Hello all, long time lurker so I decided to post:

Here is my dilemma: 300E ran fine, warmed up. Parked in driveway, back in one hour, engine turns and cranks and starts up for 2 seconds then dies, then crank and crank. No start. Towed to shop. MAS control unit gets resoldered due to cracked joint, engine runs fine for 1/2 hour then next morning, no start. Replaced OVP, nothing....starting fluid gets car to start and idle for 2-3 seconds. Pump get 85 psi. 2 months ago new fuel filter, caty, and o2 sensor. Does anyone have any suggestions? I know im getting spark because it did run for a bit, thought the problem was solved but alas...no success. Do I now look at the FD? Give me something to go with here.

Thanks for your help!
