injectors arent firing,,,,, fuel pump is working and sending fuel to rail,,, but injector tips are dry ,,, any1 know what the max voltage they should be at,, mine were maxed at 1.7 volts,, is that enough? could somehwere the wiring be wrongggg???





p.s. DAN come to my house,, im freee allll day tommrow
 
ok so,, injectors have good Ohms around 11,, so im guesing ummmm, there dirty and not openinng, or somethinggg,
 
If you have measured the injectors and they are at 11 ohms that is what is supposed to be for high impedance injectors (11-13 ohms) . If the ECU dose not see engine RPM it will not pulse the injectors. The ecu reads engine rpm from the distributor on the ka. Check all fuses inside the cabin and engine bay. Make sure that your crank angle sensor harness plug (distributor harness plug) is installed tight and is clean. Make sure the harness is bolted into the ecu.

I had a problem where my fuel pressure regulator was stuck open. Which means that it would not create any rail pressure. Car would not start. for shits and giggles if you want, take a vice grip and clamp the return line shut so you are able to create rail pressure. Try to start the car. NOTE::::::!!!!! When you clamp a vice grip on a old dry rotted return fuel line it will crack and leak fuel. There are special clamps that are soft on hoses. Just keep in mind if you damage the fuel return line you must replace it before you attempt to operate the engine. NOTE\END
