replaced engine - cranks but no start

replaced my 01 engine with a 99 engine - the engine i put in was running smooth the day i removed it from the other vehicle and my car was working perfectly fine until it ate a valve

i started it perhaps 3 times for just a moment as it was running rough

i do have the vac lines half disconnected and likely not connected right but previous to engine replacement the car had run regardless of what vac hoses id taken off for other reasons


(speaking of vac lines is there a legible diagram or photos somewhere as to how exactly they should be?)

i do smell gas when cranking it.

tried 2 different DI's

all wires are connected except the oil pressure sensor? back rear single wire connector behind starter... as i was fiddling underneath trying to connect it the flippin wire at the connector from the harness broke off so i said fuck it. theres no signs of sludge whatsoever


any ideas?

*also my engine has brown injectors and the one i just put in has red injectors if that truly will make it not start but as i said i smell gas just doesnt seem like its trying to fire

my fuel pump and filter both have under 20k on them i believe

If you hear the pump prime when you turn the key to 'ON' then the pump is fine, and the ECU is not running the pump during cranking. This can be from a bad CPS.

Make sure you didn't mix up the CPS and O2 sensor connectors, they are color coded. The CPS connectors are blue.

im getting fuel now and plenty of it.. i poured some gas directly into the throttle body too and not even an attempt to start it so im having some sort of ignition issue.. is there a ground wire in particular that would prevent a spark? i know i have all grounds connected but the engine i put in was a corroded POS so maybe the important one isnt making good enough contact? if a ground is actually what it could be.....

in hindsight replacing the engine on this car was pretty easy... considering I really didn't have any of the real proper tools for the job there were a few swearing fits but all in all definitely feels like something that can easily be done in less than half a day with the right equipment

going tomorrow to see about a vac or pump to get my clutch fluid flowin then my first engine replacement will be complete <3 this car
