I recently posted a message about my '94 850 having an intermittent hard start condition. The car would intermittently not start, it would crank over but not start. It might me 10 minutes or 8 hours before it would start again. Once running it was fine. Might start again for the next twenty times, might not. It now will shut the engine off while driving. I noticed last night while trouble shooting that once I did get it start, it ran fine, until the fan kicked on. The moment the fan kicked on I saw the check engine light flash on and the engine shut down. I have been unsuccessful at getting it restarted.

So far I have replaced the fuel filter, then the fuel pump, and will be replacing the fuel pump relay tonight. I would appreciate any advise on what to do next. I'd like to correct it myself or at least get it running long enough to ddrive it to a dealer for analysis.
