Re: nissan specialists
so it wont start because
i am not getting any fuel past the injectors
the injectors have been tested at 43 psi and the are good and they are firing
the person i picked the car up from said that the fuel pump went bad on him
so he replaced it. then he found out the relay wanst grounded so he grounded it out with a different ground wire without disconnecting the battery???
and the car hasnt started ever since
my guess ecu got fried becuase its under the hood where it shouldnt be
just now hooked the ecu directly to the injectors jumped the relay
and still nothing out of them and i know that they are good have been tested
i dont think the ecu is giving them the correct voltage
i had ordered an ecu already and it did not fix the problem i am starting to think i got sold a dud ecu so i ordered another
still at a loss cant figure this out

Re: nissan specialists
why the f is your ecu under the hood? i wish i lived near you so i could check it out. it really just sounds all fucked up too me. and when something has been incorrectly done there is no telling what the real issue(or likely many issues) is. since everything iis fucked anyways hardwire the fuel pump through a switch or something so you can have fuel pressure. then make sure your injector circuit is correct and the injectors are opening and closeing properly.

guy before me did it
re re
everything seems to be good relay was jumped
i have fuel pressure the injectors pulse
they were even taken out and tested at 43 psi and they are good to go
like i said the ecu was directly wired to the injectors and still nothing
so with that being said i guess that leaves the ecu to be at fault
its probably bad anyways due to the fact that it was under the hood and exposed to heat and rain more than likely
a new one is on order
and will be relocated to correct spot
