No pressure in the fuel line when checked at the strader valve
1998 escort zx2 2.0 dohv. I have replaced the fuel filter, the fuel pressure sensor and blew out the line with air. I removed the fuel line from the pump and put a piece of hose on it draining into a bottle - I turn the ignition to ON and I get a 2 sec flow from the pump into the bottle then I turned the ignition to start and while Im cranking there is gas being pumped into the bottle. I remove the bottle and hook up the line. Then I repeat the test, I turn the key to ON three or four times and check the valve, no pressure, then I crank the engine for 5-6 secs and check the valve, minimal amount of gas - certainly not 50 psi. At no time does the motor start. it acts like theres not enough pressure to go it to the injectors. have also checked the injectors with noides, and verified spark ..... help!! Thanks

Instructions1 Pop the hood and locate the fuel rail on the intake manifold. Connect the fuel pressure gauge to the Schrader valve at the end. Push the manual relief valve on the gauge to relieve the fuel pressure in the system. 2 Place a drain pan underneath the center of the engine, on the driver's side by the firewall. Locate the fuel filter, which is on the firewall on the driver's side, toward the backside of the engine. 3 Disconnect the fuel lines running to and from the fuel filter using the pliers and then unbolt the filter from its mounting bracket using the 3/8-inch ratchet and socket. Remove the old fuel filter and discard it. 4 Set the replacement fuel filter in place. Make sure the arrow on the filter is pointing toward the engine and away from the gas tank. Secure it in the fuel filter bracket using the ratchet and then reinstall the fuel lines using the pliers. 5 Start the engine and make sure everything is running correctly. Thanks
Pull off one of the plug wires and put a screwdriver in it, crank the engine and see if it is getting a spark. If so, pull off one of the fuel lines feeding the engine and check fuel pressure. If you are not getting fire, possible causes are: crankshaft sensor, ignition module, other causes I could determine after these are checked. Try to check these and if you need further help, I will help you as much as I can. If you are getting spark, and fuel, the main cause would be timing. Hope this helps
There should be about 40# of pressure at the fuel rail. If you are getting pressure here, but its not enough to sustain your car's engine, then this sounds like a blocakage in the fuel lines. Have you checked your fuel filter?
Probably causes are; * Dirty/clogged air filter. * Dirty carburateur nozzles / bad adjustment of butterfly valve. * Wrong valve adjustment. * Distributor advance adjustment is not correct (if its not aoutomatic, if so maybe bad diaphram or sensor).
when you first get into the car, turn the key on all the way till all the lights come on on the dash, but not far enough to start it , wait a minute, then crank it over, if it starts right up, then it is a fuel pressure problem, possibly your fuel pump. if it still wont start right up, your fuel lines from the tank may be clogged.
