Check to verify that tbe white wire is seeing 12v during cranking. Not just keyed 12v. Its has to see 12v while cranking to show rpm to fire the injectors or it is only firing iff the pump shot when cold. Believe me ive been down this road. That choke wire may not see 12v while you are cranking on the starter. Just use a test light while cranking
