The other a day a block from my house my 95 GT died on me while cruising (luckily I was able to coast into my driveway). I tried cranking the engine but the battery was very low and would not crank. So I charged the battery and the motor was able to crank just fine but no start. I first thought that my alternator was going because a week before my battery was low and if I did a short run from my house to somewhere else the car was having trouble cranking over. So I thought it was the alternator, how ever I also do not here the fuel pump priming either. So I am not sure what the problem is. Tomorrow I will buy a voltmeter so I can test things. Also as side not I tried to check the engine codes but the car would not give me any, Is there no code for alternator and fuel pump?
If anybody has any suggestions that would be great. I do have a MSD ignition coil but I swapped back to my stock coil and the car still wouldn't start.
It could be a bad battery, dead cell.
You canít test that with a multimeter, you need a load tester.
Most parts stores will perform the test free of charge.
You should always have at least one code.
OBD 1 doesnít have codes for the alternators.
You most certainly can test a battery with a voltmeter, youre just not testing it under load. If the battery has dropped a cell, it will not read in the 12v range as it should. If its failing under load, monitoring the voltmeter while cranking will show if the battery is shot.

The battery reads 12.66 volts and while cranking it read about 6-9 volts. I checked the fuel pump fuse, also I can here relays clicking. I still don't here the fuel pump priming.
Also isn't it strange how I can't get any codes to show? isn''t there also a way to jump the fuel pump to see if it will work.
I think what is happening is very strange because I have had fuel pumps go in the past on different early 90's ford trucks and they always slowly spudder out and die. My mustang on the other hand just turned off like a switch. I even checked the fuel rail schrader valve and it seemed like it had a decent amount of pressure left in it( I think it still would have run on that) I was probably revving 2500 rpm when it shut down and I lost all power.
if you suspect no fuel, either hook up a fuel pressure gauge
or take some carb cleaner and spray it down the intake
you should be able to idle with carb cleaner without issue
this will confirm no fuel
Ok so the car would not fire at all with starting fluid. I tried several times and nothing. Is there anything that would cause the fuel pump to not prime and have no ignition? I am really at a lose as to what the problem is with the car. Hopefully we can get this figured out or I will just tow it too a shop.
supply a ground, to the far left pin of the diag connector
hold the connector with the two pins at the bottom, key in run
sorry but I am not the best with electrical, when you say supply a ground do you mean just touch it to the chassis or something else. Also the battery is probably 3 years old. could the battery be causing all the problems?
Ok update, I got a new battery so voltage should be ok now. I tried to to pull codes again and also tried the fuel pump test and nothing happened. I also bought a spark tester and i currently have no spark anywhere except for when the SPOUT connector is unplugged. I also did the TFI test found in this video here :
and I have no flickering on the coil. Also I did check to see if there is any power going to the fuel injectors and there is none at all. I have read that the computer controls the fuel injectors, so I am now thinking that my ecm has failed. Also does the ecm control the time on the clock dash pod? cause if it does my clock was flickering and went out the same day the car died on me.
