In need of some serious help with my turbo wagon starting issue, first let me tell you i have replaced fuel pump and filter, fuel regulator, injectors, idle control valve, and of course the battery. I have fuel to the rail but no pressure at the rail, The car will start with starting fluid sprayed into air intake but then will shut off after 2 seconds.
And also the car has been sitting for 2 years but not sure even then what could have happened
Car of course is older and not really trying to take it to the mechanic and spend thousands to fix
Any ideas?

 

Jump or replace the relay.

 

Take a jumper wire and go from your plus on the batter to the red wire on your coil. Then try to start the car. This will back feed the system and bypass all relays, ignition switch and relief relay. This is a temporary test to see if the car will run. When you do this you should hear the fuel rail pressurize as soon as the connection is made. There are two power sources that control the pump. The relief relay and ignition switch.

I bought a car 850 wagon for $280 that had this problem. Turned out to be the relief relay, a free fix since I had the relay. Now the car is part of our family fleet.

 

it gets fuel to the pressur regulator but not in the rail going to try anouther new regulator today

 

Got a new regulator still no pressure in the fuel rail, tried to bypass all the relays etc.. still does not start. Why would i have fuel to the regulator but no pressure in the rail

 

You're right; that doesn't make any sense. Did you try (temporarily) pinching off the fuel return line (out of the regulator) to see if you then get pressure at the rail? If no, you have a pump problem. Was this a new or used fuel pump you installed? Below from volvo manual:

FUEL SYSTEM
WARNING: Always relieve fuel pressure before disconnecting any fuel
injection-related component. DO NOT allow fuel to contact
engine or electrical components.
FUEL PRESSURE
Fuel Pressure
1) Before disconnecting, cover fuel line connector using shop
towel to absorb any fuel spray. Connect Fuel Pressure Gauge (5011)
between fuel line and fuel rail. Seal free end of hose using Plug
(5266) or use Fuel Drainage Unit (981 2270, 2273 and 2282).
2) Lift cover on central electrical unit located in engine
compartment and remove fuel pump relay. See Fig. 1.
3) Connect a jumper wire between relay terminals No. 1 and 3.
See Fig. 2.
4) Turn ignition on. Fuel pump should start. Fuel filler
cover can be removed to determine whether main pump is operating. Fuel
pressure should be about 43.5 psi (3.06 kg/cm  ). If pressure is too
low, pinch return hose by hand and check whether pressure rises. DO
NOT allow pressure to exceed 86 psi (6 kg/cm  ).
5) If pressure rises rapidly, pump and lines are okay.
Replace pressure regulator and recheck line pressure. If pressure
rises slowly, fuel filter, fuel pump strainer or fuel lines are
blocked. If pressure does not rise, fuel pump is probably faulty.
6) If pressure is too high, remove jumper wire between relay
or fuse terminals. Remove return hose from pressure regulator. Blow in
pipe. Remove vacuum hose from pressure regulator. Blow in pipe. If
both hoses are open, pressure regulator is defective. Replace
regulator and recheck pressure.
