Long story short, the engine completely shut down one night while I was driving on the freeway. Parts replaced so far include: OVP relay, EZL module, fuel pump relay, plugs, wires, cap and rotor. Problem: the engine starts fine in the morning, idles and runs like a dream for about 15 minutes, then it shut down. Usually will have to wait a few hours before I could restart the engine. A MB tech told me to bridge #7 & 8 pin at the fuel pump relay to be sure the pump operates; it does and he told me to replace the relay. Well, no help. I did noticed after the engine shuts down, I do not get any spark from the coil. What condition would the computer not to send power to the coil?
Could it be the O2 sensor? I replaced it with an aftermarket unit ($55) along with a new converter as well to get it to pass the california smog last month. Can someone help me out, there isn't much money left for me to shotgun the problem. The car has 173K miles, is it worth the fix? The engine top half was rebuilt 80K miles ago, basically the entire AC system is new (except the AC Pump & Evaporator). I was getting 23 to 24 MPG before it acted up. Should I donate it?
