My 86 chev.pk-up. 49k mi. 350 5.ol-6 lep 4 barrel. Parked outside my garage won't start. No previous clues. I put some "quick start" in carb, but eng. Ran only seconds.what is likely & unlikely wrong? Please suggest some steps to take. Tk's.

Check fuel pressure. If it runs when you spray starter fluid in carb it means it is not getting fuel. Clogged fuel filter or fuel pump.

my 86 silverado pk.up.is getting fuel to carb. now what to do?still won't start.

If it is getting fuel to carb, it should start. If you pump the pedal 5 or 6 times will it run for a few seconds? Pour some gas down the carb, will it run for a few seconds? Can you see fuel squirt when you look down carb and pull on linkage at the same time? You may need to rebuild the carb, it is hard to tell without actually seeing it.

still won't start. do i buy a carb. kit? any details i need to know? tk's for all your help.

If you have no experience rebuilding carbs, it might be better to find a carb rebuilding shop. They are there but hard to find. You didn't say if you saw gas squirting down throat of carb when pulling on linkage.

i have a 2001 silverado that wont start eather. i have fuel spark and good compression hooked up my obd 2 and it gave me p1638 which is my alternator but shouldnt it start from a boost any way? it will turn over all day but no sign of life at all.

oldchevy

Back to checking the fuel pressure. Having fuel is not enough if the pressure is too low.
