Hi, My 1995 Mazda 626 DX stalls very intermittently every day --
usually when decelarating or idling. A Mazda dealership ran a scan but
no codes came up. The mechanic speculated that the distributor was the
problem but he was not sure.
I took the car to my personal mechanic and drove it around his shop
until it stalled. He checked immediately if there was no fuel or no
spark. There was spark but NO fuel. He cracked the line and it
started. He later came to the conclusion that it was the fuel pump. I
took the risk and he put in a new fuel pump for $700. The car stalled
again in the evening in the same manner several times.
I went back to my friend's shop yesterday. A mechanic drove the car
for 2 hours before it stalled. He bypassed the relay connected to the
fuel pump and it started. He reconnected the relay and it did not
start. He put in a different relay. The car stalled again later that
day.
We are all gettting a little tired (to say the least). The big
question: Has anyone out there come across or heard of that kind of
problem?
What could it be? The wiring, the computer, or could it be an erratic
distributor?
Thanks a lot in advance.
Eric
P.S. Car starts again immediately or within a few/several minutes after it stalls.

My friend's 626 (V6) had same phenomena as your description. The problem is
throttle body duty. After cleaned it up with brake cleaner, also cleaned
out carbon that diposited on the IAC, it became normal.
