Ok my friends, i build a 7bolt head with a 6 bolt block, we install the CAS 1g 92 (green color) with the harness 1g 2g adapter from ebay and we swap the plug spark wires and change the position of the pins 1-14 14-15 and 15-2 i have injector signal but i dont have spark, and today I see that the check engine light dont start when i turn on the car what are the problem :ohdamn: the dsm is a gsx 95 ECU Oem 95, i dont know if are problem from the Ecu, crank sensor, CAS, or another thing.

I regard the help.
 
first im not sure but i dont think you need the older cas with the 7 bolt head i think you could use your original cas for the 7 bolt head. second, if you have replaced the spark plug wires then i would check if your getting spark directly from the coil packs. other than all that id just check all your connections man

make sure your spark plugs are gapped right
 
No cel light when it first turn the ignition should come on, then go off. Thats what mine did on my 1st dsm a while back.
 
ok ok, i we check all the ignition component and see that the CAS have diferent volt when i turn the key for star, the problem was resolved with the spark when we change the orders for wires to the harness adapter when i buy in ebay had bad the conection know i have spark the car start but when the goes to ralenti (1000 rpm) appear the light of baterry and check light.
