Cam timing for ford focus 2004 duratec 1.6


Are you needing the twin independent variable cam timing info or is this a cam replacement initial cam timing setting? the variable valve timing itself is dependent upon the part design, and is usually controlled by oil flow (causing the timing to change hydraulically and seems transparent to the driver). However, when replacing the cam, the timing is more of a position issue using the marks on the engine and camshafts to make sure the shafts are in the proper position.
If this is for a replacement, use the marks on the block ensuring the current valve position is the proper in relation to piston position (otherwise your pistons will punch the valves and blow the head)

How to check fuel pressure 91 geo storm gsi


1.6L DOHC (same way as the ISUZU impulse ) same car.
4XE1 engine twin cam.
has MPI injection with fuel rail, regulator and loop
disconnecting the feed line and stuffing it with guage only does 1 of 5 tests. done on MPI. it does JUST the shut test.
the correct way it to check it at the filter or rail tests ports on most cars.
in some cases you must add it.
they sell banjo fittings with test ports at summit racing dot com.
so the first question on all MPI cars, is , where is the stock fittings.
other cars the rail has a schrader valve or a plugged hole to add one. (test port) did you look first for this?
to test the FPR, unplug the vacuum line running
and pressure will jump up 6 to 10 psi.
this simulates wide open throttle pressure, a key fact in getting full power from engine, i test cranking presssure, idle, 3000rpm
and wot pressures to be sure the PFR is working, not just the pump.



the spec at the rail is.

Late 1986 to 1993 I-TEC MPFI system (after VIN 0908197)
Regulator vacuum line connected-36 psi
Regulator vacuum line disconnected-42.5 to 45 psi

the shunt test can hit 60 pis easy. do so for only 5sec.
as this stresses the pump .

the only rail drawing , shows no fittings (cheap buggers)



not even a cheap plug...

24024302-wtht4tipiqsxmsfaksxjx4vs-4-0.jpg below is the twin cam, 1.6L
buy a TEE feeting, and put it at upper, red arrow.
use clamps rated for fuel injection, not chezzy screw band clamps as seen on carb cars. use the correct parts.
or you will get leak and it will not be pretty,
the filter as at 14 ID. this is the pressure feed side of the loop.
30 to 60psi , so all parts must be rated over 60, psi, (100psi is a nice goal)

24024302-wtht4tipiqsxmsfaksxjx4vs-4-1.jpg

now the words directly from the IMPULSE FSM.

Testing
  1. Relieve the fuel pressure.
  2. Disconnect the fuel line near the engine and install fuel pressure gauge T-connector in the line.
  3. Connect the fuel pressure gauge to the T-connector.
  4. Start the engine and check the fuel pressure, it should be:
  5. 4XC1-Turbo and DOHC I-Mark, G200Z Impulse: 35.6 psi with the vacuum hose of the pressure regulator disconnected and plugged. 28.4 psi with the vacuum hose connected and at idle.
  6. 4ZC1-Turbo, 4ZD1 Impulse and 4ZE1 engine: 42.6 psi with the vacuum hose at the pressure regulator disconnected and plugged. 35.6 psi with the vacuum hose connected at idle. Disconnect the VSV before checking pressure.
  7. V6 engine: 9.13 psi at the fuel pressure line after the fuel filter.
  8. 4XE1 SOHC and DOHC engine: Flow test, disconnect the hose from the EFI fuel feed line at the engine and place in a suitable container. Apply battery voltage to the fuel pump. Pump should supply 1/4 quart (0.24L) within 15 seconds. Pressure test, connect a pressure gauge in the fuel pressure line after the fuel filter, located at the driver's side frame rail. Disconnect the vacuum hose from the pressure regulator. Apply battery voltage to the pump. After the pump stabilizes, the pressure should be 35-38 psi (245-256 kPa) and hold steady.

Is the engine receiving fuel? Check fuel pump output and fuel line pressure.
Check HT lead and coil connections.
Check spark plug condition.
Check air filter condition.

Hi, I have a Focus 2001 which takes a long time to crank everytime I try to start it. I have changed the spark plugs but still no help. Please can you advise?


You may have a fuel injector that is leaking. This would cause a cylinder to flood. If you can shut off the engine then restart quickly with no problems then this may be your problem. You will need to hook up a fuel pressure gauge to see if fuel pressure is bleeding down when the engine is turned off. The pressure should stay stable. This is a good time to see if you have adequate fuel pressure otherwise the fuel filter, pump, or pressure regulator may be suspect.

I just changed the fuel pump on a 2001 ford focus.. the problem i have now is not enough fuel flow. the pump turns on. can start car with brake kleen.. then idles rough.. when given gas.. car suffocates.....


I may have read about a fuel pressure Regulator problem for that type of vehicle. I understand that there is a 10 year Warranty for the defective part. It would be worth calling a Dealer and asking if there is a Service Bulletin for your car. Have the Vin# available.

try your O-2 sensor,some models have a an electric plate underneath the coil pack,those have been known to go bad,be it out with a blink or fade away.hope this helps
