1999 Suburban won't start unless I UNPLUG all smog etc. plugs

Asked by Mar 04, 2017 at 02:25 PM about the 1999 Chevrolet Suburban C1500 LT

Question type: Maintenance & Repair

1999 Suburban won't start unless I UNPLUG all smog etc. plugs but won't run good (with power) unless I plug them back in after getting it started.  

It was running great until a wire burned through and shut down the Suburban (while I was driving it).  I repaired the wire and experienced this peculiar starting problem ever since.  

Perhaps I missed another wire somewhere but I don't think so.  I have been all over this (HOURS spent) and can't figure it out.

It's not practical to unplug everything and plug it back in whenever I want to drive the vehicle.

UPDATE: I have swapped out the "brain" from a couple other Suburbans that I have, and that does not solve the problem. I have replace the fuel pressure sensor too -- with no luck.
