Help. no start car is in storage and has to move

Hi everyone. I have a 1999 mustang 4.6 manual tans vert. Car was parked all winter in storage. I brought battery fully charged installed turned key and fan started at full speed and it just turns over. No start. Fuel pump does not prime at all. Back fuel switch is good. Kept trying when theift light Started flashing and then dashes displayed in the odo.

I ve read alot of other posts so I'm trying my best to figure it out.

All fuses are good at bjb and cjb.
I also pulled and cleaned two grounds at battery and one on the passenger side at the front. And I ran through the check to test ignition switch. How ever fuses f2.6 f2.35 f2.37 f2.38 and f2.41 do not have any power with key on or off.

Not sure where to go from here.
At this point it just turns over.
But I have remove car now as I'm already past my storage term. Any help would be great and thank you

For the purposes of the crank with no start the fuses that matter are F2.34, F2.2, and F2.8. If we assume those fuses have key on power THEN, The ignition switch is good and the CCRM is good.

Please see the following threads for more information.

1999 3.8 v6 HELP!! Crank no start odometer reads “———“ radiator fans on, theft light flashing rapidly

^^The thread above puts everything into practice. However the original poster hasn't (or won't) perform the power and grounds tests at the PCM. This test is necessary before calling a bad PCM.

The OP also hasn't tested the PCM by attempting to access with an ODB2 scanner/reader.

Note, swapping a PCM as a diagnostic test a bad idea which often creates as many problems as it solves. Do yourself a big favor and perform all of the tests that "prove" power to the PCM.

Note2; For a car that is been in storage for a long time the possibility of rodent damage should be considered. Have you inspected the area around the PCM and inside the engine bay for evidence of rodent activity?

If you do end up replacing the PCM here's some information on a DIY PATS option.

Thank you so much for the reply. I have read the above post.

99 3.8 v6 no start.

My car is in a heated storage unit. Nothing looks disturbed from mice or rodents. I did however put a set of jumper cables to the engine and chassis to make sure they were grounded as I have had that problem arise before in my older pick up. I will be going to the unit on Friday as I work too late tomarrow. I will try plugging in a scan tool into the odb2 port to see the pcm, as I didn't bring it with me the first go around. I will also print those threads off and work through them.

The passenger door was too close to the side wall to open door and pull trim to get to the ecu. I will have to pull car out with a strap. I will perform those ecu tests first before just buying a junk yard ecu and swaping it it with fingers crossed. People don't get it. If a short happened and took the pcm with it. Why plug in another just to turn the key and blame. She gone!

Agian than you and I will post me results.
