Looking for ccrm problem causes.

[SHOCH]

Long story short, running hot on the track at convention, car died.
Hamal and Fonz dive in and start, Steve and Kurt say ccrm, Brian uses tester on ccrm, it's bad and he hands me a used one. Put in Brians CCRM, runs like new all day and week. Andy drives it back to Chicago for me w/ no issues. I drive it a couple times no issue. Drive it to store and back with one slight hiccup/miss/burp when I let of gas coming to red light but recovers and runs fine.
Park in garage now no start.
KOEO test
Two Codes for fuel pump, no sound from fuel pump doing ground test.
What I Don't want to do is burn up another ccrm, I want to check things that could be causing it. Maybe Brians just dumped too.
Thoughts? Things to check?

Bad fuel pump causing high amp draw and cooking CCRM?

I had a problem kinda similar. Car would die, then be fine. Then it died and never started again. I changed out the CCRM but it still didn't fix it. Fuel pump wasn't running. Then i check the fuel pump housing and find this.



The ground had shorted/melted and it wasn't making contact. I would check out your fuel pump assembly and see if something similar has happened. I just replaced the whole unit and it runs good now.

(Edit)

Also check voltages at the fuel pump, mine was reading good numbers even though it would not run.

Beleive it or i had a short in my low water sensor,that cause it to stall call that blew a small fuse in the box under the hood.i think it was to the fuel pump.

No, that would be the IGN COIL fuse on a 93-95 equipped with an ATX... It is very common.

I think that was my CCRM actually, or Brian has mine.

Yours had the screw broken off in it, thought Brian gave it back to you.

You can force the fuel pump on at the DATA connector on the firewall. Just turn on the key and ground the appropriate terminal. This grounds the relay in the CCRM and should turn on the pump.

Are you still a go go Tommy?

...ccrm's still working, cars still starting, running, all that good stuff?

 

[SHOCH]

It's running now, almost made a thread called "I can't seem to break my car".
It quit a few more times on me so i changed the cam sensor, quit again but started after a few push and pulls on the harness and taps on the ccrm. The old cam sensor was put on in the parking lot in New Hampshire by Bab and was a used one.
Not sure what it is, keeping the ccrm Kirk brought me in the trunk and driving it all over, drove 3 hours yesterday going back and forth to Adam and Michelles yesterday, ran fine. I dunno, damn 18 yr olds, they just don't listen when you yell at them.

Thanks Paul.
I did this before I cut the hole in the floor to check the contacts.
