Cranking and turning but not starting

Hey Guys.

So over the last two months I would say about 6 times, I have gotten a crank but no start on the first turn, then it would start right up. Then as of about a week ago I noticed my rpm gauge would flicker while driving every so often. Then about two days ago, it along with the battery gauge would flicker together intermittently while on the road. Then all of of sudden this morning, it's cranking and turning, but just won't catch.

So I'm not sure if I'm using the term turning correctly, but to be more precise, right after the crank, it turns over/ an initial start, then it dies. And then crank is only a split second.

Twice it has died while driving over the last three months while coming out of 1st gear into neutral coming to a stop, but it started right back up. I also notice when I am in 1st gear and I go into neutral, when I come off the gas my rpms would drop down to about 600, and kick right back up to normal around 850. This has been happening for about 6 months or so. But strange thing is, it would only do this about 50% of the time.

One other thing. Before today, when I would turn the key to the on position, my fan, battery and fuel pump would all engage. Now, these only engage when I actually turn the key just before it cranks.

Things I've replaced over the last six months:
Ignition Module - tested it today just to make sure and it was good.
Alternator - tested at Autozone while it was running.
Battery
Coil
Solenoid
Fuel Pump
Fuel Filter
Plugs and Wires
Timing - about a year ago.

87 2.3L Non Turbo
5 Speed Manual


Would appreciate any insight.

Well crap you have replaced everything I would start with so that makes it hard for sure. When was the last time you tested the alternator and battery and how new are they both? If something is draining on the battery it can make it go bad pretty quick and also alternators are sometimes faulty so that is why I ask.

So you hear fuel pump kick on still while your trying to start it right? The no start on fist turn and dying randomly point me to a fuel pressure issue. Could also be a alt/bat power issues as well, but I would lean more towards lack of fuel.


Past Mustangs in order and color of text.
(1.)2000, (2.)2004, (3.)2006GT/Auto traded for (4.)2006GT/Manual, (5.)1996, (6.)2011GT, (7.)2003GT, (8.)2006GT, (9.)
2013 Boss 302, and (10.) 2002GT (I have owned a few non Mustang cars over the years as well, but always try to have a Mustang with it or come quickly back to a Mustang!)

Sounds like it could be a faulty ignition switch.

Iím going to agree on either the ignition switch or the pickup sensor in the dizzy.. when mine went bad it started like this and then the car just didnít start.. it also caused my brand new ignition module to go bad..

Appreciate you all steppin in. MustangLife I think I'll head back down and have the Alternator tested again, but this time I will take it of the car and have them test it on their machine.

heavy metal & Stustu07, the Ignition Switch is what I initially thought as well. But would the switch be causing my battery and rpm gauge to be sputtering while driving though?

Yes it could cause that.

The PIP sensor in the dizzy can also cause your gauges to go hay wire and do you have the old ignition module still?

Turns out it was the ignition switch. I went ahead and bought one right after you both posted, but of course the socket size needed was not in my set. Why the bloody hell do they even use these types of screws??? So I had to tow it to the shop, and they confirmed it.

Much appreciate Gents. Cheers to you both. :
