97 Cougar cooling fan has to stop to start car

Do you have a check engine light on ? lets try and get the codes 1st as it may be the relay / module most local part store can get the codes for free you need an OBDII reader to do so let me know what you have for codes Constant Control Relay Module (CCRM) CCRM interfaces with the PCM to control cooling fan, A/C clutch and fuel pump operation. The CCRM also incorporates electronic engine control power relay to supply power to the EEC-V system

I didn't get any codes, they said that the diagnostics ran fine and then ended at the pcm because it couldn't read??that is what they said. and no the check engine light is not on.

I would for sure seek another opinion as I do not like theirs at all
if they had said its the relay most likely to believe it
but the computer and no codes and every thing else is working
Dont think so (yet)
need more testing
start by Constant Control Relay Module (CCRM)
maybe a good used one to test 1st

I know it's been awhile, I was wondering if you solved the problem and what it was. I have the same thing happening. Any help would be greatly appreciated.

I doubt they will get back to you as it was 10 years ago. If they do then, great but let's address your issue even if they don't. Have you done anything to address the concern already or are you just at the beginning? Also, when you don't wait for the fan to shut off and just start the car does it crank and not start or does the starter not even turn over?

I have to wait for the fuel pump to prime, then it starts right up. If I try to start it before then it just cranks. The colder it is out the longer it takes to prime. I replaced the fuel filter, fuel pump and the fuel pressure regulator, and it still does exactly the same thing. I checked fuel pressure at the rail and it's 30 psi with the regulator and 40 psi when I bypass the regulator. I'm thinking either the pump I bought new (on-line) was no good, or there's an electrical or computer issue. I'm about ready to give up!

If you measured the pressure with just turning the key on and it was 30 PSI then yes, that is low. It could be the pump but it could also be an injector leaking causing the loss of pressure.

Cycle the key a number of times and then pull the plugs and see if any of them are wet or smell like fuel. If they do then you are leaking fuel in the combustion chamber.

Wow - I'll try that, thanks.
