What will shut down the coil pulse from ecu but still have injector pulse,idle control module ??

No spark but has injection pulse cam senser replaced and crank to be safe.wiring checked from coil back to ecu good power checked to coils ok. so acquired full set ecu,key,body module,receiver no change. it must be an input missing to ecu ?

Don't dismiss the coil pack completely. The hi voltage side of the pack is what usually fails.

There is a very good chance the Crankshaft Position Sensor needs replaced. The CKP is what I replace the most for no spark on the 2.4 engine. It is behind the timing belt cover mounted above the crankshaft sprocket. Sometimes they just fail because the sensor was a bad part, other times teeth shear off of the timing belt and get in the wrong place and break the sensor.

Can ignition module cause engine to have no injector pulse even though it has spark


injector pulse from ECU

the ECU will have fault codes stored internally to find the cause

would check other sensors first
crank angle sensor or cam angle sensor could stop the pulse
immobilizer

if the engine cranks over and has spark
ignition would be the last thing i would checkout

Does an ignition control module have anything to do with fuel pump functioning?


1987 rangers use a device called a TFI module to control ign. timing , this merely triggers a std. coil to fire the center port of distributor cap , this device only controls the coil to fire but does send a pulse for timing back to ecu this sets the base pulse for fuel injection , but its also affected by manifold Air flow and exhaust O2 amounts (closed loop) , but engine should run in base mode (open loop) fuel timing (but not well) , fuel pump relay is enabled to run via ECU output , Now your year ranger had a tech bulletin out on fuel pumps , seems they had a problem getting them to work after a fuel filter was replaced , something about a false backpressure , no if you have no/low fuel pressure then id look at fuel pump power 1st then fuel pump itself assuming you've already tried a new filter of course

2011 swift 1.5 no injector pulse no spark


blown fuse. ; is first, as per always.
2nd is scan it, did you scan it yet? that is always 2nd.
all efi engines, all ECU , all cut injectors for (noid lamp test dead?)
you said pulse,does that mean fuel pulse or electronic pulse to injector coil..... ? all injectors dead. or just 1. same for spark.
toss coin land, noid dead. all noids
loss of. NOID signals.!
1; spark
2: lose of CMP or CKP signals (cam or crank senders)
3: ecu sees wide open throttle it cuts fuel 100%
4: ecu bad, is CEL lamp dead key on? scan it.

What activates the fuel injecters


The crank position sensor (and or) the cam position sensor send a message to the computer. The computer then activates the fuel injectors and coils.

Does ignition module control fuel


there is no such model on this car.
this car has EFI, in 1992 , the 8 valve has TBI injection and the 16valve G16B had MPI (4 injectors)
both engines the ECU, creates spark at all times.
the input to the ECU is CMP /CKL cam and crank sensors
then the ECU computes ADVANCE and then drives the ignitor
next to the Ign coil. the coil charges and the ECU release this
charge and BAM , mr. Tesla inductive spark. hits the DIZZY.
that is how spark works.

the ECU controls fuel not spark , or better the ECU controls
spark INDEPENDENTLY from fuel;. (with exceptions)
exceptions:
or are you asking about the fuel safety feature built in to all EFI
cars 1988 too now? that is the ECU does monitor Spark
and CMP and CKP and does in fact cut fuel, when the ECU
sees spark missing, yes. It cuts the INJECTORS !

as does , wide open throttle cranking cuts fuel. (injection)
and fuse is (fuel pump) cut after 3 second key on, unless you crank it or runs.

see block diagram here.

1992 geo storm starts for only about three seconds and cuts off


nice guess work now broke.
now what does reset timing mean.
spark? , cam?
if the spark was found way off that means the cam slipped.
and the belt slipped. timing just dont walk off for funs and giggles.
its a Loud horn in my year, hey buddy, the cam slipped.
seen chain cams do that too, due to horrid drivers.

questions, I only have questions: (then answers...)
1: compression each cylinder good, if not?, big issues.
they must be equal and over 150psi WOT (wide open throttle)
2: then a timing light to check spark timing.
guessing here is no good, and ignoring this timing way off a big error.

at this point test fuel works, even with the intake and exhaust manifolds in the truck, need vidoes?
this is called the TEST fuel step.
note the care order of my tests. not guessing not skipping ahead.

you car will never inject if the ECU thinks there is no spark
even if the spark is 100% perfect.
most 90s cars, look at the coil back pulses called TACHOMETER
if those die, INJECTION is HALTEd.
by design.

Ok your ECU has scan codes and does report bad crank and bad camp sensors. as does lost spark , clue you to this fact.

ok car runs on test fuel what next.?
well, fuel pressure checks
NOID lights on injectors.
clogged fuel filter, 60k service not done?
injector coil ohms test.
injector balance test if MPI engines.
lots more,. but at least my posts gets test fuel working.

it will run (at least) for the time that the test fuel, is added.
I can keep an engine runnig on test fuel for 5 min, and my finger hurts.

Why can't I get spart. Don't have injector pulse.


Loss of injection pulses usually means a loss of an engine timing signal or even the security pack preventing the vehicle from starting.
You need to check all the timing signals, crank angle sensors, cam angle sensors etc and ensure that any security is disabled or turned off.
Check for spark, if you have spark but not injection pulses, then its a timing signal issue. If you dont have spark or injection pulses, also check the ECU (the cars computer) although I do not know of any issues with this make and model.

The car cranks but won't start. There is no spark, no fuel, no injector pulse. I have manually made the contacts in the shut down relay still nothing. I jumped the fuel relay and the fuel pump runs and I...


If you remove the fuel line and crank the engine and get fuel then you could be assured that the crank sensor works but if there is no fuel while cranking then the crank sensor is most likely the fault. If the crank sensor is not the problem then it is most likely in the coil or distributor which the 97 is notorious for.

07f-150 no spark


Have you checked the ignition module..? If my memory serves me, you should have a module which controls the spark. This can be located anywhere so, if you have a distributor, it should be attached to that, if you have waste spark ignition, the module can be attached under the coil packs or mounted on the inner guard. Without been able to look under the hood, it is difficult to point out the exact location of the ign module..The module controls everything with regard to spark and the PCU only sends timing info to that module, the PCM does not directly control spark.. You may have a security pack issue ( if the vehicle has the security pack fitted) so check that the flashing security lamp is out when you are cranking the engine, if it is on or flashing, then the security pack has not been turned off and you will lose spark and injection pulses..
