What was strange about this problem was when the psi tested good and the injecters had a nice cone and it ran well at hight speed it sounded more like an electrical problem rather than a fuel problem. One would think there would be greater demand for fuel at high speed rather than idle, never heard about checking fuel volume either but when I saw that young mechcanic spray that starting fluid into the tbi and it stayed running I wished I thought about that a week ago. Even the older mechanic was still not convinced. They installed the new pump while the tank was down and it was still up on the lift and it started by just turning the key.They should finish it by noon and test drive it . I trust it won't die when they put it in drive.
