Ford feista 2006 1.6 petrol new cam and crank sensor but still cut off while driving.what could be the poroblem

what does pulse mean, scope or NOid test lamp dead on injector
or the injector tips do now spray when engine is cranked
we can not see you doing the tests and matters.


symptoms. my guess African car, and no engine told, gas/petrol not told
sizes in CC or liters. 4cylinders? (roller cam sure)
2006 is GEN 3.
wiki says it is
1,297 cc and 1,597 cc Rocam (Roller Finger Camshaft)
1.3 or 1.6L which one? SOHC
Brazilian-designed Rocam engine is of single overhead-cam configuration with two valves per cylinder.

dead engine, cranks fast right but engine is dead, will not start or stay running.
won't start with quick start spray works, but will not stay running,
seems it has spark (spray works and sounds good)
starts but will not RUN, (spray lasts for 3 seconds)

so is the cam belt ignored and now slipped (if has belt, no books here)
all fuses, good
scan the PCM for DTC error test

the PCM cuts fuel (injectors) for many reasons, for sure to not catch fire.
1: all fused checked for good in all fuses boxes. as in ALL.
2:no real engine told or country told so folks can help with more exact answers
causes, injection dead ( but PCM fires them with electrical pulse)
top cause fuel pressure not to spec,
the crack a line dribble tests are no good. if dry yes but dribble tests mean zero.
the PSI (BAR)_ pressure must be at spec to the fuel rail.

that is one answser, now lets to , injector all 4 pins have no electrical pulse using noid test lamp or scope see the super fast pulse there, 5mS (0.005 seconds)
that cause is, PCM sees spark dead even if spark is good
the PCM seens throttle by wire dead if present, (no books in USA for bantam)
PCM sees CMP or CKP sensor errors, cam or crank sensors.
PCM sees IMMO failing (security key if has it)

now answer 3.
the engine compression is not 150psi and up tested. 10Bar up, not less.
on all 4 cylinder, and near even.

EGR stuck open
CAT core melted and now engine can not pump air, or run.
lots of test to do .
but I bet fuel pressure is wrong, at the rail 30psi up. for most cars
I have no PSI spec, 2bar up. fuel pressure. not zero not 1. but 2 up.

no car told at all,is it a car or RM250? cycle(motor)
no maker,model , year or engine told or VIN/
stop guessing and not go broke worse add parts that fails.
some CKP sensor most be calibrated, so throwing those is super wrong,
key on , engine light must come on, so does not.
that means fuses are blown, cab fuses or engine bay fuses;.
it cranks good ,so we know the battery is good.
if the PCm detects spark as bad it cuts fuel 100% on purpose, aLL EFI does that gas engine for no crash and burn and by law.

so the key factor here is NO SPARK, on all cylinders.???????
if this engine (none told) has rubber band cam drive, that is what is bad. as the LOVE to do at 60,000 miles.
are you learning car repair is see lots of post.
but not one single model. I see

• ford bantam 1997 6b and
• lexus 400
• NISSAN XTRAIL T31
• and motorcycle RM250. (relic) 03 and 04 wow 2 !

I guess you dont know what car you are messing with today?
you are not in USA (bantam ) clue huge.
so in USA we have SCAN TOOLS, 1996UP.
AND WE CAN CRANK ANY CAR AND SCAN IT FOR LOST SPARK REASON.
IT BURNS PETROL, NOT GAS, (USA WE CALL IT GASOLINE,I BET you call it petrol.
when did this secret car last run perfect.?
last week, month, year or last DECADE?
hummmmmmmm
or did you buy it dead DOA, FORD found on road dead.

If you replace a part and it makes it worse, put the old part back in and start the diagnostics again. It is also possible to buy new sensors that are faulty, especially the ones made in Mexico! Never buy cheap sensors, buy the OEM ones that the maker used.

A $5,000 professional scan tool computer will tell you exactly what the issue is with the vehicle by reading historical and live data.

5.4 engine ?

Jerking or cutting fuel supply? How did you determine that? This is most likely a sensor in the engine. Could be a fuel pump relay but it most likely is a crank shaft sensor.

Could be so many things need more info. When it cuts out, does it act as if it's running out of fuel-- sputtering, or just dead on/off? If the latter, I would suspect bad ignition module, coil, crank/cam sensor. If the former, could be fuel pump, relay, filter. These intermittent problems can be tricky.

it could be a sensor failing. crank or cam sensor. if it only does this wile at lights wouls say its the cam sensor as air flow wile moving is keeping it cooler.

Depends on engine kfx engine 8v single cam pulley. The cam pulley has a hole which lines up with a hole on the head and the crank has a hole behind the starter motor wich lines up with a oblong cut out on the flywheel not round holes they are balance holes, you can use a snake cam to look through hole to find that. Kfu engine 16v 2 cam pulleys , again the cam pulleys have holes to pin to the head and the crank has a line cut out that lines up with a marker below the pulley . Hope this helps

2003 nissan petrol xtrail stars some times other times just winds over
have changed crank and cam sensors reset ecu fitted new fuel pump still the same

dont think you can get diesel through the opening in the tank but ??? Could be a crank sensor or anything causing the problem doubt if its the petrol though
