Hey i just put a used motor in my old 94 sunbird and its not starting and i dont know why....it has fire,compression,and gettin fuel but wont crank....it just turns and turns.....we just replaced the crank sensor wire cuz i soldered it and thought maybe it was the problem but it was not.....is there anything else i need to check or can do to see if it will run.....i even tried spraying that good **** into the intake while cranking and it didnt start.... any suggestions would be appreciated...thanks
its a 2.0l 4 cylinder.

check timing and not sure it has wires or not but make sure they are on correctly in the correct order

not the timing either. [&:]

Check your grounds. This is one of the things people forget to hook back up when they do an engine swap.

i thought i had it grounded good,i put the starter and cellinoid(sp?) in myself...i grounded two diff wires(1 wire had like 5 on it) to a bracket on top of the transmission pan,or where they were when i took it off.......if i have the ground wires backwards then it wouldnt even crank though right?....thanks guys

I'm not familiar with the Sunbird. But sometimes there is a ground strap from the engine to the chassis

Just throw some sawdust in it...OOPS..wrong thread. LOL

well theres a small like bracket off the starter that holds it to the engine,and i think thats where the grounds are supposed to go but its too hard to get them on there so i put them back on the bracket that holds the driveshaft up or something....but if i had em backwards then it wouldnt crank right? ill check the wires tomorrow but what else could it be besides the grounds and ****


edit....any replies tonight would be awesome

Did you reuse all the basic sensors like the maf/map, iat, iac...etc, or are you using used ones that came with the motor? You said you're getting fuel.....but are you getting the correct psi? If you're getting spark, air/fuel and good compression it sounds like it's sensor related....if it was me i'd get the specs or the sensors and use a mulit-meter to check them....i'd also clean the iac and the maf filements if it has those sensors.
