2002 Ford Escape Repair Question
2002 Ford Escape V6 3L - 4&6Cyl misfire. I check : fuel pressure (OK), comression (OK), coils (OK), spark plugs (new), injectors(OK) but i don't now if is sygnal from computer. Catalytyc converter on this side is melted inside. Only 304 & 306 codes in mem
Are the plugs getting spark?
Yes i have sparks.
How did you check fuel pressure and the injectors?
I rent fuel pressure test kit - with engine off and running was 65psi. I don't now if fuel pressure regulator is good - no change when I disconnect vacuume hose. When pressure was on I check each injector for (spray) by two wires + & -.They was working (no leaking).
Are the injectors being pulsed when you try and start the engine? Will it start if yo spray carb cleaner in the intake?
I have no problem to start engine but is not working on 4 & 6 cyl. - is shaking.
Disconnect the fuel injector harness and measure the resistance of #s 4 and 6. See attached for specification.
I would also check compression and make sure the injectors are being pulsed.
Resistance is OK ,I check all 6. Compression is 195-205 at all 6 cyl.
Can you move the individual injectors around? Like put #3 into #4, and #5 into #6, and vice versa. See if the problem follows the injectors. What about plug wire impedance?
If I recall this has a distributor. What does it look like? What about the cap?
