1998 Toyota Corolla Repair Question
1998Toyota Corolla WOn't start Corolla
I am very sorry it is a 98 corolla I always get it confused with my 240sx(1989).
1998 corolla the OBD-II code is P0105 Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction
what does that mean?[/quote:d194c0b906]
It means the MAP sensor is not working. Usually when a sensor is out of range, the PCM sets a default value to keep it running (not very smooth) this default value is usually rich to prevent damage with a lean condition (rich is bad also but not as bad as lean).
So it may be that the engine is flooded because the MAP is setting the fuel at maximum.
Check the plugs for gasoline, the MAP sensor connection (electrical and vaccum) and the fuel pressure with a mechanical gauge.

If the engine can start check the pressure with and w/o the fuel pressure regulator. Also inspect the vacuum hose for vacuum and if gas is present in the vacuum hose FPR defective.

it would be hard to remove the fuel pressure regulator because is with the fuel pump, and I'm getting 50lbs pressure, so is with in specs.... what I decided to do is to remove the fuel pressure resonator the one on the picture and cap the hole with a cork and tie wrap... crancked the engine and Wooam, the car started..... total cost of my troubleshooting...
