Hi fellas,
I had been driving my 75 2.0 FI on the highway for 4 hours on a hot day, with a couple of bio-breaks. After the last stop, while accelerating onto the highway, the engine shotdown. Stopped, checked usual suspects and after 10 minutes it started and I was on the road again. 15 minutes later I when through an interchange onto a different highway, and during acceleration it shut down again. Weather really hot now. This time it would not start again, cranked but was like it was out of gas. Fuel pressure was 30psi. Oil temp was 180 - 200 and the level was good. An oil cooler is mounted in frunk floor where A/C was. Could the heat from the oil cooler have caused the fuel pump to vapor lock? What other sensors or devices could cause the engine to just shut off like that? Car flat-bedded home,(AAA-yea). The next morning at home I gave it a try and it started right up and ran just fine. Thanks, Greg I added a photo of the frunk showing position of oil cooler to fuel pump. Attached thumbnail(s) |

Greg, it may well be vapor lock, but a symptomatically similar situation occurred about 40ish years ago to my 914. I was driving to school in the morning and after about 5 miles, engine died. Got out, looked around the engine compartment and didn't see anything unusual, tried again and it started back up. Just made it into the school driveway and it dies again. Turned out to be the ignition coil. My dad knew what to look at immediately after I described what had happened. Turns out some coils can fail when they get hot, but then work fine after cooling down. Just something else to consider.
Best of luck, Dan |
