ok guys i need opinions on this. im working on a friends 94 civic, who ever had the car replaced the motor and ecu with a d15b7. the car was original a z6 car ex. he said he has been driving the car for a while now with no problems, the other day he was going down the road and the car just shuts off, so i check it out and i notice the fuel pump isn't coming on and there is no spark, so i replace the main relay, still no fuel or spark, so i go ahead and replace the distributor, still nothing no spark, all the fuses are good, but after the new parts no change. the only thing left that i can think of is a bad ecu. that's my next thing unless some one guides me different.
