    '91 with no A/C anymore

    I haven't used the A/C in my 1991 5.0 GT vert since last year when I had the compressor replaced and it stopped working a few weeks later. The computer gave out a few days later and I couldn't get it back to the shop that "fixed" the A/C. The A/C blows air out of the ducts just not cold...

    Dextron 2 ATF or P/S Fluid?

    So what should I put in the reservoir for the first time and I guess through out the life of the new power steering set up? I have a 1991 Mustang GT Convertible and don't have the factory manual. Chilton doesn't really specify.

    Dextron 2 ATF or P/S Fluid?

    So whats the deal with "everyone" suggesting putting automatic transmission fluid in instead of power steering fluid after replacing the p/s pump and rack and pinion? I'm finishing up this job tomorrow and wondering if I should add Type F ATF or P/S fluid and what the difference is?

    AOD Blues

    Hey guys, I had my 1991 AOD rebuilt a few months ago by a guy I trust that had rebuilt it in the past then the computer crapped out on me. Not associated with the AOD, but it took a few weeks of testing all the possible suspects to verify it was the computer and replace it. (The long story...

    Rack n pinion/Power steering pump

    So this looked pretty easy and straight forward, but I couldn't get the jam nut loose to free the Rack. I assumed that I should be loosening it clockwise because it should be going toward the rack or engine and away from me or the brake assembly. I couldn't get it to budge after tons of DW-40...

    '91 5.0 no go. Help!

    She starts!!!! Ok, I finally got the car running after all that testing and ruling out parts I only threw one part (fuel pressure regulator) at it before I decided to stop wasting money and figure out what was wrong before I replaced another part. I went through jrichker's 6 step...

    '91 5.0 no go. Help!

    That's my biggest issue. I don't like throwing money and parts at my car only to have it laugh at me and go back to sleep. Although it is nice to know I'm not the only one that the computer has died on msisk14. The biggest problem is that the car is parked 300 miles away at my Dad's and I've...

    '91 5.0 no go. Help!

    Ok, so I bought a digital volt meter and the TPS tested fine. The analog meter I had wasn't accurate enough. The TFI also tested fine at the auto parts store. I bought a node light set and there is no flash/injector pulse. I put it all back together and tried to start again. Same...

    '91 5.0 no go. Help!

    Nope, I tested the green wire. The green wire gave me 5 volts. The other wire gave me a constant 12 volts as expected. I didn't depress the pedal, open the throttle or anything though. Should the readings be between .98-.99 volts like I've read on some Mustang sites? Is that the desired...

    '91 5.0 no go. Help!

    Ok, so I decided to rule everything else out before I deal with how I'm going to take out the TFI for testing. I tested the TPS with an analog meter (all I have at the moment) and I got a reading of 5volts. This is obviously over the 3.7 voltage limit. So what next? Should I replace the TPS...

    '91 5.0 no go. Help!

    Well several people have told me that the TFI factors in on when the injectors open and I'm assuming that's my problem. I really didn't want to mess with it but I figured if I could get it tested fairly easily and rule it out, why now. Got any insight as to what the problem was with the...

    '91 5.0 no go. Help!

    Ok, I tired to get that pesky TFI out for testing. I was able to get one of the bolts out but the tool that I bought at Autozone won't fit in the area so I can get the last bolt out. I really don't want to pull the distributor out because that scares me. I don't want to disturb other areas if...

    '91 5.0 no go. Help!

    Thanks for the input ninety15.0. I agree, the bronco computer wasn't an attempt at fixing the problem. My original computer wasn't giving me any codes and the check engine light was blinking so I assumed there were codes to be had. Plugging up the Bronco computer was an attempt to pull the...

    '91 5.0 no go. Help!

    I've narrowed it down to the fuel injectors not firing, but what would make all the injectors not fire? Any and all possibilities would be appreciated considering it's always the least likely scenario that happens to me. Joe

    '91 5.0 no go. Help!

    Good Point!! That hadn't even crossed my mind. So do you think that that is the reason the car sounds like it really wants to start but won't and with the original computer it would just crank and crank? Is that a bad EEC IV?

    '91 5.0 no go. Help!

    :bang: Alright, I've gone through the entire list and this is what I've come up with and still NO START. I decided to buy a code scanner since I have three OBD Fords. Hooked up the code scanner to the Stang and got nothing. Tested the code scanner on '93 F-150 got code 111 (system...

    '91 5.0 no go. Help!

    I've done almost everything I can think of. I'll try to keep it short. 1991 5.0 Convertible. Symptoms: Car cranks and cranks but won't start. I have spark. The car starts when I shoot starter fluid in the throttle body, burns up, then dies. It sounds great when running so I don't suspect...
