New Motor wont start??

[seyzar18]

i did a complete build on my 94 eagle talon 2.0T new pistons rods crank valves etc etc I finally got it all done and all the new guages and wide band installed and i went to start it up yesterday and it will fire up then it will sputter and die, Every time i turn it over it will fire up for a quick second then die.

I checked the injector pulse and it has a pulse and i pulled out the ecu and checked it over and everything looks good. I have messed with it for a couple hours and can't figure out why it wont stay running? Any one have any good ideas?

well you need spark, fuel, and compression do a compression test.

already did a compression check and it was good across the board. I also already checked out the no start guide and still didn't come up with anything that would keep it running.

Do you have good fuel pressure?

My Fp gauge is reading 42psi i put a volt meter on the injector plugs and its like when it cranks over and fires up it loses power to the injector plugs right after it fires and then that's when it dies? is that normal?

THe car has injector pulse till it fires up for a quick second then it looses injector pulse

check your firing order, when I installed my new ecu with dsmlink v3 my firing order changed??

wow so WEIRD thing, I decided to check injector pulse on all injectors and i did 1 2 and 3 and good but after each of them the car still wouldn't start. I pulled 4th cylinder and checked that and it had injector pulse also. Hooked it back up and BOOM it started right up..... I have no idea how why or what went on there but it started right up..
