The OVP, overvoltage protection relay, supplies power to the ECU and ABS computer. In the case the alternator fails or if a high voltage problem occurs, a zener diode conducts causing the fuse(s) to blow protecting the electronics. A problem may occur with solder joints inside the OVP case as well.

Resolder the fuel pump relay as well. This is a common problem on European cars.

Check the ABS sensors in the hub area. There may be iron filings that need to be removed. Those will cause a bad signal. The pulsing means it's working.

You need to get the codes from the ECU and fix any problem or problems indicated. Check the basics first, cap, rotor, wires and plugs. Make sure the coil wire is not fried where it attaches under the distributor cover.

You will have to elimiate vacuum leaks, bad sensors, broken wires or a bad O2 sensor, for instance.

Check and fix one problem at a time.

Do you have a shop manual/CD?
