on that year vehicle or any vehicle for that matter . ABS has nothing to do with power brakes . Behind the master cylinder is the power brake booster , vacuum controlled . ABS is a system all to it's own . Think you may have thing's mixed up . You may have a vacuum leak or the brake booster is bad . Is the ABS light lit on the instrument cluster .

You have a failing fuel pump, replace the entire fuel pump module.

I am not sure if this year has the IOD fuse, but if it does it will be at the rear of the engine bay fuse center, it may have a little yellow handle.

40 foot pounds is good. But use locktite on each bolt.

Your fuel tank level sensor (also known as the tank float assembly) is failing. This usually happens due to corrosion or other contaminant getting into the potentiometer in the assembly. These can be removed and cleaned, or can be replaced, but it's a bit of a job and usually requires removal of the fuel tank itself.

you should have vehicle jacked up again to makesure that when it was lifted before to do those other repairs that whoever lifted it up do not put lift arms on heater tubes running under vehicle and possibly pinching them off cause poor coolant flow causing heating issues and possibly engine runability issues.

Can try a few things. I'm going through a similar issue on my 98 dakota right now. 1. Is the temperature gauge on the dash showing the engine getting warm If not, may be the temperature sensor. Is the electric fan working right. Does it shut off or stay running? There is a relay an fuse for that also. 2. Feel the hoses. They should be rather hot to the touch. In fact, the coolant should be about hot enough to burn you. If after running for awhile they're still cool or just barely warm, I would indeed change the thermostat. 3. If everything feels hot, you could try flushing the heater core. You'll see 2 smaller hoses about the size of a garden hose going through the firewall. They are to your heater core. It may be clogged. Basically you cut the hose and hook a garden hose up to them flushing water through it. If the hose gets stuck on the metal tubes, just cut it off. Don't grip it tight and twist with pliers. Those flimsy metal tubes will collapse then you have a bigger problem.

Are you getting spark to the plugs?

I would check the ASD and fuel pump relays to see if the coil and fuel pump is getting voltage. Then you may have to figure out if you are dealing with a no spark or a no fuel problem to proceed.

check engine compartment fuse block the cover should have everything listed on the bottom of it

I have seen similar problems but not exact...First of all / Have you ever changed your radio ? Do you know that it is not getting hot and shutting itself off ?...I have seen the temp.gauge be faulty and make the vehicle think it is hot and shut itself off...and be sure you have a good alternator and battery...also make sure the cables are good and tight...I have seen a loose ground cable cause the same thing also..The negative cable being loose will cause an ECM code that is false...Be sure they are both clean and tight...Hopefully you disconnected the battery when you changed the computer...If not ...Disconnect the neg.cable and allow it to reset itself...It may to to be just reset..Hope this helps..Metalpoet

Hi, Sounds like you need a radiator flush. If the radiator is plugged up it can not cool the engine properly. Have it cleaned out and it should work fine. Good luck.

What is the Fuel Pressure ?

You'll have to go over it and makes sure all the wiring harness is hooked up right; if it has ran since the engine was put in it may just be a bad connection, it could also have a bad module on the computer causing this the coil pack gets its main power from the pcm,and its possible its bad. Also I suggest check for any blown fuses also, a bad ignition switch will also cause this.

Keep us updated.

Hi, the idle air control valve is on the throttle body held in by 2 bolts. You will need to remove the air ducts to access the throttle body. See picture for the location of the valve/motor. Sometimes the valve is just dirty or the passages blocked by gunk. When taking the valve out, try to save the gasket. After taking the valve out, check the passages and the valve itself for dirt/blockage. If it's dirty, try cleaning and reinstalling before you buy a new one. Use the old gasket, if possible.

This is likely a bum BCM ( body control module) which also acts as your complete fuse block. This will be on the very left of the dash board either with the door open and behind a panel or under the dash. You can usually get a used one from a local salvage yard. Be sure to match all numbers that are on the unit itself or it can effect the accesories you have by causing some not to work. If you need instructions on removal, let me know.

check fluid when hot, engine running in park, if low add a little at a time through the dipstick tube. yyou'll need to dip, clean,dip several times to get excess fluid still going down tube out of the picture.

It shouldn't affect your brakes. It will affect heater operation and will cause a vacuum leak that will affect engine performance and possibly cause the check engine light to come on. If you can, replace it with a rubber vacuum hose and get rid of that hard plastic stuff.
