Reason why i ask, my 1988 Chevy Silverado TBI 305 5.0 V8 "SOMETIMES" hesitates and or will shut off- after a stop or even while at freeway speeds. it STARTS right back up- without a problem.
I just spent $127.53 For a OBD1 diagnosis- Nothing found everthing is in order-PER Mechanic...But found a "clogged Fuel Filter". trouble seemed fixed until the next morning...
If i let off the accelerator, and "pump" it a couple times it seems to clear right up and drive strong.
I will get a second OBD 1 Diagnosis at a different Repair shop and see if he can find my Truck trouble.
If anyone out here has an idea or a opinion please tell me everthing i might check or do!
Complete tune-up 4 months ago, never had any trouble, NO leaks, This trouble just started last week...
Cat Converter has a broken weld/leak- nothing further "enitire Truck"
Thanks folks,

This could be alot of things. But with a truck as old as yours, it could be corrosion in the wiring. If the wires going to the fuel pump are frayed, or it's grounding out it could cause it to shut off intermittly.
Or it could be a bad Coil. The problem with these kinds of issues is it requires alot of checking and searching. Sometimes you get lucky with a good guess. But it's going to require some work. You can save some money by doing it yourself. If you can pull your fuel pump off, check the wires and even check the flow by running a tube into a bucket of mineral spirits.
To check the coil, pull it off and take it to your local auto parts store, they should have a multi-meter and help you test it.
You could also ask the guys at the autoparts store about what else could cause this problem. Like I said there could be alot of causes, some related just to your truck. Good luck!

I own a 1991 Caprice with a 5.0 TBI and my car has the same problem as yours does! Don't make the same mistake I did by replacing $2000 worth of parts to try to fix it! I replaced the coil,ignition module, the entire distributer,all the wiring harnesses, the TPS,MAP sensors, and the main computer with all new spark plugs and plug wires and it still is cutting out the same way! I have come to the conclusion that the problem must be the fuel pump! So this weekend I will replace my fuel pump God knows I hope this will repair my problem!!!. The good thing is that I have replaced so many parts that Everything should last for years and years! and I know have a whole box of extra parts in the trunk so if I break down I should be ready to do the repair on the spot!!!!

Sounds like a fuel filter again. You must have gotten some bad gas or somebody tried to mess with you. I think this time I would pull the tank and pour all the gas out and start fresh. Somebody already mentioned the crank sensor. That could be your next move if the filter doesn't correct the problem.

you'll be able to think of the torture difficulty is unimportant, yet we are speaking approximately no longer something below our id as a rustic. And definite - whether it particularly is got here upon that Pelosi and different Democrats knew approximately and authorized torture, they should additionally be prosecuted to the entire quantity of the regulation. As Newt Gingrich HIMSELF reported after his assembly with the chinese language president in ‘ninety seven: "...there is not any place for abuse in what might desire to be seen the kin of guy. there is not any place for torture and arbitrary detention. there is not any place for compelled confessions. there is not any place for intolerance of dissent. I defined to President Jiang how the roots of yank rule of regulation return better than 700 years, to the signing of the Magna Carta. the commencing place of yank values, for this reason, isn't a passing priority or a non everlasting vogue."

These older vehicles sometimes had intermittant fuel pump operation when they would be going bad and the connector in the tank where the fuel pump plugs in are common for bad connections.
