Bad ECM?
Reply #51 –
Well gentleman, I tried pulling the codes by jumping the Sti and sig rtn, but I got nothing but. Steady volt lamp with koeo. So I then tried pulling them by grounding the sti to ground, on the negative batt terminal, and I was able to pull 7 codes, and then 2 continuous memory codes. The 7 codes are as follows:
22- MAP out of range
35- EGR pressure feedback regulator circuit
51- coolant temp sensor out of range
53- TPS input out of range
54- ACT sensor
67- Neutral Drive Switch Circuit
95- Fuel Pump Circuit problem.
Then I had 9 seconds, followed by a blink, then 9 more seconds, then I got a code 95. Fuel pump circuit problem.
So, I found it quite obvious there was an inevitable issue with pin 46, just as Softtouch said he was afraid of. I figured since the sig rtn wire goes to the MAP, TPS, EGR, ECT and ACT sensors, and they all are throwing codes.....I decided to pull the computer. I opened her up, and sure enough, through the overwhelming stench of burnt electronic smell, the infamous pin 46 circuit was burned. (I'll put a picture up of it then) I took the voltmeter, put it on continuity check, and pinned the ends across the burned gap, just to make sure. Needless to say, I go a big fat O.L on my meter. So I think I will try to solder a thin 28 gauge wire across it, like I saw on the corral I belive it was. Any thoughts? Should I try mending it to save the $$ or should I take it to advance and get a remanned computer? Thanks for your continued help guys. I really appreciate it.
