Ok I have a 91 crx hf
it has a rywire obd0-obd1 harness
rc440 injectors saturated so no resistor box just an obd 1 plug
it has twm 50mm itb's 48psi fp
86mm bore 92mm stroke b18c5 block
12.1:1 compression

I have check everything the car has spark
the car turns over cleanly
fuel pump primes.
injectors pulse with a test light and even took the rail off to see if fuel was actually there and it was also test to make sure the injecotrs actually work with a battery and they do all four of them.

You can crnk it for a while and pull any plug and none of them smell like fuel at all they are all bone dry.

Is it possible for the injectors to clog up all four of them. Thats the only thing I can think of at this point since everything else is working.

Help please
thanks

Ok just a small update the injectors do spray fuel when hook to a battery source with fuel pressure behind them

 

any codes at the ECU? - do you have the HF engine harness on it?

 

I have one code its the iat thats it thats all it says on the s300

It was a hf harness to begin with but its custom tucked converted to mostly obd1 engine connectors.

The car has started on this harness

ALso I have been reading something about an ignition module in the dizzy?

 

Ok yesterday I tried a working dizzy and still didnt do anything
I have power to the inj and did a continuity test from each injector to the ecu and everything seemed fine.

Anybody have any ideas

 

what ECU are you running?
You MIGHT need the resistor box.

 

he has saturated injectors, therefore no box. doesn't matter what ecu he has.

as to why your injectors are not firing i'm unsure. i would have said to test for continuity between the ecu and the injector ground but it appears you've already done that.

 

Im pulling the whole engine harness out to check that see if I can find anything.
Will update if any progress is made
