1990 Honda CRX Si will not go over 3000 rpm It Drive normally up to that point and then engine light comes on It seems the fuel stop at 3000rpm even if you floor the gas pedal?

Answer 1

Sounds wild, I had a crx that I put a B16A1 into and if the engine was cold and you tried to high rev it it would lock out anything above 3000 rpms until you reset the ECU. With out the engine code this question would be hard to answer, you might try reseting the ECU by pulling the 10Amp hazard fuse on the passenger strut tower and leaving it out for 20 seconds, then see if the problem persists. But without a diagnostic trouble code it could be an ignitor in the distributor, a faulty fuel pump, or main relay. Good Luck My CRX does the exact same thing, My problem was that i had rust in my gass tank that would clog the filter in the tank. and on top of that i had a bad fuel pump. i replaced the fuel pump and rinsed out the Gas tank and i was fine. But Also an Issue in the ECU will cause that problem as explained above. hope i could help. Good Luck
