Had a used motor with supposedly 47,000 miles on it installed in my 2008 honda civic about a month ago. Had to take car back to the mechanic last week because there was a leak in the power steering and was told they had to replace the elbow. After them doing the work, 15 minutes into driving home my engine light and other lights on the dash comes on. I pulled in vacant parking lot and turned the car off. Tried to start it back and car wouldn't start. Had to have car towed back to mechanic shop and it's still there! What could be wrong, it was running fine before I took it to mechanic besides the power steering leak?

 

there is a ground near the engine moint by the power steering pump, it's possible they left it off

and I believe there's a recall or service bulletin for the oring at the ps elbow, it's likely they replaced that
