87 chevy s10 engine turns won't start, lights not on

Good Morning jamesmk, a fusible link is actually a significantly heavier fuse than normal, these are commonly mounted from the positive battery connector and give protection to the downline wiring circuits and items running on them.

It is common for circuits in the vehicle to be operated from different fusible links that have different ratings, some vehicles may have several different links usually all supported directly from the battery terminal.

The emergency hazard lights commonly are on a less likely problem circuit than the normal powered system for the engine and general electrical operating stuff.

So you will appreciate why the mentioned symptom gives the appearance of a fusible link problem.
These F/links need occasional inspection for corrosion and condition.

I just read your other post and it sounds like you may have a problem with one of your fusible links or its connections also.

By the way also ensure the negative lead from the battery has good electrical path to the engine and the chassis. This can also cause similar problems in some cases.

Cheers, qldit.

I have an 87 s10 2.8 4x4, replaced battery, alternator, fuel filter, battery posts. worked fine yesterday. I started just fine this morning, then it died after about 5 minutes. Now lights won't come on, dash lights not working, turn signals and emergency lights do. Fan turns on but when I press to full power it makes a noise and doesn't work. Engine turns over but won't start. I need emergency help if anyone is out there.

Thank you.

Hey Kgifford,
Make sure you have spark at the plugs, you could remove one of these placing it close to a "grounded source" then have someone watch it as you crank the motor to see if you have spark.
It does sound like a fuse able link witch on your truck would be located right before the starter, on the main power lines. They are odd shaped rubber pieces on the wire (1 inch in size generally) that goes to the starter, check to make sure you have power on both side of the link using a test light. Also may need someone to crank the motor while you check these.2.8 are a good motor had one with many miles on it, loved it!
If you have no spark at the plug then remove the coil wire again place it near a grounded source then crank it to see if it sparks, if this has no spark then it's probably the coil that is bad.
**** NOTE****
NEVER TOUCH THE WIRES WHILE CRANKING!!!!!!! Unless your hair needs to be curled :laugh:.
If the motor cranks then it's one of two things , no spark or fuel. If you can get a fuel pressure tester see if you have 60 pounds or more if not then the fuel pump is gone. Try pouring a little gas (two pop caps full) down the intake to see if she catches then you'll know for sure if it's got fuel.
Let us know what it was, hope we helped you
