i am having a problem with my fuel delivery...i think. it is a 86 rx7 and fuel is getting to the injectors, but not out of them. what needs to be changed? any sudgestions are helpfull.

rx7b13

clean your injectors

dero

its not the injectors...the injectors are not getting a pulse. but i dont know what makes it do that. thats what i need to know.

rx7b13

ok make sure your injectors are plugged in, and if that isnt problem then you got a short

dero

i haev an idea what it might be,but i am not sure. it might be the fuel distribution module. if that is not getting any power than would that be the problem?

rx7b13

very possible, wait you meen the pump? cause the only thinig that i can think of that has anything to do with fuel ditritbution would be the fuel rail and fuel pressure and the fuel pump is what gives your fuel lines pressure

The ECU pulses a GROUND to the injectors.

Make sure the EGI INJ and EGI COMP fuses in the engine bay are good.

Next, make sure you have spark. This is easy. Just crank the starter over and watch the tach. If the tach bumps a touch as you crank the starter, you most likely have spark.

The CAS signal to the ECU determines the timing of the spark and the timing of the fuel injectors. So? Do you have spark?

umm im prety sure i have a spark. the engine turns over it just doesnt catch because there is no fuel.

dero

is this going to be hella expencive to fix?

dero

ok well there is no spark. and i am prety sure if there is no spark then the ecu will not send a signal because they are all connected. i just dont know what is causing it to not spark. at one point the 2plugs on the frist rotor did have spark, but now nothing on both.
