99 4dr, P0452
Just had the fuel pump replaced, filled up, drove for about a week, filled up again, and 2-3 short trips later, SES light came on. AutoZone came up with P0452. Quick search here comes up with "P0452 - Evaporative Emission Control System Pressure Sensor Low Input" and some recommendations from the "P0452 Explained" page to check the wiring harness and connectors.
The mechanic who did the pump is good, but slow, so if there's a possible quick-fix, I'd love to try it before having to stick the Blazer back in the shop for several days until he can get to it. Any chance this is just a variant of the "fuel cap" error? Failing that, where are the connectors referenced in the "Explained" post located?
While we're at it, anybody else have a suicidal rear window washer line? Every time I fix a fitting on mine, another one comes loose.
