hey guys. i just swapped a d16y7 into my 93 civic sedan which is a obd1 and the motor is a obd2 now me and my buddy swapped all obd1 parts from my old motor to the d16y7. intake mani, distributor, alternator, and exhaust manifold. it still won't start. any ideas what the oroblem may be?

Check for spark and fuel.

i checked spark and fuel. both check out. do i have to use obd1 starter?

HondaPartsHero

If it cranks it's not the starter

HondaPartsHero

Did you mess with any timing components? Like belt? Color of spark?

If both fuel and spark are good then I'd be looking at timing.

4dr_eg

i havent touched the timing at all. timing belt was already on the motor. my boy checked the timing. it checked out. so idk what else to do.

check firing order, did you pull the motor yourself? did it run fine before?

what ecu are you using?

and are you 100% sure that all the components that you put on are functional?

what engine did you have before and what spark plug wires are you using?

HondaPartsHero

Not to be simplistic but a motor only needs a few things to run. Check them and post results:

Air - generally not an issue if the air filter is good

Spark -what color is the spark, yellow, white, blue? Firing order correct? What do the plugs look like? Wet with fuel? Dry?

Fuel - pressure? Fuel at the injectors?

Timing - check cam timing?

Compression - do a compression check

All in all make sure you have the ground at the thermostat clean and tight as that is missed very easily along with all your other engine/trans grounds.

i have done all the above. i may needa check the timing again. when i try to start it. it wants to start but just dont. sounds like something so simple. but just cant figure it out

4dr_eg

i got the motor from hmotors. so its a trusted motor. i havent done compression test. so idk what the compression is.

4dr_eg

got the motor to start guys. my distributor was on backwards and had a bad ground

why would you put a Y7 on anything, that motor sucks big time, i have one in my hatch and I can't wait to get rid of that slowass, oil burning p.o.s

kyden

how does one put the distributor on backwards? the slot is offset.

ive seen it done a million times ... they are the kids that were shuving the square through a triangle when they were younger.

motor is good for getting around, but if your looking for speed of course its not the one to get....just put a y8 intake manifold
