i have a 91 hb with a obd-0 b16a swap. the guy i got it from really messed up the wiring, so now i'm stuck tring to figure out a ratsnest. it was running until recently it died out. lost spark and now the mainrelay clicks fast. short little clicks. i checked the main relay, coil and igniter all seemed ok(i'll retest again to make sure)also replaced them with other known good ones. it makes me think somthing shorted out or is worn out. i'll check the igniton switch here today, it looked kinda janky when i put it in.(theft rebuild project) anyone ever had this happen with the main relay clicking? any suggestions?

done that twice and replaced with a known good one. any other ideas?

 

hmmm. can u explaijn ur symthoms a litle more in detail of what the car is doing

 

check engine light studders in seqence with clicking,also real dimlike something is shorted to it. goes normal brightness with main relay unplugged. ecu light is also on constant. not throwing codes. no spark.

 

i've grounded out c11on the ecu plug. the MIL ground. and the check engine light works ok now and the relay quit clicking but still no spark yet.

 

well. the main relay might click, but that does not mean it is working properly. if you used and obd0 harnes meaning that it should be almost plug and play. ig you soldered any wires check them. believe or not these are comon problems. this happened to me last year. i thought all my solders were good, but it turned out ne of my wires was hitting the chassis. just try changin the main relay and try and see if you can get a ignitor for your dizzy. unfortunatly there is too many possibilities for the problem you are trying ti figure out.

 

check all your grounds

 

check the dizzy wires, there might be a break in one , thats what happend to me

This is what ur problem sounds like, when i did my swap i had the same issue and i found the ground from the tranny to body to have a bad ground there but i would check all urs even if that emans taking them off and using some sand paper to make that better connection.

 

check the ground at the thermostat housing
