Hello everyone I’ve recently purchased this car for a great price, the last owner I believe tried to repair it himself and gave up.
I’ve found a post on here very very similar to mine found here I’ve tried all the stuff on there including a new PCM AND tried what Ben answered.
I have alldata and have wiring diagrams so I’ve been tracing circuits left and right.
I’ve found that pin D12(pink and black wire) on connector x2 on fuse box is only getting 7.6 volts. I also traced that wire to pin 1 on the PCM.
I know that relay 33 POW/TRN circuit powers that and the injectors as well as ignition coils are powered from that circuit. I also am getting 7.6 volts at the relay.
What feeds relay 33? I can’t seem to find it
UPDATE: when I checked the resistance between pin D12 and pin 30 of relay 33 terminal I get 4.7k ohms this is definitely a problem right?
UPDATE:I found the PCM issue... it was the ground cable that ground to engine block near then starter. Now the issue is it cranks but no fuel injector pulse, also I am getting code p1682.
