i just installed my dsm blue top 450cc's. there is not leaks anywhere that i can see, but with the engine off but the key on my fuel pressure dwindles down to like 20 psi slowly. could this be an injector stuck open?? note: i have not installed the injector wires/clips. i just wanted to see if it would leak....no leaks but a drop in pressure

have u tried starting it? WHen u turn the car to "ON" the fuel pump "primes" the fuel system with pressure. If you leave it sit there it will slow loose pressure. If it didnt loose pressure there would be no reason to let it prime in the first place.

it held when the car was running....now it doesn't seem stuck anymore....injectors have been sitting for a couple years

so all is ok?

My D series CRX fuel pressure sits at 20PSI when ignition is off. Then it shoots right upto 60PSI (too high?!?!) when turned on after a while it floods and refuses to spark.
can you soak injectors in carb cleaner or something to clean them out?

Dr.Boost

IMO opinion 60psi is too high.

thought so, thick black smoke and a stench of petrol was in the air. turned it down to 40 now

40 = stock fuel psi.
