Thread: no spark no injector fire and no hair

its been wks now since I crossed my battery cables. My s13 blacktop had no fuel pump or spark but would crank over fine. With help from u guys we decided I needed a new ecu. Ureika!!!! New ecu brought the fuel pump back to life but now I still dont have spark or firing injectors. I'm thinking ignitor chip or my CAS now. These are expensive so I was hoping for feedback to let me kno which I should try first.
Oh and all wires and fuses have been checked and are good.

pull out your crank angle sensor and try turning it with the ignition on. if it fires the injectors then it is working. judging from what you're saying, though, it isn't going to work. have you checked your fusable links and all relays/fuses?

I will try the CAS test when I get off as for the fuses and fusible links they are all good. I spent the last two wks double checking and even called wiring specialities who did the harness and made sure I didnt miss any fusible links. I was told by a guy at enjuku that the ecu ground signals to the coil packs and injectors both pass through the ignitor chip. Is this true?

if the CAS is in the distributo, pull the distributor and turn the wheel and see i the injectors click and you hear the fuel pump come on....also check for spark at the coil to see if the distributor is getting spark to the distributor, check the resistance of the coil, there really isnt any way to heck the iginiton control module other than if you ar getting spar at the coil, unplug the iginiton module and see if that spark stops, if it does then your iginiton module isnt bad.

like others said sounds like you arent going to get spark, but in the event that the CAS isnt bad and you POSSIBLY get spark at the coil, it could be you ae getting some sort of resistance iterference and its making you not have spark.

i woulddefinitly put money on the distributr tho, but in thecase that the distributor isnt bad...then i would keep checking other things...the iginiton system isnt that but and checking it is pretty quick you narrow things down very fast
