96 Gt Doesnt Run

[snowcolt]

ok. not my car, but my brothers..

he was driving and it just died. put fuel in, doesnt do anything. change fuel pumps still nothing.

kept blowing the eec fuse.

so we loacted the short, was from the gauge to the ects. fixed it doesnt blow fuses now. but the theft light is on. throwing 1:6 code.

we changed the ccrm out. still fuel pump doesnt work. dont think that the pcm is getting power and its throwing a theft alert. or ignition?

anyone?

do you have a spare key? if so try it... there might be something wrong with the chip or whatever inside the key so your theft light is going on, and stopping the car from turning on

 

[snowcolt]

unforantally. no. but i found a thing for tarus' for testing the ccrm. going to try and do that. and see if its getting the correct voltage and stuff. try to revert from paying alot of money, towing back and forth and having keys made and what not and not even be the problem

For a 96, you can make your own key.. There is a how to on here somewhere

I got a key from ebay, had a local hardware store cut it, then I programed it. I had 1 working key and programmed the second.

i think his ignition maybe messed up. the ccrm isnt sending anything to the pcm. and he said pin 8-24 isnt getting power on the ccrm....

 

[snowcolt]

anyway to "force" the fuel pump on. i read i think on a f150 you can ground out pin 6 and 18? and itll kick the pump on

on and checking pin 18 on the ccrm. we were checking grounds and everything reads below 2 ohms.. but for pin 18 its reading 86...

and pin 13 has no power....

any idea what in the hell is going on?

STOP!!! CCRM pin #8 (wire color Y) is powered DIRECTLY from the EEC fuse. So if no power to CCRM pin #8 and #10, the EEC fuse is blown.

In many owner's manuals, the EEC and fuel pump fuse are backwards. Bottom line, the EEC and the fuel pump fuse must both hold without blowing.

Suggest going back and double checking your work before replacing any more parts.

A full set of wiring diagrams may save you a ton of headaches. If interested in getting a copy for yourself, I maybe able to help. PM if interested.

FWIIW, CCRM pin #11 (wire color Y) is feed directly from the fuel pump fuse. There should be +12 volts on this circuit at all times.

As far as a way to force the fuel pump to run, ground CCRM pin #18 (LB/O). However, if there's no power to CCRM pin #11, it won't matter.

Gets cobstant power to 8, 10 and 11. As soon as you turn it on it shorts out we have unplugged pcm made sure grounds are Good on ccrm.

Soooooo this means there is still a fault down stream of the CCRM. Have you confirmed which fuse is blowing (PCM or fuel pump)?

Are you aware that the CCRM also powers the motor's VPWR circuit? This is the RED circuit going to most sensors on the motor. What have you done to rule out the sensors as the fault source? Sensors such as the O2 heaters, TPS, fuel injectors, EVAP solenoid. Basically any sensor powered by a RED wire.

Any recent exhaust work? If so, look for wire harness damage to the O2 sensor heater circuit.

Regarding the original problem found, are you sure that it is fixed?

 

[snowcolt]

Fixed. Thanks alot. Wire was shorting out on the exhaust. Thanks alot!!!
