The ECU. (COMPUTER)
The negative side of this coil is that it doesn't have a injector pulse. There also was a problem with the lack of spark.
The engine computer (pcm) controls the injector pulse. It looks at numerous sensors and switches to calculate pulse width
1990 ford ranger 2.3 no injector pulse what causes this
did u install all components like resister,igniter,etc from the 86? the ground 4 inj.goes 2 the intake.distributor from 86 also needed .4 more info email me. My take is that the MAF sensor enables the fuel pump and the igniter send a signal to prove rpm enabling injection pulse which is then controled by TPS and air flow along with rpm to adjust pulse width, giving the engine more or less fuel on demand.
200 Nissan exterra v6 have spark and injector pulse no power to fuel pump
where is the speed pulse wire in a Toyota corolla
Injector pulse is controlled by the ECU. Injectors Have a red wire that is hot. Black wire is controled by computer ground...
Pulse width is the time in milliseconds that the injector is energized, the duty cycle is the percentage of on-time to total cycle time
tools u can use are a noid light....or an injector pulser ''TOOL''
The engine computer.
faulty distributer, bad earth terminal on batterie also body controle unit ontop of park brake can stop injector pulse, early to late 90 models
A 92 Chevy Caprice that has no injector pulse mostly likely has clogged injectors or a defective fuel pump. Fuel injectors must be cleaned periodically to removed buildup for peak performance.
The engince control computer. Why ?
Engine control module
faulty crank angle sensor in most cases
92 mazda miata not pulsation in the injectors
A no good ecm
The engine control by way of the ignition module.
hi I have a 1986 chev celebrity also, fuel injector does not get signal to pulse the injector so it wont run unless fuel is being pured down the throttle body, ideas??
A fuel injector pulse is the product of an electrical charge controlled by the ecm to briefly open an injector. If the engine is throttle body injected, you would find the injectors in the throttle body.
The #1 cylinder is located closest to the front of engine, which is where the pulley that drives serpentine belt is. Ensure injector is getting pulse before replacing.
i take bp on cuff machine which gives pulse rate also.
There are several ways. Most people use what is called a noid light. To use a noid light you unplug a fuel injector and plug a noid light in to the harness. You turn the engine over. If the noid light flashes then you have injector pulse. Another way to check is to use a low wattage test light. Unplug a fuel injector, and plug one end of the test light to each wire from the harness. Crank the engine over and see if the light flashes.
