have a 90 hf crx with b16a and it wont start. i changed out fuel pump, main relay, map sensor, ecu pr3, Alternator, spark plugs, and spark plug wires and dont know what to do to it any more. i did do a noid light test to it and number 3 Fuel Injector was the only one working right. the compression tester was good too.

 

Check rotor, cap, dizzy and timing. Check if u get spark/fuel.

 

Maybe there is a cel. Check that and get back to us

 

rotor, cap, dizzy are new too. did check the fuel injecters and they are 2.1ohms. it is only sparking on number 3. going to put a new fuel filter on it tomarrow and will check the timing too.

 

you have to check all the basics spark and fuel etc. then get back to us you are being to vague does it even turn over?

ohms sounds about right recheck manual.

if you are getting spark on # 3 then your car will never start you.

if you are getting a good spark on 3 only then problem is your dizzy and if you really really getting spark then your igniter in your dizzy is good a common problem.

It sounds like its your cap or rotor its delivery spark and its only getting thru # 3 or its your wires or spark plugs.

check the ohms in wires and check gap on plugs.

pull your plugs check them out even smell them for fuel.

you timming really has nothing to do with starting.

if you are using cheap parts you will be suprised they can be out of specs or no good even.

good luck. pm me if need more help or even if you need my number.

check your fuel too.

 

did it run before...did u do ur own wiring for the knock,vtec pressure,vtec solenoid,and o2......i know when i did the wiring i put the black wire from the vtec pressure which is the ground to the thermostat housing and it didnt start til i took it off...idk if thats it for u but thats what happend after i finished my swap..now it runs perfect..so check ur grounds

 

check your resistor box? do you have an alarm? any kill switch? and are you getting spark in all 4? or just #3?


===check the screw that holds the rotor inplace in the dizzy.===



and also check your dizzy and make sure you put it in the right way.
and check your fues's under the hood...

good luck.

 

the car ran be for then moved to a new place and parked it and it would not start i pulled every thing from my 91 hach. i did do the wiring for the knock,vtec pressure,vtec solenoid,and o2. i have checked both my resistor boxs are good. no alarm and no kill switchs in it. the screw that holds the rotor inplace in the dizzy is all good. the fues's under the hood are all good. well did fined out the fuse 14 keeps shorting out and some were might be my problem so what should i look for?
