Do the injec tors pulse when cranked, is the fuel pressure the proper pressure, will it start spraying carb cleaner into the intake?

i tried spraying quick start and it does nothing no atempt to start, i dont no fuel pressure, but it shoots out the end of fuel rail if i hold i valve and crank motor.. and i only know i am getting power to the injecters by checking power in the wires going to injec.... thanks

If it won't start with carb cleaner you have no or weak/no spark, if the compression and timing are ok.

Remote start operates the ign and starter, could be something there, the N'star has a chain, not normally an issue.
