okay i fixed the crank position sensor( however i resoldered the white and black wire, there is more exposed wire surrounding the white and black wire ) and changed the fuel pump, but not strainer, and my car will start up, then it will go down to about 200 rpms then shoot back up to 1k rpm and go back down to 300 rpms then stay a steady 1krpms or something until i rev the engine then it'll fall flat on its face ( go back to like 500 rpms ) then go back to regular idle. now sometimes it will start up and then die right after instead of falling on its face. could this be because of a bad fuel pump strainer? the strainer that the guy sent me did not fit ( angled the other way ) so i had to re use the old one... and so I dont know what else could cause this starting problem. if someone could help me i would be very appreciative! thanks
