    1993 sho electrical issues

    I'd start by checking grounds (specifically the PCM's ground and the DIS via the intake's ground wire) and codes. Do you know if it's losing spark or fuel when it dies? Does it start after cooling off again or does it not seem to matter? (I haven't read your previous thread, sorry if you've...

    Is it possible to do a straight swap of the stock sub amp?

    It's possible to do, the results may not be the best compared to running a new head unit with sub output direct to new amp. The output from the factory primary amp which plugs in on the right side of the sub amp contains 3 wires. One is your remote turn on 12V, the others are +/- low level...

    97 SHO Making A New Noise

    Sounds like something at the serpentine belt level. Welded cams should be good unless the welder did a poor job, do you have pics of the weld job when it was complete? This sounds more like a tensioner on its way out or one of the belt driven accessory / idler bearings.

    93 PCM Question

    Yeah - it was pretty easy driving running 55-60 for about half the tank since we were driving country backroads. 435 miles of confirmed GPS miles. Stuffed 12.75 gallons in (always can fit about a gallon more then when it initially clicks off, started trip with tank stuffed full and consequential...

    93 PCM Question

    Unfortunately not. Wasn't terrible to drop, came down real easy. Was 3/4 full tho so it was a bit on the heavy side. Shoutout to the awesome employees at the store, they came out and started helping me. Brought out any tools I didn't have on hand & a second jack for lowering tank. The guys were...

    93 PCM Question

    Just an update - drove 1,500 miles this weekend in the SHO and she did great (outside of a weak fuel pump I changed in an O'Reilly's parking lot on the way back home). Even got a record 34 mpg when driving sanely. Knock on wood the PCM issue is fully resolved. Thanks for all the help guys!

    93 PCM Question

    Received my report today from module experts. Original PCM failed due to leaking capacitors, it's been repaired and shipped back to me with lifetime warranty. They could not find evidence of any external problems leading to failure. Might of just had bad luck with the used replacement I got...

    93 PCM Question

    Shipped off my original PCM to moduleexperts.com today. They're going to see if they can isolate the circuit and give me an indication where the damage came from.

    93 PCM Question

    Agreed. If I find a place that will perform the repair I'll follow that lead. So far the couple places I've reached out to won't repair them or haven't replied back yet. Will follow up with phone calls if I don't hear back in another day or two. Take a quick look at the attached photos, it...

    93 PCM Question

    This is the company I just bought my latest from. Haven't reached out to them specifically on rebuilding though. UPDATE: Asked them and they replied stating they don’t rebuild or perform PCM repairs for customers.

    93 PCM Question

    Yeah, tried that on about every connection I can find. Think I’m gonna pull the intake when I do plugs and wires just for the extra space. I’ll get a better look at the PCM harness at the same time and see if anything else stands out.

    93 PCM Question

    Hopefully. If its any clue the moment the issue started on the replacement PCM I was driving down the highway running about 45-50mph in 5th gear, higher load and lower rpm. This is when the engine suddenly bucked and ******, CEL came on immediately and then stayed on. Misfired and smelled...

    93 PCM Question

    Yes, that's correct. I took a pic of my jumper just to be sure, checked that a few times myself as well. Order of events: 1. Plug in jumper, 2. Turn KOEO (key on engine off). CEL stays solidly lit, fan immediately runs on high and fuel pump stays running as well.

    93 PCM Question

    I’ve not been successful pulling codes once this PCM started failing. CEL turns on and remains solidly lit. Doesn’t ever blink or turn off. Fan stays running on high and fuel pump runs continuously as well. It’s as if the PCM ignores the jumper once it gets to this type of failure. Good to...

    93 PCM Question

    Update - New PCM started showing signs of failure after driving about 50 miles. Was almost back home from work when I felt engine power go down, CEL came on and exhaust started smelling rich. Shut off car then moved ignition to KOEO position. Check engine light came on solid - this time fully...

    93 PCM Question

    It was the PCM. Got the spare X2J and installed it tonight. Everything works perfect again. Thanks to SHOSource for the good parts! (Got a spare CCRM just in case - haven't installed it..will wait until needed.) Thanks for all the good troubleshooting info everyone! Does anyone know if there's...
