What is the correct fuel pressure for a 98 Lincoln

sadly we can not not into parts swapping

Did you check the electrical circuit ? Fuel pump relay , inertia fuel cut off switch ? Find a wiring diagram at http://bbbind.com/free_tsb.html Ford Electronic Returnless Fuel System Diagnosis Part 1 fuel pump driver module , controlled by the engine computer .

Read the tire sidewall & add air to within 4 lbs of
max pressure on side wall

My guess would be about 40 lbs

It is impossible to answer your question without knowing the YEAR and ENGINE of your Lincoln Continental.
Also, whatever possessed you to REMOVE your fuel tank?? How are you getting fuel to the engine?

I'm not aware of a fuel pressure sensor, you have a fuel pump relay and inertia switch that powers the pump, and a fuel pressure regulator on the fuel rail. If there is a fuel pressure sensor, I would think it would be on the fuel rail with the injectors.
Have you replaced the fuel filter and checked the fuel pressure with a gauge ?

the immoblizer is on lock and unlock the drivers door using the key to reset it,noe try to start..good luck

your pump should supply 6- 10 lbs of pressure,, If you have to turn the key again to build it up more, you have a bad pump, its not holding a constant pressure, which will make for hard starts , and even if bad enough stalling of the vehicle

fuel pressure should be about 35.lbs.

Im not quitre sure but did you bleed the system...on the fuel rail on the intake there is a zert fitting like a tire valve try bleeding the system could be trapped air

check the power distribution center ,,, also check the key to make sure the chip is still in it
