rb20 help!
alright guys im getting fuel and spark but it wont start. ive cleaned all the injectors and fuel rail. and no help i tryed to spray starter fluid in the intake didnt seem to help i checkd the plugs they are fine and i tryd spraying starter fluid in each cylinder that would get it to fire only once, tho. it also seems like its pushing air out of the intake? and backfiring when i spray starter fluid into the intake it actualy shot a flame out the last time i tryed starting it with fluid in the intake? is the timing way outa wack? plz help

If the motor start once wen you spray fluid means you have no fuel!you may have fuel at fuel rail but injector may not be working right.check for power and signal at the injector conector.

wile cranking the motor conect the test light to the positive terminal at batt an
check for pulsation at the conector one is constant power the other one should be signal.Ecm send signal to the injector so if u dont have signal u may have harnes or ecm problem,also check all the grounds!!GL on this

how did you end up with this problem..... as in, you got the motor, put it in the car and went to start it for the first time and it does this? OR you were driving it all over town and just out of now where, it wouldn't start?
It sounds like a timing problem, but timing doesn't typically just jump on its own...
I'd also check compression just to rule it out...
