Hi,
my car does not start, just turn and turn the engine...
Previously it gave P0350 error code (ignition coil primary/secondary circuit malfunction), but I did not observed any misfire or problem with it. Sometimes it came and for day not.
Yesterday after work it did not start...
I removed the ignition coil pack and did some measurements.
There are four socket for sparkplugs. Call them A B C D (B C in the middle, A D at the two sides)
There are four connectors at the end to the wiring harness. Call them 1 2 3 4
I can measure the resistance as follows:
A-D 15.6 kOhm
B-C 15.8 kOhm
1-2 1.2 Ohm
1-4 0.6 Ohm
2-4 0.6 Ohm
3-4 2.5 MOhm (very high and suspicious)
1-3; 2-3; A-B; A-C; D-B; D-C multimeter shows 1 - no line

Do you think this coil pack is bad?
If not what, else can be the problem? Fuel pump error?
