Here's the deal, vehicle is a 95 ej1, which the stock d16z6 threw a rod.(250k miles) So, I purchase a "jdm" d15b vtec from gold autos, everything worked great on the d16z6 so whatever worked was transfered to the d15b.(dizzy/plugs/ injectors/fuel rail/sensors..etc)
When I replaced the timing belt (oem parts vx belt/z6 tension) I marked serveral spots on the cam/crank gear with the old belt before removal and matched/marked it tooth for tooth onto the new belt.(fool proof I though) and spun the motor by hand about..4 revs? Everyting lined up again.
To the point. D15b is in but won't fire..The closes it came to starting was two clyinders fired after about..3 cranks?
- I grounded a spare spark plugs for each cylinder(white/blue spark)..check
- checked for tdc/dizzy rotor relation...check
- firing order... check
- removed S.plug..smelled fuel(pump is working)...check.
- cleaned grounds contact (termostat/ P/s bracked/ tranny)..check.
Just to be safe, I double check my mechanical timing...and it seems on point...although its hard to tell now that the motor is in the chasis and confirming the cam marking @ eye level is not easily visible.....so,

CAN SOME ONE W/ OR HAD A D15B VTEC confirm my M.timing. (note, camera movment/angle might be off from one side to another.


Once confirmed, I'll move onto CEL's/ Compression testing...etc.
P.S yes I've searched, and yeild no results...besides the general assumtion that the d15b is timed with the P08 marking at 9 and 3 o'clock.

Thanks for looking.

 

Also have D15b vtec and Was wondering also if i should use the 9-3 oclock marks or the 7 oclock marks because I thought the z6 used the 7 oclock mark. I put at 9-3 marks but seemed like more power from the 7 mark.

Also do you hear fuel pump priming when key in on position?

Maybe try to ohm out some of your wires to make sure your they are good because I had a no start prob with an external msd blaster 2 coil and the msd wire from coil to dizzy cap was bad. Checked lead on wire and was bad so I homemade a wire out of housing electrical wire good to 650v and fired right up. I recently learned how to somewhat use a voltmeter and they are your friend trust me. If I didnt have one I would have found my prob. Dont buy a cheap one but dont buy an expensive one wither to learn how to use one go midgrade IMO.

I comp checked engine and each cyl was 209-210 psi

 

Yes the fuel does prime, and after a few cranks, the plugs smell of fuel. Grounded a plug at each cable and a healthy white/blue spark is produced.(so I'm confident in the coil)
Firing order @ 1342.
No cel codes.
Compression tested it today and only got 125psi @ 1,2,&3.(4 sec.) The fourth had a best of 95psi before adding a few drops of oil that bumped it to 130.(sux but not my main concern now)
I held the key over for about 8 revs this time around while playing with the throttle and managed to get a few cylinder to fire(a mere stumble).but ended as soon as it began.

btw..do my pics match your timing? I can't tell if im off...




Any suggestion? Anyone?

 

Well, Ive just read that the jdm d15b vtec is to be mechanically timed with the z6 pointer @ 7 0'clock?...Anyone w/ a d15b obd1 contest to this?
(91dxvtec - thanks btw, I'll put you down for z6 cam timing)

It looks to be a difference of 1 tooth..would that cause a no start?

 

You use the 7 oclock mark. They will normally start when off a tooth but, it may depend on which way it's off.

Do you have a noid light? you might want to check for an injector pulse at each cylinder. I once managed to old half plug in the injector plug at the passenger's side shock tower and only 2 injectors would fire intermittently, spent over a day trying to figure out what went wrong.

 

Well its timed at the z1 marking. So judging by my first photo..i'm about 1 tooth retarded?
No, I do not have a noid light, but Im willing to rent/buy one, probably by tomarrow. And all injector plugs are completely on. Although, even with starter fluid sprayed into the manifold(5second spray) Yeilded no different result, and Im using the injectors that were on my z6 before it threw a rod...which were working fine.

For what it's worth..here a video.

My timing is off too then I went with the 9-3 marks not seven. check engine grounds. wont start without them hooked up. Forgot to hookup valve cover to chassis ground and had no start before so check those. And the d15b vtec is a high comp engine so I would be concerned about that man. I had a b7 at 160-170 psi across cyls. I mean like I said I had a strong 209-210 psi across the board.

 

Did you ever get this figured out , I am having the same problem. I set it exactly like yours and I have to turn the distributor like 15 degrees past the bolt holes on the dizzy to get it to start and run. I wonder if I should be using the 7 oclock position on the cam to set the timing instead.

 

 

I just tried the 7 oclock mark and still not go I have to set the distributor about 15 degrees past the bolt to start it up and run. It seems now mater where I set it, I have to set it past the bolts to start and run.

 

plugs in the right order on the dizzy?

 

ur timing is off if u cant get it to adust in spec of the slots. seems like ur a tooth or so offu can also set it opening ur dizzy setting it in the middle of the slot. turn the head until its directly over that plug contact. do ur compression test warm with the throttle wise open

 

Sorry..I did get it to start. Don't ask me what it was, I myself an still confused.
I tried the d15b dizzy and at the first crank it was @ least firing 1-2 cylinders...held the key over for about 20+ seconds while giving it throttle(force of habbit/felt like it helped tho?) and bam! Fired..rough, but eventually evened out.
And for closure so that I could definitively say what was wrong...I went back & tried the z6 dizzy and it too fired? WTF?!? Been using it since.

Hacksaw777..It does sound your timing is off..9&3 or 7'clock..it should not take that much adj @ the dizzy to fire.
