Answer 2
After thousand of dollars in diagnostic work from different garages, and none of them able to locate the problem. Here's what I found out. I replaced crank shaft sensor. I replaced the in line gas filter. I checked all the wiring and had to fix a couple with cracks. I cleaned the fuel pressure sensor and all the electrical connectors. No disgnostic code ever the entire time. No one would ever tell me it was fixed. Then every 3-6 months, it would crank fine but no start. I discovered the problem for my car. Near the fuel pressure sensor, there is a port to check the fuel pressure. I couldn't get the car going, the fuel pump kept working and wouldn't stop. The car still wouldn't start. I pressed on the fuel pressure nipple, air hissed out followed by gasoline. I took my finger off the nipple quickly. Got back in to the car and it started right up. It was vapor lock. I can't tell you how relieved I am to finally to discover the problem after four years of this. -
