Re: How to test a coil and a fuel pump

Though I wouldn't discount an ignition problem, I think fuel starvation is the more likely cause and thus I'd do the fuel pump check that HH56 suggested and I'd do it sooner rather than later. If in fact that's the cause the diaphragm has likely begun to rupture which means that you could be pumping raw gasoline into the crankcase, not only unsafe, but it can result in oil dilution and engine damage.

If that is the cause, of course an immediate oil change is in order before you run the engine again.
