92 s10 wont start Sign In

Inherited a 1992 S10 p/u from Dad. (On purpose i think. My 2 bros do chevys. His only daughter, a ford fan. Sorry)
4.3L V6 160,000 mi.

Just FYI...It had resided in Fla.for the last 15 yrs. & had 20-30 "Grandpa" miles put on it sevral times a week. Brought it to Atlanta in Oct. & have
put 10k commuter miles since. Salt air got to the paint a little,but otherwise all is original everthing.

Friday my son left work,stopped at a store,got back in truck & NOTHING. It turns over,but wont stay running. Not really any warning signs,though
it had not been running quite up to par. We knew it was about tune-up time.

Thinking fuel related 1st- put a new filter on.(Crap that came out of old 1 was embarrassing. Could have even been the original filter.) Same problem.
Towed it home. Next,tune-up. New plugs,wires,distributor cap&rotary button. Same problem.
Next,sensor time...Replaced the TPS,IAC & 1 other that i cant remember. Sorry,tired,frustrated&son is asleep. Same problem.
So,now.....put on new distibutor. We just knew that would be it. Wrong.
So, here i am. Any thoughts,ideas or just a slap that says "what about this,dumbass?" because it may be something minute that we just didnt do,
will be greatly appreciated.

I didn't see a fuel pressure check on your list and is a must to know especially with finding a dirty fuel filter and the troubles too.

Might need a whole tank and pump new and or clean tank but bet it's not way too expensive for new?

have to find a gauge to borrow. And, new tank probably $100.00. Think my son was set on
getting new fuel pump tomorrow,but MOM is gonna check pressure 1st,at your suggestion.
Thanks for your quick reply. Will update for sure.

Checking the fuel pressure is definitely what needs to be done but it may be a bit difficult to adapt a gauge on that vehicle. They make an adapter that substitutes for the fuel filter that makes it easier.

You can try spraying some carb cleaner or starting fluid into the intake to see if it starts right up on that to further indicate a fuel issue.


We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

I forget but pressure may not have a port but rather you put an in-line tester. Watch with just key on run then off and how it holds too for how long.

Check on new tank and any necessary hardware, fuel neck may also be involved but the very best cleaning isn't either very easy or effective IMO - I'd personally go new and hate to say new OE pump assembly for GMs especially - pay the extra.

Pumps fail by being fuel starved from a sock on pick up sock inside (do use new again) AND from running low on fuel or worse, out of fuel never mind how old it is.

Fuel injection can also be an issue so testing and checking can and will save waste if you son isn't capable because of tools and equipment get it diagnosed and decide to send some work out or DIY thru son if up to it.

Side note: You said you didn't care for GMs vs some other maker. It's always something with any really. If this is a fairly low mile southern rust free 4X4 version hit me with a PM if you are selling it! I'm serious - I like the drivetrain of the 4X4s on these at their size and stuff that old is usually all rusted out up North where I am or many beat to death also - this sounds like neither has happened! Smile - I mean it too - for a PM (private message) click on my name and look for the option if you wish to do so,
