pcm

Hello everyone, So I bought a 2004 Mach 1 as a bit of a project and it was quite the task getting it back up and running. But now im running into some tuning issues. So the guy who always tunes my mustangs is in the process of writing a tune for my Mach 1. Well when I bought the car, it had...

Hi all, 1994 V6 Mustang, bone stock electronics. I was driving and the car completely shut off. On the side of the road I had a crank no start. After a tow home I see fuse E in the engine bay is blown and has continued to blow as soon as key is switched on. It controls - PCM - Fuel Pump - O2...

What's the best way to clear codes in the instrument cluster? Trying to figure out a pats issue. Found out the pcm in the car was not communicating with obd2 so I swapped a donor pcm and instrument cluster that came with the car in. Was told the cluster and pcm were out of the same car by...

Hi all. This is my first post to the forum. I did try searching for old posts to answer my question.. But could not find anything after a few minutes. I purchased a turbo kit for my 2006 Mustang GT. I would like to go the Megasquirt route for tuning if possible. I have a friend who does MS...

Hello all, I just installed a new PCM, with programmed VIN, into my '96 GT, manual tranny. I have an unpaired SCT X4 tuner I want to connect to the car. But, the tuner can't read the VIN through the ODB2 port. I hooked up a scan tool and have the same problem. Both the scan tool and the tuner...

Hello, I recently got flagged by the State of California for Smog issues on my vehicle. They are requiring that I put the "factory" tune back on my car. The issue is that I have a true 2002 Stage 2 Roush mustang and I am not sure what the factory tune is! Is it still a basic 02 GT Tune...

Hey all, i'm having a no start issue on this GT I bought and the problem is dodging me. I'll try to be as detailed as I can about what's going on and what I've done so far. The car will crank but doesn't start. The PCM power wire (V) is only getting .46v. All the grounds that I've checked so...

Hi all! Long time stalker, first-time poster. I am going to be putting my 94 V6 under the knife and converting the blown AODE to a T5. My question is do I need to have the PCM reprogramed/ swapped completely to accommodate the manual? If so, any thoughts about FS1... I've heard good things.

I noticed my tps and other sensors like iac and others are giving a 12 volts read on my multimeter with key-on instead of the usual 5 volts it goes as high as 18.5 volts with car on! I'm guessing those ("missing") 5 volts show up eventually when I turn the car on? But wait , how can that be... I...

Initially the car would run and then would stall after about a minute, (or as soon as the ac was turned on). OBD2 would give me Code 1233 (fuel pump dvr mod disabled/off line), and P1516 (intake manf runner ctrl input error (bank 1)). Checked the connectors to the fuel pump control module, and...

Hi, I have 2016 Mustang GT with new Aluminator crate engine installed. (New engine harness). The engine is working fine but we have misfires in high RPM, while trying to investigate with have noticed that we cannot communicate with the PCM (All other modules can be communicated fine). What can...

Hi everyone, I am currently having issues with my Mustang 2005 ENG:4.0_Liter, I hear a knocking noise under the hood every time I am at a stop light pressing the brake and yesterday it suddenly stalled and had to shift back to parking and turn it back on again, and not the first time that this...

I have made previous postings about my car (1994 cobra with X303 Ford Racing Engine), but nothing has really come out of it. I think the problem back then was CEL codes. As many problems I have had with this car (very strong gas smell failing emissions) the car would not pull any CEL codes. Well...

I bought this car a few months ago. Turbo car built. Who ever did the wiring obviously messed something up. I had a no start issue where the theft light was flashing. Initially I thought it was a pats issue or a bad key. Had a locksmith come out and he confirmed that was not the issue. Well last...

In the last six months I've replaced the ccrm fpdm fuel pumps and my battery. So I have power going to my evap vent valve and power going to my pumps, but the pumps won't kick on because there's no power going to my fpdm, because of this I've replace the fpdm and the ccrm, what sends power to...

I have a '95, base model, 3.8l mustang. Over a year ago I was having problem where, I would accelerate and car would start going, lose all power for a second, go, lose power, come close to stalling and so on usually 3-4 times. Lost all RPM's, speedometer bouncing, all gauges bottomed out and...

Hi, my name is Justin. I own a 2002 Sonic Blue New Edge Mustang GT. This is my third Stang. I've had it since July of last year. I need help with a PCM swap, But I'll start a different thread for that. If that's ok.

I have a 2002 mustang V6 automatic. 1 week ago I changed the alternator. The car was running fine for a few hours then just died while I was driving. The car would crank but not start. The lights worked et . Where the mileage usually is was dashes. After checking the wiring my boyfriend came the...

Ok guys, my back is up against the wall and I’m hoping this has happened to someone else that was able to itdentify the problem and get it fixed. I was driving home two months ago going about 70 mph on a relatively flat road when all of a sudden my 2007 Mustang GT seemed to shut down, but the...
