91 CRX D15 WONT START, TOO MUCH FUEL??
I have a 91 Honda Crx standard Model with the D15 engine. It has been sitting for 5 years and started and or moved every few months.
Anyhow this year it wouldnt start so I went to the boneyard and got new injectors because i cracked the damn brown top one trying to get it out.
was throwing code 16 fuel injector on blink out of the CPU
put those in hooked everything back in, started, moved it in the garage.
Then I went to start it the next day cranks and cranks. sprayed carb cleaner, nothing.
Figured it was the notorious Main Relay RZ-0063 so I grabbed one of those and put it in, same crap.
then I noticed fuel was spraying on the windshield im like wtf?
swapped back to the original relay tryed again nope.
Pulled plugs and they were all wet and black, carb cleaned them, compressed air dried them, spark plug cleaner (little sandblaster) and blew the sand out of the threads. Left plugs out and propped the barrel of the throttle body open to help dry out over night.
Reinstalled plugs, gave it a shot. nope.
pulled plugs again wet again. fuel spraying heavily in throttle body. dried them off. inspected cap and rotor. cleaned slightly.
cleaned plugs and checked for spark outside of engine.
seen spark and started a small fire from cylinder fumes.
So im like ok if its starting a little fire out here why not in the damned engine?
So I put cap fulls of 5w30 in each cylinder to up compression because of the extra fuel sitting in there.
tried again. nope.
looked at the CPU several times to see if it would blink out a code and it wont.
I have Fuel, and spark. Cant even get it to stumble.
Seems to me that its getting wayy too much fuel all of a sudden.

Any Ideas?

This was a perfect running car with a engine with only 65k miles
I highly doubt the timing belt jumped 5 or more teeth moving the car 5 feet.
Timing belts dont start to stretch until 100k miles.
Im not ripping apart my engine ruining my timing and risk knocking holes in my pistons or bending valves and screwing around trying to find Top Dead Center for no good reason. I can honestly say I'm 99% sure this is not the case.
I have an idea of what needs to be done but I'm looking for someone else to suggest without being bias, or someone that has had this same problem.

If you think its getting too much fuel just find a clamp to pinch the fuel line a bit to test your theory. See if it starts with a more limited flow of fuel.
