I need serious HELP. I have a 91 Honda Crx Si that does not want to run. (Crank's like when you car is out of fuel)

-When the ignition is turned on, I can hear the fuel pump pump the fuel through the fuel lines.

-The engine cranks, but does not want to start. Yes, the fuel is full.

-I swapped in two different single head V-tech and each time it does the same thing.

-I tried several ECU's, but no luck.

-I took the fuel injectors out and turned on the engine and all four squirt out fuel.

-I changed the fuel filter out with a new one and still does the same thing.

I am to the point where I'm going to stripped the whole damn car out to see what the heck is going on.

i'm no expert but do u have spark and compression?

 

the problem is that you have a v-tech head, v-tech makes telephones.

Maybe if you bought a honda VTEC head you might have more luck.

Check for spark?
Did this just start happening all on its own, or did you muck around with something before it started to go wrong?

 

Replace your main relay..... Cheap and is easy and might fix your problem.

 

I'd get a spark tester from harbo freight or autozone, they are cheap and will tell you definitively that you have spark. Is your cam timing correct? Are your spark plug wires in the correct order? Are your spark plugs in good usable condition? You've check everything for fuel, but not for spark.

 

Wait, which VTEC motors did you swap in, what wiring changes were made (if any), what distributor and ECU are you using?

As others have said, you need spark and it isn't there. Sounds like a wiring issue to me.

 

X2 Check spark, then look at wiring. Test your main relay, don't just replace it, that's lame spending money when you don't even know if it's broke.
Check main relay like this...
