Starting problem 700 1992

Have a 92 740 just a few days. ran fine for 3 days then would not restart after last use. No spark at coil (flat model). Error codes do not show any faults (1-1-1). However battery was disconnected at least twice. Timing belt appears to be OK. Battery OK. All battery connections checked & cleaned. Fuse # 1 OK via visual & analog meter for continuity. Tank about 1/2 full. I believe Ignition Rex Regina. Have not checked RPM Sensor Yet. tried new coil & also used coil & module it attaches to, still no spark. Any & I mean any advice appreciated.

    Starting problem 700 1992

    Hi,

    Could you elaborate a little on what type of 700 we're talking about here.
    ie. engine size
    Carb or injection
    B200, B230 or a B280 engine
    If B200 or B230 (4cyl) har it got a turbo
    Auto or manual

    Without this information it's hard to astablish any kind od diagnosis

      Starting problem 700 1992

      Good Evening, Tulip0852:

      Vehicle: 92 740 B230F Non Turbo 4 Cylinder Auto, fuel injected. 197,000 miles, Last Timing Belt-150.000 miles. I just bought the car last week. Everything seemed fine. No previous starting issues up until I went out in AM & it cranked but no start. Checked #1 fuse OK, checked battery OK, fuel in tank OK, Checked coil spark NG no spark, Went to local autowrecker & picked up used coil & module (what the coil attaches to) same result NG, returned same & picked up new coil attached same & same result NG no spark. Took out rubber plug on timing belt cover & observed belt in place & apparently OK. Meanwhile disconnected battery (bad move) & checked connections there. Minor cleaning & reattached & then read online info, of course I lost any previous codes. Obtained fault code info & procedures, attempted to start NG no spark. Then I checked out RPM sensor on bell housing via test module on strut tower. Entered sequence for RPM sensor & result showed sensor NG. I don't know if this result is conclusive or another component could lead to a failure showing for the sensor. This is where the situation stands at the moment. Any enlightenment would be appreciated.
