The car is a 2000 L. The engine is a 2001 RS 2.5L
The car's 2.2L worked before the swap
The 2.5L worked before the swap
Timing is good
Fuel pressure is good
Coil pack and spark plugs are good
Compression is good
The motor cranks but won't start. We tested spark with an inline spark tester, and the problem seems to be with spark. We swapped a known working coil pack, and had the same result.
So, the question is; Why won't the ecu send the signal to fire?
