TPI fuel pump quesiton.
Merry Christmas guys,
I just got my TPI running. This is the first time I've messed with an EFI setup, and had a quick question. The fuel pump runs for a couple of seconds
after the key is turned off. The control voltage to the relay cuts off with the key. Any Ideas?

The delayed fuel pump off cycling is normal. As a matter of fact every GM vehicle of the TPI, TBI, MPI years that I can think of at 3am does that.

My TPI car will do that too, nothing to worry about. I think the factory does that so there is fuel in the system for the next time the car is started.

thanks for the info. Everything else seems normal, and it it running good, (haven't driven it yet, still puting the fenders back on)
Hopefully I'll have it driveable soon.
happy New year
