94 ATX stalling & fan/fuelpump running on & off with key on

[JMHays]

Im a first time sho owner, just bought the car. It starts and drives good for about half hr then it goes nuts. It will start by running rough like intake is taking in a lot. Then it finally shuts down. So I turn key off then back to the on position (not running) and ccrm buzzes and clicks with the fuel pump and cooling fans kick on and off. The tac also jumps up and down between 0-300 rpms. I have checked all grounds replaced battery term. I have also tried a new ccrm and no change. It seem like when it get warm it acts up!Please help!!!!!

Are there any stored codes?

 

[JMHays]

No codes

I check for codes and none came up. When I got home car was acting like it had a dead battery! So I hooked it up too my friends v8 truck and the car was still acting like it was dead! I took a small gauge wire and touched positive to the motor lift hook and it did nothing! When it decided to ark I was getting a clicking out of the relay on driver side that is in front of air filter! The ccrm was also making a clicking sound too! I have check all grounds under hood and the main on trans and nothing! Then after all of that the car made some weird sound, then started right up! Any ideas?

those symptoms occur when the pcm is either bad or not connected properly, and when the engine is not grounded properly.

I'd check all the battery cables carefully, then the engine grounds, then the connector to the pcm. If all that is good, I'd swap in a known good pcm.

Thanks I will try that when I get off work tomorrow! The owner before me put a super chip in! Could that also maybe be the problem?

Take the chip (or sh*t they are about the same thing) out because 1. they're useless and 2. if it loose it will cause all of your symptoms.

That was exactly what my 95 atx did when the chip went bad. Pull that pos chip out of there. I changed the fuel pump and and ccrm before I figured out it was the chip.

Do I have to put anything to replace of the super chip? Is there any other chip that i can put in that will help performance? I'm a first time ford and a Sho owner any info will help me a lot! Im more a Honda/Acura person but really liking the Sho and hoping I can get this car running good with all your help! I will pull super chip tomorrow and keep everyone updated! Thanks for all the help guys!

just toss the pos chip and see if all your current problems don't go away.

I think it was the super chip I pull it out and ot started but I still have to drive it to see if it's acts up! Other then that it's running good! I do want to know, do I need a special harness to put in a after market cd player?

 

[JMHays]

I drove all day and no problems! That super chip was bad thanks for all the help! Does anyone know if I need a special harness to put in after market cd player?

you can get the right connector for any new head unit at Best Buy, Car Toys, etc. so it plugs right in. should be less than $10.

Just wondering if there is anything else done to your car besides the chip. Is there anything that needed the chip, like a C&L maf for instance?
