SOURCE: COLD START ROUGH IDLE
I hate to be the barer of bad news, but may be the head gasket.
My car started with rough idle. Then very hard to start in cold weather. Next started overheating, but no output from heater. Trickling sound from behind dash board. Overflow bottle overflowing.......
I replaced the water pump, radiator cap, thermostat, coolant, fan belts, power flushed the system. Nothing worked. Some research gave me the answer.
The head gasket leak was allowing exhaust gases to enter the cooling system, displacing the coolant. After use, as engine cools, coolant is sucked back into the system and coolant seeps into the cylinder. This gets worse over time.
First thing you'll notice is the rough idle as the spark plug burns off the coolant in the cylinder. (This is especially true at low temperatures.) If it is the head gasket, the other symptoms will follow as time goes by.

Make sure you have the plug wires on the correct plug. Check the
ignition timming to make sure it is correct. After running for a few
minutes pull the pluggs to see whitch cylinders are running rich. The
fuel pressure and volume need to be tested.

Additionally, try checking the power transistor. I will send the test. Also make sure the coil has a good ground...
Hope this helps; keep us updated.

check fuel pump, fuel pump fuse, distributor,and ignition coil please. then you will need to check crank position sensor.(to do this you need to find factory service manual)

H Mkawaauhau, If the engine is turning on the starter but refusing to start, you may have one or more of several problems. I believe you should have a diagnostic scan carried out on the vehicle. the problem would seem to be the crankshaft or camshaft pick up sensor, a fuel delivery problem or the on board alarm anti theft unit.
