i just dropped a jdm b16 swap in my 91 civic si and it also converted to obd1 heres my problem some time it will start and some time it won't . i put the fuel gauge on the and just turn the key on and i get 43 psi, now when i go to start the car it will jump from 43-29 and keep on doing that. when it starts it will jump from 32-48. do u think my pump is on the way out the door


it i need a new pump should i get a stock pump or a performance one, should i get one for my 91 civic or can i use on from a 93 delsol ids it the same and better for my setup

 

Is the regulator on the fuel rail hooked up correctly? Have you tried changing the regulator? Replace the pump last.

agreed

 

can i use a regulator from my single vtec motor and how and i tell it the regulator is working by unpluging the vacuum hose from it. what i did was i took off the hosew off the bottom off the regulator and tried to start the car and alot off gas came out so it think that is good but if the single vtec on will work i'll try that first
