Hey guys, I'll start off with the usual " I'm new here and this is my first post" . I have a 1980 spider 2000 that was pushed out of a barn a few years ago. My dad and I have been working on it back and forth while I'm back from college trying to get alive again.
-A few weeks ago, dad said he had it running, replaced fuel pump, regulator and an injector. Cleaned the gas tank and replaced lines. He told me it ran like a SOB and then just died...couldn't figure out why? Figured he try a new fuel pump, long story short, had it running again and the same thing happened it just died. I came home and started looking at wiring diagrams. I narrowed it down to 2 things. 1) air flow sensor or 2) ECU ground. I shorted the ground on the dual relay and manually moved the airflow sensor and she fired right up!! I took the airflow sensor apart and adjusted the spring in there. I have it running on its own, except for the manual ground. Basically I am wondering if the ECU is bad or if something is telling the ECU not to ground the fuel pump and injectors causing them not to turn on.

-Hopefully I'm posting this in the right place, if not I'm sure one of you kind Fiat lovers will tell me otherwise.

-Dave
