b18ft injectors.
Posted: 26 Oct 2013 09:24 pm
justa quick one for all you technical folk out there.
now that I believe I have all the wiring sorted on my b18ft swap (taking a while due to time constraints)
ive managed to get it to cough into life yesterday with a brief sneeze, by manually injecting fuel into the cylinders.
my quiery:
the plugs are dry, absolutely. so no fuel seems to be reaching the cylinders. I have narrowed this down to the injectors, which I have removed, and cranked the engine over to see if they spray. which they did not.
ive been doing a bit of research, and would like some help in narrowing down the problem to one of the following:
stuck injectors from being idle for so long? im guessing this engine and car have been laid up for a number of years.
possible low battery? I have read online, that if the battery falls below 12v upon cranking the ecu goes into a safety mode and will not activate?
bad connection/faulty ecu. although I believe this would effect other parts of the system.
possible low pressure to the system, although I would have thought something would have come out of the end of the injectors?
I intend to test the injectors tomorrow using an ohm meter, and compare readings to that in the Haynes manual. from memory I think they are around 15ohms high impedance and 2-5ohms if they are low Impedance.
I have voltage to the injectors, again I am unsure of the voltage that this should be.
any help is greatly appreciated.
thanks
