Tracking a problem of stalling out on anything above 35mph.
put a fuel pressure gauge on the rail, found out that it's idling at about 20 PSI (from what I read it should be at 30 PSI) pulled vacuum line off regulator, went to 30PSI at idle (should be 40 from what I read) both those tests were Key on, engine running. did a Key on, engine off, only went to 20psi, should be 30psi.
Has new fuel pump, has new fuel filter, also replaced the regulator. No change after regulator replaced.
Decided to pull ECU to check capacitors and all look great, inside board looks brand new. Ordered a new one anyhow. Anything else you could think of? I have replaced a huge list of stuff before I found the fuel issue.
Coil Packs, Wires, Spark Plugs, Timing Belt, Crank Position Sensor, Ignition Control Module, Ignition Switch. Fuel pressure regulator, Fuel Pump, Inline fuel filter, Throttle Position sensor.
