Can anyone tell me how long it takes the fuel pump to come up to pressure during a fuel pump test (jumped test plug with ignition key on). I have my system all back together and wanted to know how long it takes approximately to check it out. I had it on for about 2 minutes, is that long enough???

I don't have a pressure gauge to hook up and test pressure, of course that would be the best answer, but baring that, any experience out there on this one???

 

I'd say about less than five seconds.

If you just depressurized the system and replaced a fuel injector or fuel rail or the like, then I'd put the full 37psi at about one and a half to two seconds on the OUTSIDE. Been there, done that, seen that. I acutally believe it's more like one second, as in *one thousand one*, one thousand two......etc

 

thanks, so what you are saying that a test of 2 or 5 minutes should have given me a good test of my newly installed system....

i can also assume that my lines are now fully charged and ready to go....
