My student-teaching daughter has a nice black 2005 Saturn
Vue AWD with a little problem. Once in awhile, more often in afternoon sun, it cranks full bore but never catches until it sits for 30-90 minutes, or you have it towed.
There is no fuel smell, and no plug wires so I can't do a spark check like I did in the '80s. It will start happily for weeks at the repair shop without malfunctioning, but one time, a guy in a parking lot says to pop the hood, and raps the big fuse & relay box under the hood with pliers. Vroom!
I pulled the top from the box and swapped the fuel relay with another identical one, and the fuel fuse is fine. It failed as soon as I put the top back on the box, but the rubber mallet got it going. The box does not seem to split or R&R without a lot of work. Since I didn't smell fuel I didn't swap the ignition relay.
She just pops the hood and taps the E box with the mallet now and then. It starts every time, and she says she hears a ding near the grill.
A reliable, though not resalable solution. Any ideas?
