2001 S60 Intermittent Start Problem

Post by MJRBCR »

My S60 started then turned off and wouldn’t start again. Turned over, wouldn’t fire.Towed to shop. The repair bill states: tested fuel and ignition system, no fuel pressure. Tested fuel pump circuits, poor pin fit at fuel pump connection. Repaired pins, vehicle starts.

Brought it home, wouldn’t start, towed to shop, it started every day for 5 days. Brought to another shop. Ignition and plugs OK. It’s starting.

How do I know it’s safe to drive my car? Should I replace the original fuel pump? Does anyone have a suggestion on what else to check? My car is in good shape with 170,000 miles.

I appreciate any suggestions you may have.

Sounds like it could be the PEM module. Its a fuel relay controller essentially. I would say that a bad fuel pump would necessitate replacement and not "repaired pins" as those do not normally work that way. Could have been a loose connection but its hard to tell without seeing it.

Keep driving it and note behaviours on startup.
