needing help with eletrical system on a 1995 beretta?

Question

I have a 1995 beretta. The motor is sound and runs great. However it does not want to stay running. I have replaced the alternator on it and the battery and other smaller parts. So far its a no go. So what i am asking is how do I test the eletrical system to figure out where the short can be at? I know the abs light has been coming on since this has happen and I the radio light comes and goes but it has always done that. I am in plymouth indiana and so far i cant seem to find a good mecanice and everyone I have taken it too has changed something on it that did not even needed to be changed. Can someone out there please help me out on this? ( please no rude answers) Thank you all

Something I should say, about a month and ahalf ago. I was on the highway when I made a turn into a mall and it just shut down on me and went dead. I replaced the fuel fues I think that is what its called. Its been known to just start losing power and then going dead. Like today when it went dead it started up fine and when I stop to get gas it wouldnt start up. But after I getting a jump ( keep in mind I put in a brand new battery and altertnator) it started up but then ran like it wasnt getting power. I do not think its the computer brain, cause if it was the computer brain, it would just go out. The starter is fine. Please I am asking for HELPPPPP. Anyone out there in the plymouth indiana are that can help me please do so.

Answer 1

First thing i feel that if the car starts but want stay running i would start looking more towards the computer of the car or the coil without doing a noid or spark test fuel pressure test and noid light test i couldn't promise anything it very well could be the something behind the timing cover in the timing

I keep telling everyone on here there's more parts replacers than mechanics out there! Thanks for the confirmation!
As for your question of an electrical short, they are usually in the dash area. But keep in mind, ANY direct short will kill the engine! So, they are tough to find and the best way to do it is approach those "wierd" things like the radio light and ABS light because they are all in the dash and as I previously mentioned, in 35 years I've been fixing GM products that's where I found 99% of them!
You can go back to the fuse panel with an ohm meter to find what circuit the short is in but you still have to trace it out!

Answer 3

Are you sure this is an electrical problem? Check the fuel pressure and if OK then check the ECU, by switching is temporally one that works. A good mechanic should be able to hook up his computer scanner to the OBD port to 'see' what is happening. Also once the engine is started check the exhaust as a plugged CAT may be causing this problem, by severely constricting the exhaust system. Good luck.
