I looked through all of the past topics and found similar problems but none that could help so here goes:
Yesterday my alternator went out. I replaced it twice (I seemed to be making a habit of this twice thing-I had to do a heater core twice about 2 weeks ago) because the first replacement was only putting out about 11.5 volts. Not a problem-alternator was a piece of cake. The problem began because I had ran the battery down and had to hook a charger up to it (had battery checked to make sure it was good). I left the bat in the car but disconnected the termnals for charging. After getting the second alternator in and while hooking the battery back up, I noticed one of the fused links connected to a red wire going to the battery (that had apparently been repaired before I bought it) had seperated at the connector. There was not enough wire left to repair it so I went to the dealer and got a new connector and reconstucted this part of the wiring. Basically it consisted of two seperate circuits. The original had a red wire going straight to the battery terminal and one going to a single wire connector to a fusible link going back to the firewall and to the fuel pump relay (I think). Both of these wires were connected by a black covered butt connector and made a joint for two seperate fusible links that went down by the exhaust mainifold area and to a two-wire GM connector. I reconstucted this the best I could-using a new male end two wire connector, about 6 inches of fusible link and the old single wire connnector on the other end. I can see no way that this should not be a suitable replacement for the old wiring.
However, now I can not get my vette to start. I believe I have narrowed it down to being a fuel flow problem but can't figure out why. I have replaced the fuel pump relay-but I don't think that is the problem since when I checked I don't have power going to the relay plug (key on or off). I also don't hear the fuel pump start up when I turn the key on but I know it is good because I ran a hot wire from the bat to the ALCL under the dash and the fuel pump runs fine. Don't have hardware right now to check fuel pressure but have help and guages coming this weekend. The car does fire momentarily when I spray starter fluid in to the butterflies.
FYI the car ran fine yesterday morning when I was test driving the first alternator and the no start condition did not occur until I tried to test the second aternator and after the wiring repair.
Also one other thing to mention is that my "Service Engine" light does not come on (it worked a couple of weeks ago) I found this out when I looked for trouble codes. Before you ask, yes I pulled the dash apart and checked the bulb and it was fine.
Also took the time to check the usual stuff, coil. rotor, ICM.
What I am suspecting is that there is another sensor that I damaged somehow electrically when I was working on the alternator, charging the battery, are fixing the wiring, that may also be causing the check engine light to malfunction. Either that or I screwed up the ECM in the process.
Any ideas or words of wisdom would be greatly appreciated.
