I need help troubleshooting my 1995 E320 sedan. Ive had it 4 months its got 140k miles. It has a good crank but wont turn over. It has done this before a couple of times and I would turn my key to the off position wait a few seconds and the second time it would turn over no problem. But this time not so much. It will only crank.My check engine light is not on. The only light I have on is ABS. What should my fuel pressure be? And any other troubleshooting suggestions would be greatly appreciated
