The red wire's to the injectors should have battery voltage , do they ? Test with a voltmeter . The other different color wires go to the PCM - engine computer . The PCM supply's ground to those wires when it receives a signal from the crank sensor or cam sensor . You have a bad PCM or a sensor input could be missing . Video's on youtube on testing injector driver circuits .

This sounds like a fuel pump relay.Since it cranks,that means everything input to the PCM is good.These are start relay,start solenoid,starter,ignition switch and brake safety switch.The direct output are the fuel pump relay and a relay called an auto shut down relay,which is directly activated by the fuel pump relay to power the coil and injectors.Since the 2 relays are obviously the cheapest,take a reading at both.Some makers do not have a shut down relay but I think those are mainly Chevy.The CCRM,I am not sure what that stands for.As for the battery charger,I would need to know a little more about the situation.If you drained your battery trying to start your car but wouldn't,they are not likely related.As for the fuel pump,I wish you would have researched a little more because I know it is expensive and a pain in the a** to change.Relays go bad more often although 2 years I changed my pump on my 1995 Ford Escort.Wht I'm trying to get t is to try starting with cheaper fixes first,then you won't feel so bad if it doesn't fix. :( Just a suggestion but I have been doing repairs for years and have a system worked out due to experience.Relays are the most common fail items too,as well as switches,bulbs,and many other components but if you notice,most of these items are relatively cheap.If you have any questions or need more help,just comment here and I will get an autolink to your post and reply ASAP.Good luck,Greg

Yes, there are expansion plugs (freeze plugs) on both sides of the engine block and at the rear of the engine block between the engine and transmission. There are also a couple in the ends of the cylinder heads.

With all that said, I would like to add that many times with that engine, the heater tube and connecting hoses can leak and be mistaken for a rear expansion plug leaking. I would definately check this before pulling the transmission out.

There is a tube that runs from the back of the water pump under the intake manifold and out the rear of the engine where it hooks up to the heater hose/heater core. This tube has a small hose connecting it to the back of the water pump. There is also a hole in the back of the engine block that will allow antifreeze from under the intake manifold to leak into the transmission bell housing area. When this tube or hose leaks, it often gets mistaken for a leaking rear expansion plug.

It is very easy to check for this. Remove the serpentine belt and remove the alternator and look under the intake manifold down in the "valley" between the cylinder heads. If there is antifreeze in there, the hose or the tube is leaking. Look at the picture below. Item #3 is the tube and hose assembly I am talking about. Usually, just the hose is leaking. It should be replaced with a short piece of SILICONE heater hose. On some of the vehicles, there are 2 hose clamps. On others, the end of the hose that is attached to the tube has a crimped collar on it. If yours is like this, you can fix it by carefully cutting the crimp collar off and replacing the hose using band clamps. (screw-type)

Also look for antifreeze leaking into this area from the front intake manifold runner. They tend to leak on the front runner near where the thermostat housing is located. These will also leak into the valley area and run out the back of the engine. If the manifold is leaking, chances are it is warped. DORMAN makes a replacement intake manifold kit just for this purpose because it has been so common. It is also very easy to check for this with the alternator removed.
The DORMAN part number for your vehicle is 615-178 (See second picture below)

Did you check your fluid level? If this is on a Borg Warner World Class T5 transmission the check/fill hole will be on the passenger side of the transmission. Unscrew the bolt and check. Fluid should be even with bolt hole. If not fill it with ATF. Yes they use ATF. Fill it up to bolt hole(fill it til you spill it) and replace bolt.

I am not sure exactly what your question is, but the relays in your mustang are located on either the under hood fuse box or the CCRM, which is located in the passenger side fenderwell. To do a bench test on one to see if its working, simply locate the relay in question and unplug it.Look on it's side and you will see its schematic with numbers at either end of two symbols. One symbol will be a straight line with a circle at either end and the other will be a circle with a line running from it at 45 degrees with a circle underneath it when that line ends.
Get two wires and attach one to your cars battery positive and negative terminals. The pins on the bottom of the relay are numbered. Match the 2 pins that match the numbers for the symbol with the straight line with a circle at each end(numbers will be next to the circles) and touch one wire to one pin and the other wire to the other pin. You should hear an audible click. If you do then the relay is good, if not the relay is bad.

This is the only diagram I could find for tail-lamps. The top wires are voltage, the bottom wire is ground. The brown color wire is voltage for tail lamps. The other color wire is turn or stop, depending. The turn and lower brake lites use the same bulb filament, just not at the same time. The lower brake lites are wired through turn signal switch. I don't know if diagram matches what you have? I looked at several, all showed the same thing.

did you pack the thrust bearing with grease before fitting. its always best to pack with grease before fitting. as new bearing only come with a small amount for testing the bearing, pack grease into the bearing and spin it do this fa few times and wipe away the excess off before fitting.

As long as the lights do not stay on, a broken switch should not drain the battery. Why don't you pull the fuse on the headlights and taillights?

Since it sounds like you also carried over the OBD2 connector, do you have access to an OBD2 scan tool with datastream mode? If so, you should be able to monitor various sensors to see if that offers a clue as to why it stalls. When it just spins over have you checked for spark, fuel, and injector pulse width?
