97gt no start

[project97]

i have a 1997 gt just finished putting in a 2004 4.6 using the 97 gt harness and computer,
the starter wont kick over with the power and ignition wire, only with jumper cables directly to the battery any tips on fixing this ?

bad battery?

Does everything else in the car have power? Or is everything dead?

 

[project97]

i have power to everything else and i tested the battery

Check your fuses. Then check to see if power is getting to the starter. It sounds like something is disconnected or cut.

fuses are good, im not getting any power to the starter wires, i swapped out relays and still nothing
the ignition switch was good before i pulled the motor,

Hmmm, did you trace the wiring back from the starter to make sure all of them are good? I'm about out of ideas. I wonder if it could have something to do with the PATS anti theft? My understanding of PATS is that the starter will still crank, but the fuel pump won't come on. That might be incorrect. I'm not the best with the alarm systems.

EDIT: I just did a quick search and apparently the PATS system can cause your problem. You can get that turned off in the PCM by a tuner I believe.

most times the theft light blinks while trying to start it, but the fuel pump comes on, what kind of tuner would disable this ?
im picking up a optima yellow top just incase it is the battery and a new starter power and ignition wire tomorrow out of a 96gt,
the starter is new

 

[project97]

what type of optima battery does everyone get ? and what size

If you can jump the car and everything works and the car runs, I doubt that you have a bad starter (cause it started) or PATS problems cause it still wouldn't start even with a jump if that was it. I just think your battery is bad but you said you checked that.

My car acted like that once, but it was a corroded ground cable. I hadn't thought to look at it until a guy I work with mentioned it.

 

[project97]

getting a new starter power wire and battery tomorrow too see if that helps
which ground was bad ? and if i can jump the starter theres no problem with the pats system ?

 

[96redgt]

Actually it was my negative cable and a small ground cable coming off of the side of it. On the negative cable, I just slit the wire back to the point I found good copper, cut it, then reattached it. I did the same with the small ground. I still haven't gotten around to replacing it yet..... But it actually did it to me while I was at work, and I was stuck there until we figured it out...

 

[project97]

il try that tomorrow and see, this is the only thing holding the car back from driving after i just put a new motor in it
and i really want to drive it lol

 

[project97]

if its not the battery and i get a new starter power ignition wire what else could it be ?
how can i bypass the pats system ? i only know how to bypass GM ignitions

for tuners i know the sniper special forces tuner can disable PATS. I had to disable mine when i get a new ignition and it works.

how is it as a tuner ? is it good compared to the xcal 3

 

[karrarararararar]

i've got it and really like it. I've never really heard anything bad about it. It offers end-user adaptability that some of the others don't offer (can't be too sure as i've only dealt with sniper). Here's a link with a lot of good info and is a good walkthough.
