rb25 only starts using ether then dies - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

My rb25 will not start. I checked spark by pulling the coils, and i have fuel in the rail. I removed the cas and turned it and i can hear all the injectors ticking. If i spray starter fluid into the throttle body itll fire up for a few seconds then die. I'm lost. Any help would be much appreciated.

Get a noid light tester. Sounds like your injectors aren't actually spraying

Could be ur not getting enough fuel psi for injectors to fire properly is ur regulator bad or do u have a aftermarket one? Whats ur fuel psi? Fuel filter or fuel pump could be other options fuel pump will make bearing shattering noise or it will sound weak when going out fuel filter could be restricting flow also . U got spark and ur injectors are firing but they can't fire unless they are loaded with psi from fuel system so its gotta be one of those 3. Hope this helps.
