the MR2 won't start...
The pump is in the fuel tank. To test short pin 1+2 on the air flow meter connector. Turn the ignition key to run position (2 click) and listen for the whir or hum of the pump.

SOURCE: ecu or fuel pump?
If the car is starting I would tend to believe there is a fuel related issue. There is an easy way to check for fuel pressure at the fuel injection service port. On some cars it may be tricky to find, so consult your Chiltons or other service manual to find it. Most autoparts stores will allow rent/barrow a fuel pressure gauge. Most fuel injected cars require a minimum of 40psi to activate the fuel injectors even if the ECU triggering them. There is also a test light that you be able to purchase at the parts store that can be connected to the fuel injector connection and it will flash to indicate that the ECU is triggering it.

try taking off the air cleaners air duct that goes to the engine, with the throttle open spary some carburator cleaner into the intake. Spaying for about 10 secs. should be enough. then start it up. if it runs you know you don't have any fuel going to the engine and a fuel pump would be a very possible cause, other causes for no fuel would be a fuse, a relay, or a computer related problem. Good Luck

Are you sure it's running when cranking? It should have come on when key turned on.
This is for camrys up to year '91. It may apply in your '95, also. Check the 7.5 amp ignition fuse and the 15 amp EFI fuse and the EFI main relay, all located in the fuse box next to your battery. There is also the circuit opening relay tied in to fuel pump operation. It is usually found under center of dash. It is usually not the problem, but it is part of the checks for fuel pump operation.
If your car has a " check connector" or "service connector" (also called a fuel pump check connector) under hood on driver's side near the firewall (a little 1 inch cube with a cap on it), then bridge terminals +B and Fp with a jumper wire. Turn key to on (don't start car). The pump should come on. Listen for fuel return noise from the fuel pressure regulator, and verify pressure in hose from the fuel filter. If nothing, check those fuses above. Here is how power runs to pump: Battery to 40 amp main fusible link-to 15 amp EFI fuse-to EFI main relay-to circuit opening relay-to fuel pump-to ground. Ignition switch and the computer (ECU) work the relays to pass power to pump. Hope this helps some, Randy. Good luck.
