The Symptom is like it has ran out of gas. I now own a fuel pressure gauge because of this. While driving I find that my fuel pressure would drop from 32 PSI down to 12 PSI. Run for another 20 seconds and then the engine would lag out. I would have to wait again before I could get it started again. I had some kind of spark control unit changed out, this was over a year ago when this first appeared. I then had the fuel pump changed out when I saw the fuel problem. Along with a new fuel filter at the same time. Now I have a new pump, but still the same problem. Just now, when the fuel pressure drops, the fuel pump gets real loud, giving me enough time to look to the gauge to see that I go from 35 psi to 10psi.
This all started in conjunction when a rear motor mount gave out. Also, at first, the car did not like to up shift, a week later I no longer had 1st gear. I checked the transmission fluid, it was within normal levels and still clean. The car has 144,000 miles on it now. I had a new tranny put in at 120,000. I haven't driven it in a year but now have need of it.
No computer codes come up and now I am suspecting a ECU issue. I have taken the car to four different mechanics and none of them can figure it out, but they love to give a list of stuff to try and change. I did have it act up once for me at the mechanics, but they couldn't get it to act up again so they couldn't diagnose it.
I know, I should drop it, and some one would call it a lemon, thing is, till this happened, the car has always been reliable.
