New caps rotor and wiring and plugs ac delco.
car wash that spays the under carriage.

Suburban has new crank sensor.
Any idea?
pressure switch connector.
1997 chevy c1500. had it checked a local garage. They filled it up did not work.
Wiggled the connector at pressure switch and started up.
You can actually jump the a/c at the connector to get it going as a test
