my 89 crx swap with b18 is not starting.....it crank but not start.?
 

When I spray some starting fluid in the throttle it start and stay for about 5 second than die. what can be the problem? I am out of idea. By the way where is the fuel pump relay located at on honda crx?

Seems like everyone's got the right answer! Check the easy stuff first and then work towards the harder ones... I'd start with the idle screw and relay... working towards fuel filter, then fuel pump. Probably need a new one... i'm feeling you got bad fuel pressure.
