so i dropped in a ka24de in my sohc body, and i am having problems getting it started. i am getting fuel, and i think im getting spark, and im running out of ideas. just wanting to know what to check to get this baby running.

You think you're getting spark? Why not pull a wire out make sure?

Also check too see if you wired the dash harness plug back right.

fuel pressure? fuel volume? = upto spec on the new engine? could be the cause of your no-start situation. who did the swap?

i did the swap, and im getting fuel, because it tries to turn over, (so im getting spark) its a s13 ka24de harness. i readjusted timing, and it tries, but i havent gotten it to fire up yet..

hey, pull the plug and make sure you are getting spark. when i did mine..timing was what kept my car from starting.

Ahhh! what make it fire, is fuel and spark!
tries to turn over
means your starter works!

check for spark and fuel

i set timing to spec, so i dont think that should be a problem. but who knows, this is my first swap,

i already guessed you were gettin fuel, but my question is "FUEL PRESSURE? FUEL VOLUME?" are they correct?

Take a fuel pressure reading and pull a plug and check for spark. As of right now you seem to be assuming that you have both, you need to test. Also did you take the distributor out? If you did, are you sure that you put it back correctly? Is the DE an s-13 or s-14 engine and what ECU are you using? You need to provide A LOT more information for us to help you!

it is a 95 OBD1 engine, with a s13 engine harness, along with a s13 tranny harness. it has a ka24de auto ecu, and the harness was already set up to use the 89-90 dash plug. it has a walboro 255, and i will test as soon as i can, which will probably be tonight, if i cant get it running. the reason i assume im getting spark and fuel is that i can hear combustion, it just wont turn over.

Make sure you're getting spark. Play with the distributor while someone is trying to turn it over and see if there's a difference. Are you 100% positive your timing is set right? I know that timing was my problem when I did the swap this last time around.

just because it turns over doesn't mean you're getting anything but power to your starter. pull a plug wire and hold it close to the engine bay while someone cranks the engine. a spark should jump from it to the car. if not pull the wire coming from the coil to the dist and do the same thing. if you're not getting spark there then you're not getting spark at all. if you are getting it from the coil but no the plug wire its your distributor. if you're getting spark then check fuel. you can usually put a finger on top of your injector and feel it pulse if its firing.

well, this is how i did timing. i removed the spark plug in cyl 1, and covered the hole with my hand. as i felt for compression, i continued cranking until the crankshaft pulley indicator was at tdc. i then removed the distributor, and alligned the pin with the mark on the dizzy. then reinstalled the distributor. i might have done it wrong, but thats what i got out of how to do it from my chiltons.

lol, go get a timing gun from autozone and read the instructions. first just pull a plug wire and check for spark like i said. your timing could be dead on but if you're ecu isn't sending the signal to fire spark plugs nothing will happen. a lot of people overlook a ground somewhere that keeps the engine from sparking.

Chiltons told you to use your hand to find tdc?
put LONG screw driver in and when it is at it's highest point and mark on crank is good there tdc...
do you hear it POPing? if so your 180 out...
btw...your using a s14 engine...did you swap to s13 mani?

intake mani?
most likely you are but yeah can't use s1 4mani on s13...at least not lower half runners can be swappped...

Stab in the dark but i'm going through the same motions. Check your ECU. Mine is bad and it wasn't sending the proper signal to the coil thus no crank. Question, whith ecu would be suitable or this situation? 28, 29, 30 or EP. All have been offered to me...

i also had the same problem with the ecu. Try running a manual ecu in there and see if it makes a difference. Dropped in an manual ecu and it fored up like a charm.

Any 91-94 ECU will work, auto or manual.

the chiltons said to use your hand to find when it is compressing, then rotate to tdc, so you dont 180 out. i have a timing light, but it wont even fire, and i didnt have anyone to help out, so i cant have someone crank it while i check with the light. my brother is home now, so i guess i can try that. and it is an obd1 s14 intake mani, which according to one guide i read can work with s13 obd1 setup, as it has the same electronics. i'll try using a timing gun, to see if that is even close.

so uh... not getting spark... coil isnt getting power... so what gives?

haha, im dumb, it was a ground i forgot to connect. got it start right up after that. (and adjust timing a little.) but i left it outside, and now it wont start... damn cold weather. its a little above 0*F outside.
