This is a stock d16a6 motor ina 90CRX si. Ok, its started frida night. Changed fuel filter, got some gas on a connection to the left of the fuel filter. Didn't effect it at first, then it started running rough, wouldn't idle(it would just die if u didn't give it gas), missed. In retrospect, I think was running only on 3 cyl's. I had to limp it home that night. Pulled the codes, showed 3 &5, both MAP sensor codes. MAP sensor is getting good voltage, but i havent been able to change it yet. Then, it will only try to crank for a second or two and its only combusting on 2 cylinders(i felt the manifold after trying to crank it and determined this). Then only one. Now, no combustion in any cylinders. I replaced the coil b/c i was gettin some off resistance readings, still no help. I don't know if the map sensor will do this or not, and no one around here knows either. I've got a buddy with an extra map sensor, so I'm going to try to get it off him cheap. Until then, any one know what else it could be(or if it is the MAP sensor).?

 

bump, need help

 

do u hear clicks in the main relay? or does ur fuel pump prime?
