okay so its been atleast 2 months since i swapped a dohc zc into my rex.....still not gettin fuel.....what are all the things that could be the reason its not gettin fuel then ill list them and knock off the ones that i have already tried or checked thanks guys or if you think you know then that would be great too, i have already changed the pump and tank and filter ive gone through 3 main relays too, whats left???

 

Clogged Fuel Line
Clogged Fuel Filter

If the pump is receiving power and pressurizing the line, somewhere along the way fuel is being restricted and you need to find where that is.

 

how do you know its not getting fuel? does it try to start? take the fuel line off and see if its getting anything, if you havent already.

 

When I put a ZC in my rex about 8 years ago, all the injectors were clogged with old, gelled fuel. Swap out your injectors with some ones you know work.

You can also pull your injectors out of the manifold and leave them plugged into the rail. Try starting the car and watch to see if the injectors squirt fuel into the air.

Also, make sure there is enough fuel in your tank... especially if your car is on a hill or on jack stands only in the front.
