i know what one is the FI ecu, cause i had to replace it after it got water in it, its behind the passenger kick panel. the car also ran with that computer compleatly removed cause when the FI ecu got water in it it shorted out and told the injectos full spray and flooded the motor. so in a atempt to get home i unpluged the ecu abd cranked over the car to try to unflood it, well to my surprise it started and ran for 10 sec on all the excess fuel then died. the way i got the car home (less than a mile) walked home got about 6 feet of fuel line and a helper friend and a can of starting fluid. now i know this is dangerous, but here goes. i put the fuel line on a vacuume port centraly located on the intake, routed inside car, told my buddy to spray away into the hose in small spurts. the whole time the FI ecu was never pluged in. well it ran good and made it home.

well i took down all the trip panels under the dash and found said ignition ecu. its under the drivers side above the brake pedal
its bosch purple tag
and it says: 0 227 400 109
made in germany (yea leave it to a german part to go bad, love german cars but japs got them beat for fual and spark systems)

anyway it smelled weird almost burned smell, took it apart but everything looks good, gona go look at it with good light and see if its a broken solder joint.
thanks again
