[QUOTE="Quarter Horse, post: 1210166, member: 18844"] Ok, Sorry Guys I'm Really NOT trying to be a Thread Whore but my Fan issue just turned into something A LOT worse!!! :( I figured it would just be easier to start a new thread so People didn't have to read through unnecessary posts. So today I took the 95 Stang to Work like Normal(The Fan has been acting the same.... With running kinda erratic and staying on right from start up), But here's were things get WORSE! On my way home I did a quick stop @ the Bank, Came back to the car and fired it up. It shot up to about 2200RPMS and then started to idle hunt Very Badly! I was only a few blocks from the house so I figure I will limp it home. The drive home was quite a PITA, anytime I pushed the clutch in it stalled, it would start right back up but I kept having to play with the Throttle to keep it running.(Almost like it was in limp mode??) Engine felt like it was running on 6 cyls and was putting out a Horrible smell (Almost like when gas goes bad..... But I know that's not it, Been on the same tank all week). Not sure if it was in Limp mode and the CPU is just really Retarding the engine or what??? The Check engine light was on all the way home from the bank. So, Once I got it in the Drive way it was staying running (Barely) so I looked the engine over the obvious stuff and sprayed Carb Cleaner around Vac Hoses to see if there were any Vac leaks and all checks out ok so far. From there I shut the car off & Pulled codes, Here is what it is coming back with; 556 - Primary Fuel Pump circuit failure and then in the Stored Memory; 512 - Keep Alive Memory test failed (This might be from me previously pulling the wire during the code reading process to erase the stored codes? IDK???) What do you all think...... Fuel Pump is bad, Dizzy going out? PLEASE HELP, I have No Idea where to go from here????? [/QUOTE]
