Sudden Fuel Problem - New Pump, Good Relay 850 1994

I've not had prior experience with LMS, but I'm not sure the symptoms are entirely, but it's worth ruling it out.

I followed Klaus' suggestion. I'm not even sure my Oil light was ever "on". Something further to investigate. It cranks oddly. If it keep it up, I'll record it and post a video. I fear that the starter is dying...

While cranking, I am definitely hearing the pump running and after an extended crank, I can smell fuel.

I'll check continuity on the CPS when i get home. 0-Ohms is a bad unit, right?


Is a bad CPS consistent with intermittent pump operation? I need to explain why the pump failed to run and then came back for no reason.

I still don't have a good explanation for why the pump just "quit"... It didn't *seem* to run in-tank with applied external power, but I couldn't bench-test the old pump because it lost a terminal spade when I was removing.

When I replaced the pump, I recall that it took me several tries to get the new pump working - much longer than when I replaced my C70 fuel pump. I was close to exploring other factors, when the car suddenly fired up. It ran just fine for two weeks before the new one cut out on me.

The car had a complete tune-up last March, right after I bought it. New plugs, wires, rotor, filters, PCV system, knock sensor kit and vacuum elbows.


A year later and I'm now out over $300 with two tow trucks an a replacement pump... This car getting to be a bad investment...
