I still have problems after I swapped the motor.

Here are the problems/symptoms :

1*Car doesn't start by turning the ignition key and cranking the motor. I just keeps cranking without firing!I have spark at the plugs, I have fuelpressure, but noticed that the injectors do not spray fuel. Injectors or fuelrail are not clogged!

The car starts only (after a few tries) if we tow the car and dump the clutch in gear.

2* OK, so the car finally started, the car revs only upto about 2800rpm's. So I got another MAF and that cured the problem and the car idled even better. BUT, the engine revs very very bad, that thing would stall, miss, everything you can imagine.I unplugged the oxygen sensor, no difference!

Can someone please help me !! I'm on a small Island and we are the first ones with an SR20det ,so you get the picture what we are going thru!

Did you ever remove your CAS? Fuel lines running to the proper places?

Timing, OK. Wiring , I also think so.In the past we removed the CAS, it works just fine and we re-installed it correctly. Fuellines are also installed properly!

Yes, the motor is good. After it starts, it idles well but only if I hit the throtle problems begin.

What kind of recirculation or atmospheric blow off valve are you running? The symptoms would point to the cas being off, are you sure the injectors are not spraying? Have you looked in the cylinders to check, while not having a plug in?
