EDIT: I resolved this problem, it was just me putting the plug wires in the incorrect place


94 cx hatch
d15b8 block
obd1
d16y5 cylinder head (the ONLY difference from the y8 is the valve train and the vtec function)
d16y8 intake manifold
ebay header
chipped ecu
d16y* cam gear
d16y5 timing belt
d16y5 vtec solenoid

I have carefully followed every step that I know to take (this isn't my first head swap) I printed out pages from the honda service manual pdf (don't ask me where to get it) for the hose routing. I followed all the steps for that and checked over everything. I properly torqued the head down. Lined up the white mark on the crank pulley to the notches on the timing cover. pointed the cam gear up and made sure that it was in fact where it was supposed to be. Tightened the timing belt tensioner. Torqued the crank pulley and cam gear.

Electrical:
Using my d15b8 distributor, I bought all new plugs and wires. I gapped the plugs to make sure they were at the correct gap. because there's no air temperature sensor "bung hole" (heheheh BUNG HOLE) I moved it to the stock intake hose. VTEC wiring isn't hooked up, however I don't believe that this would have any effect on the engine not starting.

I have tried everything that I know to do. I have tried advancing the distributor, as well as retarding. I have tried my stock p05 ecu and my chipped ecu. I am running out of ideas on why this thing won't start.

Any ideas?

is it turning over?

the motor is turning over via the starter. And ever so often I'll hear a pop like it wants to get going.

this might be a dumb question but did you set it to #1 TDC or just "white mark" lined up???? sounds like its backfiring through the intake which is most likely timing. hopefully im wrong and you havent bent or broken any valves yet.

Bense

by lining up the "white mark" it sets cylinder #1 to TDC

order23

did you set the the cam on the correct timing marks??...do you have any compression??..is fuel gettin to the injectors..pressure regulator??..check those out

wheelmanbg

stupid question but are you getting good spark?

Bense

lol all the "noobs" replying. I don't have a way of testing the compression on an engine. fuel is definitely getting to the injectors. I had a leak at first but it was because i didn't have the fuel rail tightened.

Bense

come on guys! maybe you need a refreshers course!

schardbody

ok, so you think just setting the white mark on the crank is #1 TDC, you might need a refresher coarse. TDC with the belt on is when the marks line up and the cam marks line up. but without the belt already on you have to get it to #1 TDC the old fashion way. im not a noob, just new to the site.

I put the belt on, lined the white mark on the crank pulley aligned the cam gear to TDC and put the belt on the cam gear.

a side note, make sure the d1678 manifold fits correctly on the head of the y5. It may seem like the same manifold but the mounting surface may be different. It also depends what year y8 mani. A 99 y8 mani wont even fit on a 96 y8 head (HUGE vacuum, leack), and its supposedly the same motor (diff model year only)!

as for starting, im sure you've checked the fuel pump? primed it a couple of times?

it's a 99 manifold with the holes plugged. and the d16y5 and d16y8 have the same aluminum head it's the valve assembly and cam that's different. And yes, the part numbers for the heads are the same.

Fuel is getting to the injectors. So I doubt the fuel pump needs to be primed

Your ignitor may be the problem if you haven't checked that out yet.

The white mark on the crant is not cyl 1 TDC, make sure with the crank on the white mark, that the rotor on the dissy is pointing to the #1 spark plug wire. Also go buy a 30$ compession tester as a warped head, or a not well seated head gasget can be the problem, as i was training I screwed one up.
Good luck.

(also d16 z 6 the one marker line lines up with the one on the inner timing belt cover not the 2 lines to align with the head.)

Bense

I can't believe this. I woke up this morning and I was like hmm. Walked outside in my pajamas, swapped two spark plug wires on my dizzy and went to crank it up and it fired right up!



it happens to the best of us. Thanks for the help guys

suprmods

glad you solved it.

Luserkid

From reading the thread it sounded like a firing order problem, glad you got it fixed. Only reason why im posting is to correct this:

Thats false, a 99-00 y8 manifold will fit a 96 y8 with no problem. What youll want to do is seal up the injector air pockets it has or you could get a big idle problem.

suprmods

I put the 99 on the 96 motor, and there was quite a leak. If you look at the two manifolds together you will see that the mating surface is different. The 99 does have that extra air vent you are talking about, so for all technical purposes, witout filling in the air hole the 99 manifold will not work properly with a 96 head.
If you seal up the air pocket it is fine.

schardbody

oh, ok, i didnt know if you popped the belt and just turned the crank to the mark lined up and then slapped the new head and all on. i misunderstood, glad its fixed.
