Re: Help with Aeromotive 1000 Pump
My guess would be you have a stuck injector . They do not like sitting around . Even if you had them checked is sounds like they were at idle for maybe years the way I read it . The pressure dropping to zero instant is a classic sign of an open injector . Most likely the reason the tuner can not get it to scale . I would pull them out and make you a homemade cleaner tester to cycle them on the bench . I made one with a syringe and carb cleaner . Check out youtube . I clean every injector on an engine that has been sitting . Saves a lot of headaches .
Be careful if you have an open injector . It could fill a cylinder enough to hydraulic it and bend a rod and break a piston .
I would be very surprised if the fuel pump had a problem . It should have an internal check in it . But things happen .
I would clean the injectors first . If the pump is holding 58psi it is doing its job . If the injector is stuck open it is pushing way to much fuel and causing the tuner fits .
