Question about 1999 Honda Accord
There is an ECM to control the starting and running of the engine but it seldom is the problem.
First you need to isolate if it is mechanical, electrical or fuel that is causing the problem.
Remove the distributor cap and crank the engine, if the rotor turns, we can skip mechanical.
Before checking any electricals, check if there are any blown fuses both under dash and hood.
Check for power supply to distributor Black/Yellow wire with ignition switch on. If there is, pull 1 plug wire out and insert a plug to its end and ground it on the engine, NEVER groud it to the battery terminals.
Crank the engine and if you see blue sparks it is ok, reddish or yellow sparks means the coils is bad.
If no sparks, the ICM is faulty.
Test for power supply to fuel pump at initial ignition switch turned on, (2 seconds only) and while cranking. If none, the main relay is faulty.
