New guy need some help.

I have a 98 mark that fuel pump died on. I bought the walbro 255 cobra unit (with future mods in mind) and installed it using a guide I found online. The car cranks but will not start. I replaced the plugs and fuel filter while i was doing the pump. Fuel pump comes on and fuel is getting to fuel rails. I put starting fluid in and car runs for a second then turns off. So i don't think it is cam or crank sensor because there is spark. The only thing I haven't done is the pressure regulator. I don't get a spray of gas out of the rails when i hit the button just flows out. Should i replace the regulator or is there another problem. Thanks for your help I have been trying to find this problem for a week. everything I have read by searching I have done and nothing has worked.

You should NOT be running a walbro 255 in your year. You need the Focus pump.

I did it using the tech article found here http://www.lincolnvscadillac.com/tech/lincoln-mark-viii/fuel-pump/index.htm So this is incorrect?

What part number Walbro pump did you use? If it's the GSS341 or GSS342, that's a gerotor pump, which won't live long in a PWM arrangement. I'm not aware of a Walbro 255 lph turbine pump.

You say you get fuel at the rails but have you checked the actual psi?

You did change your fuel filter (mandatory to keep your new pump warranty)?

I replaced the plugs and fuel filter while i was doing the pump.
