sr20 wont run FUEL / ecu problems? PLEASE HELP ASAP

[skaterfromvt]

Please help!

Im at a lost for words on this one

I just bought an sr20det black topit came with the ecu and wireharness but everything was smashed during shipping

so I replaced all the parts and when i got it running it only ran on 3 cyl the 4th injector was not firing...

The place where i bought the motor set from took off the ecu number making it impossible to tell what is wrong with it

They sent me a new harness except with the new harness where it plugs into the interior it has male connectors making the two connections male male...so i dont thing this wireharness they sent me is the right one...

Im trying to my the black top into a 89 s13 coupe

Here is what ive tried and I will try anything to get this car running

Have a spare fuel rail with injectors...

Took the injector clips and fuel supply and supplied the spare railDuring crank 3 of the 4 shoot fuel

Switched the pigtails and still 3 of the 4 shoot fuel except its a different injetor...its the pigtail that goes all the way to the front of the motor

When i switch to an e5 Ecu (which came with the harness for a different black top motor i get nothing at all...the fuel rail will not shoot any fuel??

with the E5 ecu NO injectors work no matter what harness

The junk ecu that came with my motor that fires 3 of the 4 with (the harness that it came with...the harness from a different motor)

..The brand new harness i could not find the fuel relay wire..which is usually the black and pink so i cant use this harness

Anyways

The car was running before i tried to switch the the E5 Ecu and E5 harness

Why wont this motor run with the E5 ecu and E5 Harness?? I have tried everything adjusting the cam angle sensor swaping injectors....checking spark with the coil pack...

if i try to run the car with the junk ecu and the E5 harness then it wont start but it ran on 3 cylinders with the harness the came with it...what could possibly do this?

Could I have got some kind of weird in between year motor? is there anyway to check??

why would they pop the ecu tag off!!???

what would u do?

Please help carisle is next weekend and i already bought my ticket
