Long cranking after injector install

[eclipto98]

So i installed some 760 precision turbo injectors and put in the values for link but now it takes longer cranking to start is that normal? i have to hold the key on until it bogs up and starts

Was only the first start after install hard? Or multiple try's afterwards?

multiple, could it be a loss of fuel pressure when its sitting?

 

[SmalltownDSMer]

Do you have a aftermarket fuel pressure gauge to tell you what pressure you are at? Did you reinstall everything correctly?

Did u just scale the injectors in link. Or did u set the dead times as well?

 

[eclipto98]

Yea I put them n link and set dead time to 300

 

[eclipto98]

No to the after market fuel guage but yes to the reinstallation. It runs fine under load it's just the initial start up and idle . It idled like it's missing I have bigger cams but it wasn't like the with my stock injectors

Possible. Check if have a leaky FPR or fuel pump check valve.

Where is the fuel pump check valve . I thinks it's because the injectors were sitting for a while my idle is smoothing out and it's starting Normal
