injection signal arrives positive double

Hello friends, they know I have a problem with U Daewoo Lemans is from the year 94, the preblema is that this finger on the road because the car was turned off and I did not start until today I was checking it and I made everything reviewed fuses of fuel pressure the synchronization point for the medium compression and things so until I realized that the injectors did not show the corresponding signal. Mass but all the terminals are positive "when the four terminals are connected to the injuries" ,,,, but when I disconnect everything and I try again there is if this normal one comes a positive and a dough I do not have if that is normal --- and pz when I start the injectors do not inject and that's why I think it is the cause that does not start .. I hope your help ...

Try the injectors in a test bank and do them that they are in good condition if they work correctly the problem is electric, and the command of the same highlights failing.

Your problem is a sensor that carries by the crankshaft is called revolution sensor This sensor sends signal to the ECU for the incentors begins by testing with an LED when starting it has to flash by an exit of the sensor this carries two that gives a signal for the spark and the other is for revolutions in some types they have incorporated the two systems but it is rrecked because they carry three cables instead of two.

How about my company I am Alonso de Huatabampo Sonora Mexico.



Look what you have to check is that the injectors do not communicate with each other by putting one for Uni and Czech when what happens is happening that you are going to put the pramer connector in the first and fogging and check the others, nothing happens you go with the one that signs and with which you are still with which you are damaged, what is not?


Well I leave you and tomorrow you answer to see that Royosale Sludos and luck
