I have a 90 CRX DX that I converted to MPFI via a JDM SOHC ZC. I did all the necessary re-wiring, ecu swap, dizzy, etc...and it was running fine. Well I left it in the U.S. while I was overseas with the Army. My dad kept it running until the battery went dead a few months ago. I replaced the battery the other day and it ran fine for about 4hrs. The next day I came out and it wouldn't start. I drained the tank (really old fuel), cleaned the injectors, and plugs replaced injector o-rings, fuel filter and air filter. I verified that the injectors were working (covered me in gas) and that I had spark (pretty blue flame from spilled gas). Now if I hold the ignition for a few seconds it will eventually start but run super rough, then stall. If I unplug the vacuum line from the dashpot it will run, but idle super high. Oh, I also replaced the O2 sensor because I was getting that code and that went away. The timing is +/- 1 degree so it shouldn't run so rough. Any suggestions? Like I said it ran great the day before!!!
HELP ME PLEASE !!!
