99.999% of injected petrol cars are computer controlled injection. diesel is a different story though. they used to be mechanical but some more newer models are moving to computer controlled

On your 92 colt 1.5 liter the fuel injectors are not pulsing?
I would suspect the ECU... engine computer!
Where is the fuel pump relay located on a 1989 Mitsubishi Colt 1600 GTi?
I have now found fuel pump relay behind ashtray in centre console just a shame it was not the problem looks like the injectors are not being told to open by the ecu
Do you need a new ecu or to reprogram your ecu to put bigger fuel injectors in a Nissan 180sx sr20det?
You will need to reprogram the ECU when you put bigger fuel injectors into your Nissan. The manufacturer recommends that you do not use any fuel injectors other than the originals.
What is the extra wire running to the injectors for and where does it plug into the computer at?
on tbi engines 2 injectors 2 wires to 1 injector same to other on seqential inj 8 injectors 2 wires each 1wire fused positive feed other goes to ecu is then switched electronically on and off by ecu
What could be wrong if you changed the fuel meter unit injectors pipes ECU and pump and still not getting fuel to the injectors?
Are you getting power to the system?
What actuators does the ECU control?
Some controlled devices by the ECU (ECM) would be, fuel injectors, idle air control (IAC) valve, fuel pump relay, linear EGR solenoid valve, electronic ignition control module, fuel tank vapor pressure sensor, a/c compressor relay, evaporative emissions (EVAP) canister purge solenoid, to name a few.
Why wont your Toyota 4 runner get power to the injectors?
All of them?Fuse or faulty PCM/ECU.
Is a ecu same as a ecm?
yes the ecm and the ecu is the same thing. ecu stands for electronic control module and ecu stands for electronic control unit. they are both the same thing just ecm in canada and ecu in america.
Where is the ecu located on your 1992 colt vista 2.4?
Try Behind Radio
Lincoln mark 8 ecu?
ecu= engine control unit
To put a turbo on do you need to change the engine harness and ecu Eng was rebuilt with turbo parts 92 eclipse?
Yes it will make your life much easier to have the turbo ecu and harness. The turbo injectors have a resistor pack that the non-turbo engines do not use. So that would have to be manually wired in to use stock turbo injectors and ecu.
Why would a 1990 Dodge Colt intermittently stall when accelerating slowly?
fuel injectors need to be cleaned and/or fuel filter needs to be replaced..it can also be for numerous reasons..like a bad sensor or an early indication of a failing ecu..but in most cases it's one of the 2 fore mentioned faults.if you do clean the injectors and replace the fuel filter and the car continues to 'stall' then IMMEDIATELY stop using it and see a mechanic because if it's a failing ecu; continuance of operating the car will blow the ecu beyond repair, ecus are expensive to replace and without it the car will be written-off. -freebsdkid
