First off let me tell you this problem is gettin a little old. I am at a lost right now and will share you my test results and what I have done. Maybe someone can steer me in the right direction. The main problem car was not starting, Cranking fine, no spark, can smell fuel with plugs removed.
Removed spark plugs. They were in poor shape so replaced.
Checked for spark, nothing pressent, fuel smell heavy, determined fuel delivery is working. As new plugs are coated in fuel.
measured resistance of the wires. all passeed except cylinder 1, 1.4 mega ohms. So i replaced the set
At the coil check primary windings with my meter. .5 of a ohm. each 1and4 and 2and3 coil
At coil checked secondary 2 and 3 10.5 kohms and 1 and 4 1.5 mega ohms (COIL replaced with wrecher unit)
Checked for power to the coil centre pin to either outside pin 12.3volts with key on
Car still not producing a spark. Scared coil from junk yard n/g removed from car and put in friends Elantra of the same year, car starts. Put his coil in mine still not starting. Test proves wreaker unit is okay to use. Swap units back.
I have been doing some reading, my educated guess right now are the cam or crank sensor.
Is there a way of testing the cam/crank sensor with out a data logger? for example a resistance check?
Can a faulty coil take out the cam/crank sensors?
Do you need both cam and crank sensors fault free for the car to make a spark?
I traced back the green and white wire on a diagram, these are ground wires to the ECM? The Bown is the 12v+ to the coil? Could my ECM be toast?
On a secondary question will a crank sensor or cam sensor issue produce multi cyclinder codes for missfire? p0300. p0301, p0304?
