Injector leaking syptoms?
Injector leaking syptoms? What would be the syptoms of a injector leaking? I have a recently tuned and put together combo. The car cranks fine when cold, seems like after some heat is in the car then it doesn't want to crank without holding the throttle slightly down to keep it running. I find this to be a very odd thing and was curious what ya'll had to say about it. Car runs fine otherwise. The tuner turned the iac all the way down and the tb is opened up so it would crank good for him. Well it doesn't crank good after heat is in the car. Any ideas?

I'm having a similar issue with my truck lately and considering I also have a pretty big imbalance of LTFT between banks I think there is an injector leaking. The problem is that it's intermittent and impossible to induce.
Does yours have the issue every time you try to start it warm? Mine keeps fluctuating between occurring often or rarely

Only driven the car twice since getting it back. So far consistently on the third stop when I go to crank the car it doesn't wanna crank up. If I hold my foot on the pedal it'll crank up but I have to keep my foot on the pedal or it'll die. Not very happy to see this. Gonna change the plugs to see if that helps because this is the first set of plugs that was installed when the engine was put together, so they've been through some cycles of lean/rich.

Also if it helps I can have a hp tuners file to send a tuner on here if they have a solution. I just have a hard time seeing this being a injector leaking down but maybe it is.

" Not very happy to see this after being "Tuned"
Sounds like the "tuner" hacked the tune, in order to get paid...
Suggest you find another tuner that doesn't do hack jobs...
As for the injs:
Fuel psi drop fast upon shut down?
You can run the engine, shut it down, let is sit til psi is dropped. Then, pull the plugs and see which one[s] are wet w/ fuel.
Has the engine been sitting for an extended time? IE: in a scrap yard. Could be, the injs need to be cleaned.

Verdad Gallardo Engine has not been sitting up in the jy. I bought the ls2 short block out of a gto with 53k miles. The heads, cam, intake, injs ,and everything else was bought from vendors or off the forums here. I don't know if fuel pressure drops cause I haven't checked it. Car runs flawless other than this no crank issue after its warm. We're going to change plugs first and go from there. I'm def not happy at all to see this.
