I have a 97 ex coupe with gsr swap and am having problems with spark. I got the car swapped and the wireing butched. I replaced the engine harness with a 97 dx harness from a stick and ran all required vtec ect wires as per faq articles and searched posts. I get no spark at all and when i got the car the wireing was distroyed and i am wondering how to tell if the motor is obd2a or obd2b and it appears the dizzy may have been re pinned but will a repinned obd1 dizzy work on an on a 2a motor and 2a p72 ecu? The old setup had an obd1 ecu with jumper and the dizzy was pinned into the obd2a harness. Is there a way to id the dizzy aside from the clip also to id the head obd??
Any ifo would help and thanks in advance.

 

also already replaced the coild nad ignitor in that dizzy and timing is ok. motor is jdm and crank sensor mod is already done with the ecu side of the harness.

 

maybe its the harness your running..

 

yeah i think your harness and also im not sure if that harness is supposed to be ran with a GSR

 

Its an obd2a civic harness and should be plug and play with the exception of the v tec wires i had to run, At least that's what all the faq and searched articles said.

Does the fuel pump prime? Any CEL codes? Does the dizzy Blk/Yel wire have battery voltage at the coil and igniter when the key is turned to ON(II)?

 

Pump Primes, no cel and ill check the blk and yel wire now.

 

By the way, you may need to crank the engine for 20-30 seconds to throw a CEL code, if there is a sensor fault.

 

Thanks I did not know that.

 

Got it running it was a wire that had come unpinned on ecu side. thanks for your help ronj@ht
