I have a '90 chevy pickup. 350 engine. It was running fine then started
to back fire puke and fart when I would push on gas. When speed evened
out it was fine but soon as I would give it more gas it would start to
sputter. Did this while driving about 50 miles by the time I got home it
was really backfiring when I speeded up from stop sign. Next morning I
started it and it was running rough. I backed up and put it in drive put
on gas and it killed. Would turn over but would not fire. I thought was
not getting spark. I changed wires, regapped plugs because they are not
that old, new distributer cap,now when I turn it over it will start but
not idle up, it chugs for 10 or 15 seconds then kills. When it starts if
I push gas it dies right away. If I let it run untill it dies I can hear
a buzzing sound right after it dies. the buzzing is only a couple
seconds. Like something is running then stops. If I unhook one of the
injectors it seems to run a little longer. Kind of like it is flooding
or something. So it is not electrical now I think it has something to do
with the gas. Any ideas?

running when i changed the module. ran like a champ after.

First thing to check is fuel pump and fuel pressure.
