Hi I have a 1995 C200 Auto Sedan chs WDB 2020202F241703, I think I have a problem in the ECU. Only runs on two cylinders, I have changed the core pack on the 1 & 4 cylinders but the problem persists. The other problem is I don't know where the ECU (engine computer ?) is can anyone help ?

Miss firing can be cause by spark or injector pulse test wiring from ecu plug to injector plugs and to coil pack.because of ecu mounted underneath waterbottle, water causes rust to wiring and by time brakes off.

1995 buick 3.8l no injector pulse, has injector power,has spark,has fuel pressure


The injector pulse is fed from the ECU and the signal is fed from the crank sensor. The only things to check are the sensor, the ECU or the ground.

Hi i got a gwm 2.8 TD not starting.check all fuses.tested injector pulse with diode test light and no pulse found.tested ecu with another gwm 2.8 and is starting with my ecu.


Not sure what a diode test light is, but I would check with a DC voltmeter for a 12 volt pulse. The pulse is very short in duration, so you might not see it. Check for spark at the spark plugs. If fuel pump is bad, you won't have fuel pressure. There are numerous reasons for an engine not starting.

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.

How do i fix no pulse to injectors but got good spark all 6 cylinders?


Yup. Fuel supply problem. Could be a number of things. Check if the injectors are clicking when you crank. no click, no power to the injectors, problem with sensors data to the Ecu. If click, that part is not the problem. More likely Fuel pressure regulator is bad, not enough pressure, or fuel pump relay which controls the fuel pump. So either may be bad or connections are bad or wires cut. Fuel filter may be clogged. To test th fuel pump, you can jump from the battery positive to pump terminal for a short time to verify the pump is good. so then connections at pump, or from the fuel pump relay or it's connections to the ECU. Most disastrous may be the Ecu itself. Other sensors to the Ecu could contribute, but usually with code problems including sensors it goes into a "limp home" mode. overriding bad sensor inputs. If somehow you can get the error codes read at auto parts store, that may give you more clues than I can guess at. Good luck, hope this helps you out.

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.

Jaguar xj sport 3.2 no spark or injector pulse


If ECU has crank signal and engine turns over, ECU should give injectors a pulse and trigger the ignition. If not ECU might be bad. You should check power and grounds going to ECU. There are usually multiple power and grounds going into ECU

I have a 1988 300zx non turbo 3.0 just replaced the ecu thinking it was the problem but its not. My car will turn over and it sparks, tested the fuel pressure and it makes 42lbs so thats not the problem...


The pulse to switch the coils comes from the crankshaft sensor via the ecu. Pulse to switch injectors comes from the CAMshaft sensor via the ecu. Check injector wiring plugs and confirm there is an ignition live of 12v at one side. Other side should have an earth pulse when cranking.Once you know which is missing you can trace the fault backwards. ( if no ignition live then check wiring, relay, fuse etc) if no earth switching check camshaft sensor and wiring.
