2004 Monte Carlo cranks but no spark
For about 2 weeks, something was draining the battery, had to jump start several times.The last time we jumped it, I backed up onto road and if died and now turns over but getting no spark (checked with screw driver).. All of the fuses are good and I am getting fuel.. thanks for any help.
For lack of spark, I'd start with doing a deeper dive into the ICM as theyre not uncommon to have fail. Id check all inputs to it to see if it has everything it needs. Could lead you to a pcm issue or one of the sensors feeding the icm going bad of the icm itself checks out.
For the current draw issue, I'd solve the spark problem first, especially if they popped up the same time. May be one issue causing both problems. If not though, I'd go through current draw testing to isolate the problem circuit.
