1986 CHEVROLET

Guys I need some serious help here. I have an old 86' chevy S10. The truck ran fine. Not sure what is going on. I put new plugs and wires in it. Ran fine for two days. Then it stalled and would not start back up again. Makes and odd grinding sound when I try to start it. After the stall I put a new battery new distributor and a new rotor in it. I am looking to put a new O2 sensor in it if I can figure a good way to get to it. Checked all the connections everything is fine. The grinding sound seems like its coming from somewhere near the starter motor. The engine is turning over though. This is my plow truck cant afford to buy a new one or take it to the garage

Please need help! Any suggestion would be great.

Did it run fine before the new plugs and wires?
Odd grinding sound? Does it have oil?
New distributor--are you sure it's installed right? Is it getting spark? Fuel?
Grinding noise near starter-test the starter and check the flywheel teeth.
Just some suggestions.

Ran the same before and after plugs. Put new dist on after stall. Im pretty sure its on right b/c its shaped so it can only go on one way. Oil seems fine. Not sure how to test a starter. Spark is there. And the starter does turn the engine. Just not sure if its enoungh to start it. Noise started after the stall out. Thinking maybe I damaged it trying to restart it.

Sounds like you're part way there. At least it's cranking and you got spark.
Should check for fuel to the plugs.
The distributor is probably where part of your problem is at.
Did you mark the old one and match it with the new one or just drop the new one in?
If you did you need to pull it and turn the engine to Top Dead Center for #1 cylinder on compression stroke and align and make sure the rotor points to the #1 terminal on the distributor cap with the distributor installed.
Do that and if you're getting fuel it should start.
That noise probably is the starter. I'd fix the timing first and try to get it started and then deal with that.
Make sure your battery's fully charged trying to start it.
Good luck. Let me know your progress

Turned out that the module was bad. At one point the wire going from the module to the dist. Popped off. When I saw it I thought that was the problem. Plugged it back in and got nothing. Initially I thought that the module was the problem but wasnt sure how to test it. Sent the truck over to the mechanic and he tested it. Guess I should have gone with my gut! Still not sure how I could have spark though. Maybe it was inermitently bad?

Yeah, should've went with the gut--would have been cheaper that way.
Shoulda, coulda, woulda
And after all that typing about #1TDC. Blah blah blah blah blah blah blah. Was in the right ball park at least.
Must have been a weak or intermittent spark.
No more weird grinding noise?
Glad to hear you got it fixed. Thanks for letting me know.
