D15b7 no spark?!?!

[fightrice]

Alright i just bought a 89 crx with a d15b7 swaped in. Im not getting any spark off the distributor. Guy i bought it from said that it was a new distributor. the rotor and cap plugs and wires are all new. Is their any ideas out thier anything i can check? All help would be appreciated

[RBS]

any CEL's? check your wiring and if you can change out your ECU

[fightrice]

if i go to replace the ecu will i need the one that matches the crx. or one that matches the motor in it.

check fuses, recheck the distributor and the internal, check the igniter, ecu, and check timing.

igniter, coil, ecu, cap, rotor button, or bad ground 1 of them is fucked up.

thanks for al your advise guys i greatly appreciate it. il keep yall updated and let you know which one it is. Now another question. It is using the Si harness on a HF and its using on the Dx Eg motor. Could that be a problem? Does anyone know a website wherei can look at the wiring digram of the ignition system

[BlackDubs]

The Si harness shouldn't be a problem. Its almost identical, since its already a MPFI swap. Like a few ppl stated above check all of the fuses, grounds, internals esp the ignitor.

alright well i went out their and tested everything to see if im even getting power. Well im getting power all the way off the coil inside the distributor but its ust not making it to the rotor. So i went out and got a new cap and rotor thinking that the cap wasmessed up. Still nothing. im thinking bad ground

[green91]

the main ground that causes problems is on the thermostat, check and see if your cel turns on for a few secs when you turn on your key. if the light does come on the ground is fine.

you do need to be using the original engine harness for the car, dont mix and match harness because they are often pinned differently at the shock towers even if they plug in.

try taking off the cap and turn the thingy around, sry I don't remember what its called but there are only two ways it can go on the cam, it might be upside down.

[green91]

it can only go in 1 way, the 2 teeth are offset for the distributor. typically the shaft for the rotor has a flat side and they also can only go on 1 way.

[Master Shake]

try the main relay.

coils are ground switched, if it has power, see if the ground (at the coil) pulses when you try to start it. i imagine it won't, but if it does, get a new coil.

you never mentioned the basics though, you should start there, does the computer have power and ground?
get a wiring diagram and follow the circuit down from the ecu.

damn, i just found that website and it kicks ass...
