1998 S70 non-turbo cranks but not starting  Topic is solved

Post by jeringo » Thu Jan 16, 2020 5:00 pm

From the original owner 300k miles. Have kept it going, running great till now. Lots of routine maintenance through the years, a few problems.

Symptoms began with sudden misfires. Multiple misfire codes were read.
First checked fuel pressure which was 38 approx. psi running roughly. Pulled fuel rail and checked injectors all clean.

Today used a spark plug light on # 3 and #4 and no spark showed. Used ohm meter on the coil and it indicates 1 ohm on primaries and 8k ohms on secondary which is as manual indicates ok.

What is next? Cam sensor or other place?

It finally made a weak spark but plenty of starter motor spin. Put in a new battery and cleaned terminals and started ok. Good test drive and power. Fixed
