I have a 95 coupe dx,I am out of ideas now. It has a b18a1 engine with b18b1 intake mani,ecu,etc. Just recently it started running on 3 cylinders. Then the further i drove to my shop i lost more and more power until it died. I checked timing and it was dead on,compression is 150 across the board. Whoch isnt great but still not enough to cause this. I am getting no engine codes,I tried cleaning up the thermostat ground and even routed it to the battery as well. I have switched the main relay,tried a known good fuel pump,lines are all new as well plus brand new fuel filter. had 50 PSI to the filter.ETC. the only thing that made it run right again was changing out the injectors out.And i was estatic after hours of testing and checking. And then i drove maybe 15 minutes and it started to do the exact same thing again... I was stranded so to limp it home i figured I would try clamping the return line off and build some pressure in the rail.It worked great except it had less power at higher rpms.I wasnt about to go out and try to race with it anyways.Just wanted to test wether under a larger demand if it would put out.And it never. So after all of this i get it home here.I have tried everything. New dizzy,another fuel pump just in case. I have been testing the power and ground to the main relay and out. I am lost.Please help me!!!
