I have sparks on first cilinder, but no sparks at all on the other 3. Could anyone advice me on what to check/buy/replace?

Has phase sensor, rotor arm or Dizzy cap anything to do with this?

thanks

 

Get yourself a new cap and rotor arm,and crank position sensor first

if those fail then ask again

 

crank sensor is new, but it's the first time in life I get sparks only on one cilinder. I have tested all plug leads and coil lead and are fine.

will order new cap, rotor arm and phase sensor tomorow.

 

a frend of mine had the phase sensor out , when he put it back he changed the place of wires . He had the same problem .........

 

Ask Stu @ MSD , I'm sure I've seen this question before and he answered it simply.. i have a suspicion this may happen when the phase sensor is connected the wrong way round.
Are you saying then that the coil only sparks one out of four, and always at the No.1 position?

 

Yes. that's what happens. Tryed everything I think. Even two new coils

btw, can't be a wrong connection on phase sensor since it was running good for the last 2 years in the same position.

What I've done so far:

- Removed uprated chip and installed original 2wd ecu chip.
- Changed Dizzy cap and rotor with a new one
- Changed crank sensor with a new one
- Changed phase sensor with a new one
- Changed old spark plugs with new ones (old and new are 071's)
- Changed coil, tryed 2 different coils (normal one and group A)
- Tested plug leads and are ok (tested in a 3dr L1)
- Tested fuel pressure before fuel regulator and gave 11 bar

Engine almost started when I have changed dizzy cap and rotor, but a lot of fuel smell was originated probably from previous starting attempts and turned it off. Then returned to previous state and don't even try to start. Engine turns well. Compression was made by a friend and was ok, but don't know any values.

Starting to be desesperate. This problem started after a big bang bang (misfire I think it's the english word).

any more ideas? thanks everyone

 

still beating with my head on every wall

 

the fuel pressure at the rail (where the injectors are) was 11 bar? it should only be around 3.5 bar with the pressure pipe to the regulator removed.

perhaps the regulator is broken and allowing too much pressure which is leaking through the injectors and overfuelling bady.

can you remove the fuel rail off the inlet manifold complete with injectors and see what happens when the fuel pump runs?

 

WHen removed, injectors starts to spit fuel for around 4 or 5 seconds.

11bar is the pressure measured before fuel pressure regulator. after it yes it should be what you said, but didn't measured.

 

no, the pressure at the rail - after the pump but before the regulator - should be as i say. after the regulator, the pressure should be 0 as it's just a return to the tank that is vented to atmosphere.

injectors spitting fuel for 4 or 5 seconds does not sound good. it will be basically flooding the engine so will not fire. that will be happening while the fuel pump is running by the sound of it, as that runs for a short time when you put the ignition on. sounds like the fpr is your problem to me.

just by coincidence, i have a working one for sale on ebay, see my sig.

 

I will test with another FPR tomorrow and will let you know. I have bookmarked your Parts for sale

thank you

 

sounds to me like ya've put the main HT lead onto the wrong position on the cap i.e... a plug lead and the HT lead mixed up , especially if ya problems only started when ya changed the cap and leads!!

 

Impossible: I didn't change anything. Car was running and stoped (original problem: https://passionford.com/forum/viewtopic.php?t=200324)

Anyway, my crank pulley is missing 1 of the 4 teeth, I think that's the problem and starts to make sense about the misfiring just before it stoped.

I'm just curious about the spark at just cilinder 1.

 

sorry i misread ... i thought ya said problem started when ya changed rotor arm and cap , but what ya actually said was that the engine almost started when ya changed em!!

 

no problem. thanks for your reply anyway. I also had not mentioned the original topic.

 

Still not running

 

Does anyone knows if alternator is dead (and battery a little old) can be one of the causes to not having sparks on 4 cilinders?
