i don't know; Me providing any input is like the blind leading the blind.

i'm assuming this is a chevy 350?

Did you put the plug wires in the right order?

Is the fuel pump putting out fuel and at the right pressure? Did you verify this and if so, how?

P.S. There are alot of other really good forums you could try that deal specifically with E.F.I. , but you probably already knew that.

You have two threads with the same issues, read the guidelines about double posting, it won't get you any faster responses, just have a little patience. I've merged them together here.

found that my tps sensor would not accept a calibration always at 100% throttle so i probed for power and found no volage anywhere also probed the sensor itself for resistance and found my meter registered that there was no connection and did not change as i turned the sensor...what the hell do i have a bad computer

Check your grounds for the system.

I would not depend on anything but a dedicated ground wire.
