thanks for the responce to my lincoln problem

here is a little more specific details on this car
1. EEC-III
2. CFI
3. higher milage
4. TPS sensor starts at 5v and goes to 8.25v, we substituted a new TPS 
without attaching it to motor just so it would send the correct signal to 
the computer for base idle, 2v or thereabouts, same problem
5.my fuel presure KOEO is about 36psi and about the same when i can get the 
car to run
the car will start and run when it has sat and cooled down but if you shut 
it off after running awhile it will not start again until you let it cool 
down again
6. i checked KOEO BMAP readings and it was within range

i have not quite figured out how to read codes on this system yet but i am 
working on that next
tommorow i will  check some of the more basic engine systems as you guys 
suggested

thanks, hope you have some more ideas

Andrew
