SR not starting. Redtop in s14. No priming injector pulse. - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I recently swapped a redtop in my s14, and im not getting a primer pulse to the injectors. If i start it with starter fluid it will start, and idle, but there is no pulse when trying to start. There is no voltage drop from the battery to the injector also. Any help? I've been dealing with this for far to long....haha. Thanks in advance :]

Update: Not running over 2500 rpm...sounds like launch control. Does the sr ecu have a "limp mode", what can cause it? It's also running extremely rich. black smoke rich. Any help...please

not running over 2500rpm... isn't that mafs related? check your wiring.

I believe you are correct. I'm going out to check my grounds in a bit.. Any help on the priming pulse yet?...anyone else have this problem?

Bump...the maf isn't grounding...the ground goes to the ecu, and i believe the ecu grounds it... jumped the ground to the strut tower and still nothing. Any help...Pppplease.

F me in the A...bump. I'm thinking its the ecu, because it's also running super rich, and still no start.
