DB8 RHD

95 DX motor into 92 DX Chasis

Only Difference is engine harness has map wiring, while chasis has the plug which just plugged into top of TB from fuel filter.

Will just crank and crank.

Can pull any plug ground the side out (valve cover ground) and it will start up just fine.

Valve cover grounds (2) and tranny ground hooked up.

New Coil / Cap / Rotor

Been building honda's for years just at a complete loss for this one.

Former User

Is the important ground wire on the thermostat housing clean and tight?

Is the MAP sensor hooked up properly?

DB8 RHD

Cleaned and re secured all the grounds

Map is hooked up.


Kind of at a loss for what todo

Former User

What does this mean?

DB8 RHD

So Ive got it run to 2 ways which try to explain

Pull 4# plug out, plug it into plug wire, ground the side to valve cover and it will run on 3 cylinders crappy.

I also took a extra spark plug, ground it to the valve cover hooked 4# plug wire to it, it started to run on 3 cylinders quickly disconnected and plugged back into 4# and ran perfect no hesitation nor cel, but after turning off wont restart.

is your dizzy for the right motor or check timing

Former User

Currently, does the fuel pump prime and do you have spark at all four plugs using the the method you described?

DB8 RHD

Yep correct Dizzy and perfect timing.

Fuel pump primes fine every time with key

Spark at all plugs. - All new plugs

Former User

Since you have spark and fuel, check the mechanical timing.

DB8 RHD

Timing is dead on, plug wire order is right too.

DB8 RHD

So an Update for anyone who cares or has some problem

Timing dead on mechanical and belt
Gettin some spark
Fuel Pump Good
Fuel Pressure good
Main Realy good
ECU Good....

New Plugs, Wires, Cap.... Everything and wouldnt start....

3 days later, 12 hours or so and testing everything I could I finally got it figured out, no one Ive ever talked to has ever seen or heard of this problem so figured would up date the post.

For whatever reason when the car was cranking the coil wasnt gettin a solid 12v power to the coil hence making spark but weak.

The way I fixed this is running my own power wire to the coil (diode isolated) and relayed / hooked to a switch (figure safety theft measure), and now perfect starter / runner.

You could either wire it the way I did it or relay it off the starter signal wire or off ignition wire leads.

Hope this helps with anyone in the future.

well with the coil not getting the voltage it should I can definetely see why it wouldn't start. this is the same with all engines. if the spark is weak or nonexsistent it will not start.

but what is making me wonder is how you said you could pull one plug out and ground it and it would start

anythings possible i guess. glad to see it's up and running though

DB8 RHD

I thought I would add a little more detail, My switch setup doesnt power the coil 24/7 just for starting, once run you can flip it off and coil gets the 12v it needs so who knows.
