Where is the starter relay switch on a 94 Corsica V6 yam
I'd start with a basic tuneup if it has not been done in awhile. Then I'd clean the fuel injectors.
On the Island of Corsica.
Remove and clean battery teminals. Check all cables and ground.
Push it off the wharf would be a good start.
bad switch.
Disconnect your battery for a couple minutes to let the system reset. Should do the trick.
Start with the stored computer codes. Connect a code scanner to the computer port and see what the computer says.
Pull off the starter and have it checked out. I bought a new from auto zone my 93 and it turned over and ran a couple of times and quit but it would start if i let it sit for awhile. If you have to buy one make sure they test it first don't take there word.
if it will run for awhile then die, and start back up after sitting awhile , it's probably a cloged fuel filter.
It's condensation. The pipe dries out in use but gets very hot. When the pipe cools it draws in air from outside and any water from the air collects in the pipe; even in a couple of hours on a wintery day.
Check the timing for the 90 Corsica. the most likely cause for the engine not starting is it has jumped time causing the engine to fire at the wrong time.
