I was wondering if any one knew if there is a sensor that controls when the injectors come on. i have fuel, a nd spark, but no start.
thought it was flooded so pulled spark plugs out and turned it over. no fuel in the motor. injectors are brand new. stuck in a rut. |
first thing is first. I would get a 12VDC test light and stab the lead of the test light into the power wire of the injectors and make sure that they are getting power. Then stab the lead into the signal wire and crank the engine over and make sure that the test light is blinking or flickering!!
If they are getting power and signal than I would check out fuel pressure and make sure you have like 40PSI... If you have Power, Signal and fuel pressure Its your new injectors.... Good luck! -Jared- |
go to your local parts store and get what is called a noid light, it is a test light kit for fuel injection.

It can be hard finding a noid light that will plug into the mazda harness... I found a set of noid lights at O'reillys auto for like $60 but out of all five, none of them would fit in my S5 harness... You can get a multimeter for like $10 plus you can use it for all kinds of things..
