first off like to say any and all comments and suggestions greatly appreciated. so here is the problem. car will crank and crank for days sometimes start here and there. when it does finally start runs great and even on a scanner no codes. if you shut it off then you have to repeat the process of starting it again. parts repaced-----
cam sensor------crank sensor-------fuel pump----egr---new GEM-----new PCM----- spark plugs&wires&coil&pigtale. opened up wire looms for both crank and cam and voltage is good.

Welcome to the forum.

First thing I would check next would be fuel pressure and then the fuel pressure regulator.

Also, this section of the forum isn't really for Technical questions, there's a separate Tech section specific to your year Mustang. I'd ask this in there. Good luck

I have checked the fuel pressure when running at an idle it sits pretty firm at 39 to 41. I have read that it's only suppose to drop just little bit and still keep.most of the pressure and not really drop much. after I've tried to start it it will slowly drop down to about 8psi after just a short period of time of turning key off. thanks for the heads up on where to put the post. super new to this post thread stuff.

I had a similar issue on a different car. Long story short, after trying several things, the dealership's service department suggested a new engine. I ended up changing my car, as engine cost more than the car itself. It was a 20 year old car though.

yeah I no what you mean. I've spent hours on this thing and the wife is ready to call a junkyard tow truck. Haha. it just makes no sense when she finally starts and burns the excess gas off the plugs she runs great till you turn it off. I just checked all connectors in engine bay and fenders just for the hell of it still same ****. funny though cuz you can tell when she is getting spark it's like the motor has 2 tones if that makes any sense
