Seems like electric issue. Check the following:
NOTE: Before replacing check if water has entered in the identified faulty areas, DRY them first and give them another try. If it start working, then fine otherwise replace
- Remove the main coil wire (the wire coming from Main coil to distributor) and try starting the engine. If no spark is generated from coil, it could be due to following reasons:
a. The main coil current wires have some problem, tighten the harness in place and try again
b. the 'Module' has become faulty. Check if the wiring harnesses are properly inserted into the distributor. If the problem still exist, 'Module' alongwith the pickup coil needs to be dried/replaced (Module costs around Rs.1200 kabli and pickup coil around Rs.800 New)
- If step-1 went OK, put back the main coil wire and now remove the spark plug wires individually, insert a screwdriver in it and place it close to engine's earth (DO NOT MAKE IT TOUCH ENGINE GROUND). Now crank the engine again to see any spark being generated. Using the same technique for all the four plug wires. Check the following:
a. If spark is present in atleast one wire, the other wires have been short circuited.
b. If spark is not there, following are possible reasons:
i) The main coil distributor wire is faulty. Complete plug-wire set will cost around Rs.950 (New)
ii) The 'Router' is faulty and costs around Rs.500 (New)
iii) The Distributor Cap is faulty. Distributor cap costs around Rs.650 (New)
The worst cases has been described above but the problem could even be a disconnected wire.
If the above 2 steps went well and there is no electric issue at all, the exhaust needs to be inspected if water has been filled in. In that case try pushing your car towards slope so that water can evacuate from exhaust.
