SOURCE: no pulse at injectors

The normal way that injectors are controlled is via the permanent application (ignition on obviously) to one side of the coil that operates the enclosed piston, and the precisely timed application of ground (negative) to the other side of the coil. The transistors that control this switching under the command of the engine computer are typically contained within the computer itself. Measuring the voltage at the injectors is not productive since the common multimeter is incapable of detecting the very short pulses that activate the coil. Some kind of visual means would be needed to observe this pulse such as an oscilloscope or an engine analyzer equipped with a 'scope.
It's unlikely that all of the switching transistors (or the injectors) have failed simultaneously so either the computer has a problem or there is no fuel being delivered to the fuel rail that feeds the injectors. You should find a pressure regulator that sits between the fuel line coming from the tank that controls the fuel pressure for the injectors. This device seem to be a sore point in many vehicles and can make it appear that the injectors are not working. Many fuel rails have a fitting similar to a tire valve to allow the testing of the pressure being delivered. I would recommend you check this before assuming that the injectors are at fault.

SOURCE: no power tp the fuel pump, injectors not pulsing, no fuel.

Check out your oil sending unit, fuel pump and relay, check for power (might be a fuse), the ignition control module (which if you remove it, can be tested for free at AUTO-ZONE), any related wiring, pick-up coil (inside the distributor), and possibly the ignition switch. If I can be any more help just as away.

I got a 2001 olds silhouette, 3.4, with p1374. Checked ecm and replaced cps on the side of the block. ran great for about 4 miles, then it started stumbling and then stalling.


DTC P1374
The 3X reference signal is produced by the ignition control (IC) module. The IC module calculates the 3X reference signal by dividing the crankshaft position (CKP) sensor 7X pulses by 2 when the engine is running and when the CKP synchronizing pulses are being received. The powertrain control module (PCM) uses the 3X reference signal to calculate the engine RPM and the crankshaft position at engine speeds above 1600±150 RPM. The PCM also uses these pulses to initiate injector pulses. The PCM compares the 3X reference pulses to the 24X CKP pulses and the camshaft position (CMP) sensor pulses. If the PCM receives an incorrect number of pulses on the 3X circuit, a DTC P1374 will set and the PCM will use the 24X CKP reference circuit for fuel and ignition control. The engine will continue to start and run using only the 24X CKP and the camshaft position sensor signals.

Diagnostic Aids
• DTC P1374 can be caused by secondary components leaking high voltage into the IC module.
• Inspect for the following conditions:
- Incorrect harness routing near secondary ignition components
- Ignition coil arcing to wiring harness or IC module--Inspect the ignition coils for the following conditions:
• Cracks
• Carbon tracking
• Other signs of damage
- Ignition coil arcing to wiring harness or IC module--Inspect the ignition coils for the following conditions:
- Secondary ignition wires arcing to wiring harness
I would sugest you take your vehicle to a qualified repair shop an have it diagnosed , but i can tell that's not your way , is it . We diagnose not replace part's .
Replace the IC module. Refer to Ignition Control Module Replacement .
Did you complete the replacement?
Go to Step 11

Replace the PCM. Refer to Powertrain Control Module Replacement .
Did you complete the replacement?

If it starts an runs it's not the crank sensor behind the crankshaft pulley .

Location of ignition control module 2001 cadilac deville


Ignition Coils/Modules
The electronic ignition system uses an individual ignition coil for each cylinder. There are two separate ignition module assemblies located in the camshaft cover of each cylinder bank. Each ignition module assembly contains an ignition control module and four ignition coils. Each ignition coil connects directly to a spark plug using a boot. This arrangement eliminates the need for secondary ignition wires. The ignition module assemblies receive power from a fused ignition feed. Both ignition module assemblies connect to chassis ground. A Reference Low and four ignition control (IC) circuits connect each ignition module assembly to the PCM. The PCM uses the individual IC circuits to control coil sequencing and spark timing for each ignition coil. The IC circuits transmit timing pulses from the PCM to the ignition control module to trigger the ignition coil and fire the spark plug. The PCM controls ignition system sequencing and timing events

It won't start. No current from crank sensor to ECM. Wiring diagram checks out.


Hey Bob how's it going ? What engine does it have 2.2 3.5 L ? An how did you test for current ? This is a AC voltage .
The crankshaft position (CKP) sensor is a permanent magnet generator, known as a variable reluctance sensor. The CKP sensor produces an AC voltage of different amplitude and frequency. The frequency depends on the velocity of the crankshaft. The AC voltage output depends on the crankshaft position and the battery voltage. The CKP sensor works in conjunction with a 7X reluctor wheel attached to the crankshaft. The CKP sensor produces seven pulses for each revolution of the crankshaft. The pulse from the 10-degree notch is known as the sync pulse. The sync pulse is used to synchronize the coil firing sequence with the crankshaft position. The CKP sensor is used for ignition timing, the fuel injector timing, misfire diagnostics and tachometer display. The CKP sensor is connected to the ECM by a signal circuit and a low reference circuit.
The best way to test is with a lab scope !

I have spark and injector pulsing, but injectors 1 and 6 pulse slower then rest of cylinders causing slight ruff idle. No trouble codes.


Way out of my league here iam afraid ,now if it had a distributor and a carb then i could give you a good answer but these new fangled things ,now firstly i would check the ?? hmm thinking no cannot be that signal going to the computer unless the crank was broke timing belt? hmm NO as valves would hit piston ,HMM aloud going to make the tea whilst i think about it ---apple crumble and custard ,lovely and my mind is still a blank and stopping smoking for 5 wks now doesnt help either anyway enough of my drivel but i think in a case like this try another ECU as inside this unit is a chip that controls the spacing of time between the initial pulse sense from the crank sensor and then the spacing for the other cylinders ,1&6 would pick up the pulse if iam not mistaken as the end cylinders normally go up and down together but not on all 6 cyl engines though ,depends on if its a inline or a V ,Be careful in changing the ECU from another vehicle as you may need the chip from the key and transponder reader from the donor vehicle and a seperate transponder reader box on some earlier models as this is a american vehicle of which i have no practical experiance .Now to drink my tea before the next question

I have a 1992 Mitsubishi Mighty Max v6 3.0. It runs rough at high speed (not necessarily rpm) and the check engine light was on earlier this week, but is now off. Does the computer retain check engine...


Yes, the computer does retain fault codes. They can be retrived either with a scan tool or by using an analog volt meter. (Good luck finding one of those if you don't already own one.)
Volt meter method:
Find the diagnostic connector located next to the fuse lock under the left side of the dash
Connect the positive lead of the volt meter to pin 1 on the diagnostic connector.
Connect the negative lead to pin 12. Turn the ignition switch on and disclosure of the ECM memory will begin.
The ECM will output 12 volt pulses. There are long pulses and short pulses. The long pulses count as tens and the short pulses count as ones. Example: 3 long pulses and 2 short pulses means code 32.
If there are 2 or more fault codes in memory, they will be output one at a time in order of the code number from lowest to highest.

Where is the cam sensor on a 2005 dodge neon sxt 2.0


Camshaft Position Sensor-On top of engine Operation The Engine Management System (EMS) uses the camshaft position sensor to manage sequential fuel injection and as part of misfire diagnosis. The EMS constantly monitors the number of pulses on the signal circuit. The EMS compares the number of camshaft sensor reference pulses and the number of crankshaft position sensor reference pulses received. If the EMS receives an incorrect number of pulses, Diagnostic Trouble Codes (DTCs) should be stored in the EMS. Some engine management systems will then default to multi-port or "gang-fire" injector operation. The camshaft position sensor signal is required to sequence the injector operation to the proper cylinder timing. If the camshaft position sensor or circuit is faulty, most engines will start. However, the EMS misfire diagnostic will likely be affected.
The following symptoms can be caused by an intermittent wiring connections or faulty signal to the EMS.
Related Symptoms
  • Extended crank time with a cold engine
  • Intermittent rough running
  • Unstable idle
  • Bucking
  • Hesitation
  • Stumble
  • Chuggle
  • Poor fuel economy
  • Stalling on acceleration
