2005 Cadillac CTS 3.6L
Car won't start. I checked spark and this is what's
doing. It sparks two three times than stop sparking
than sparks two three times than no spark is that
Is there a security light on dash on?
No lights. No codes. Cylinder compression 150psi on all 6. I changed crank shaft sensor.
The only light is on is battery and DTC light with seatbelt light all other clear out after few seconds.
Can ECU cause intermediate spark like that or is it how Cadillac fires the spark?
Have you checked the fuel pressure?No fuel to this system will shut the fire to coil all so.
No it doe,s not fire like that unless there is another issue ,such as no fuel going to system.
All 6 INJ CMD(ms) reading 9.28
It's starts at 35 than it drops down as low as 8.77
To low of fuel pressure,think your fuel pump is bad.
