The car ran fine and showed no prior signs of problems. Then the day after a very windy rain storm the car would crank but not start. All interior lights/electrics work.
No spark, then wiggled/tapped the coil packs a bit and kept cranking - engine started and was running %100 fine, then died suddenly after 10 seconds.
Fuses were ok. I tried another ICM and coils, wiggled wires and checked(visually) the ICM plug and then tried to start it again but wont start.
It must have been fluke that tapping the coils/wires made it start, wouldn't the car at least run poorly or show signs of performance loss rather than a sudden loss of ignition?
It also may have been fluke that this just happened after very windy rain, but I think this likely related. After reading around it seems the problem could likely be the crank position sensor or corroded wiring under the fuse box - especially on my car with major rust around there which would allow wind + rain to get in.
I have some ideas to look at but would appreciate any help. Actually I really need help with how to use a digital multimeter to perform some of the tests. I've never used it before and wanted to try to test the coil pack like in this troubleshooting guide
Testing coils & spark plug wires
not sure if this thing is supposed to have batteries in it or not... I see coilpack being tested outside of the car.
