View Full Version : Saturn looses spark after warm-up

03-08-2009, 10:45 PM
Symptoms: looses spark as engine warms up. Thirty minutes later, car goes for 4 min and again no spark.
New IGN coils since the resistance was too high but still identical problem.

Using a Haynes manual 87010 for the 94 Saturn SL2, and reading chapter 5.4-section 6 Ignition Check

Item 6 states that the black-white wire should have 200 ohms. The paragraph continues, The resistance should be 200 ohms, check for an open or short circuit.

This is a ground wire. The impedance of the line should be zero.

Is this a misprint?
If not what am I missing

Please contact our research department at reserch@haynes.com and they will help you. They will need to know what is the Haynes manual number that you purchased. Its located on the first page towards the bottom next to the Haynes logo. It looks something like this (2d8-34444) and all of your vehicle information (year, make, model, engine etc..).
