Chevy Throttle body BEST CAST BULLET?

[ascast]

So today I start to plow snow with my new '94 Chevy Sierra and it just quits. I assume it needs gas so in goes a clean 5 gallons. Nothing but coughing 10 second run and then dead. I have taken out the air filter and TB unit. No **** did I find. When I hit the key it sprays gas all over the place ( TB removed). Could the injectors have plugged? Or suddenly a pressure drop in the pump so it too low?
What size cast boolits will fix this?
Any opinions welcome and thanks

[garym1a2]

If its getting fuel I would check the ignition system. This truck has a distributor with an external coil.

May I suggest a few well placed Lee C452-300-RF atop a full house load of H110 that outta just about fix it once and for all?

Go to the basics: Fire , fuel, compression....

All internal combustion engines need these three things to run. Put your TB back on and check your fire...spark from plug wire, then coil.

After that , check fuel pressure/delivery. These trucks are notorious for faulty pumps. Located in the tank. Have some one turn motor over and hit the underside of the tank with a rubber mallett. (A good heavy boot works if you dont have a rubber hammer.) If it runs, you need to replace the fuel pump in the tank.

Good luck!

Well, if the above doesn't fix it, remove the battery cables, reconnect, and try again. I did this with a Tahoe. It resets everything back to factory defaults, in my case, all was good with the world. (Including my wife, who was driving it at the time.) I don't know if your Chevy has all the computer controlled junk my Tahoe has.

[Mytmousemalibu]

Those TBI units are notorious for bad fuel pressure regulators. Could very well be a weak pump too as GM's of that era and later were bound to need a fuel pump at some point. If it is a pump, stay far away from Airtex brand pumps, absolute garbage.

If all else fails, a Lyman 525gr 12ga. "Pellet" slug will cure it real good!

[swheeler]

The best way to fix that problem is to trade it in on a FORD!:kidding:

[Geezer in NH]

Yep after all 95% of all Fords since 1990 are still on the road. The other 5% made it home.:kidding:

Try a good garage????

[runfiverun]

I'd check the electrical side of things.
I ain't had a chevy yet that didn't need some extra wires run around something here and there to make it work for another week.

probably the module.

[shaper]

Son n law had the same problem with his 1992. Found the distributor cap was toast. Put a new one on and it runs like a new truck. I have 3 Chevy trucks, 81 c-10 short bed step side, 89 Cheyenne, 89 Silverado. No matter the brand, all will have a problem in time.

[Mk42gunner]

My bet is fuel pressure is causing your problem. Get a test gage, either buy or rent at a parts store.

My cousin is a Chevy guy and I remember him complaining about his truck wouldn't run because the pressure was a whole one psi low from spec.

This is just a variation of "If you can't fix it with a hammer, you have an electrical problem."

Say, that's a helluva crimp on those, BTW.....

[Mica_Hiebert]

If it is spraying fuel like you said then it is a spark issue. Tbi chebys like the blow the h.e.i. Module in the distributor, looks like a little half moon with spade connectors on both ends.

[Lloyd Smale]

that old and a plow truck I sure it has some rust. Common problems up here with salt Is wireing. corroaded hot lead or ground that works sometimes and doesn't others. Grounds are the biggest culpred.

Not cast boolits but my vote goes to m1 garand with AP ammo.

A little thermite down the suck hole and you will have a nice backstop

THAT'S Funny !!

Reminds me of the old saying,
"Buy a Ford, buy the best - Ride a mile, walk the rest"

[Plate plinker]

Mass airflow sensor. It is between the TB and air filter box. Pull it out and clean it with electrical cleaner stuff. I think if you unhook it and the truck runs that is the simple test.

When ordering a new Chevy always get the heated tailgate option! It keeps your hands warm while pushing it.:Fire:

My 90 chev short box 4x4 had something similar happen 2 or 10 times, lets see control module 2, rotor 1, fuel pump 1, then 5 speed Gutrag 1, 4x4 shift module 1, rear diff 1, clutch 1, alternator 3, water pump 1, ac compressor 1, oil cooler line 1, door hinge 1, ignition switch 1. I bought it in 1995 with 85k on it. I bought a new 1981 GMC Sierra Grande that was about as bad. My bow tie days are over[smilie=1:

That's funny!

[popper]

Check resistance of the solenoids - else the module is **** - used to be ~ $400 for rebuilt. Don't use chlorinated cleaner on the MAS. Did you let the injectors thaw - water in gas? Only thing worse than those was the solenoid controlled carb.

[lancem]

OK it's a 94 so no MAS that was 96+. What do you mean you took the TB off? If you turn on the key and the injectors in the TB are spraying gas is it one or both? It is either the injectors are clogged and stuck open or the module in the distributor is bad and has them turned on all the time. I have had both happen but in my case when the module went bad the injectors didn't fire at all which is what I would believe to be the common failure for that module.

[leadman]

I think the op meant he removed the tbi and turned on the key and it sprayed fuel. Doesn't mean much as the pressure could still be low. Put it back together, check for spark, if ok then check for correct fuel pressure. In a pinch a set of old a/c gauges can be used, or an auto parts store may have the fuel pressure gauge for rent.
If you have spark then a bit of fuel in the tbi and see if it tries to start. Careful, do not start the whole truck on fire, unless this would "fix" your problem! LOL

Having worked on pretty much every car line made at various shops. Chevy TBI, its the ignition module, fuel pump, computer. And often time repeatedly replaced. The in tank fuel pumps were more of a maintenance item, 50k and it was borrowed time. Mercedes had the fuel pump under the car for a very long time, they lasted and lasted and lasted. Soon as they put em in the tank, we replaced them constantly. Mercedes even incorporated a removable plate so we didnt have to take the tank out we were fixing so many, vs a more reliable pump. The ignition module, it was the heat cycles sitting on top of the distributor that wiped em out, a bit of wire and a cooler location, like VW and they rarely need replacing. Computers seemed like an ongoing issue w US cars.

Funny, and I have never thought about it...but I have replaced the fuel pump on my Chevy's...but NEVER replaced one on any of my Ford's.

[ascast]

Chevy update- I pulled the plug and they were covered in black soot. Put in new plugs, and she fire up, rough, but running. I plow a couple passes and quit.
Dumping a little gas in the carb (TBI) opening. Lots of cranking and she'll fire, and sputter out. Pulled the new plugs and they are very wet. So what does that mean?
Where is the fuel pump on a Ford? I'm going after new plugs.

[Hogtamer]

Truck made in Georgia....go out in this weather? you gotta be kiddin me!

[Jniedbalski]

Besides the control module under the cap there is another electronic pice under that plate that goes bad. It's called the pick up coil. You have to take the distributer out to change it most likely it . My truck is a 94 suburban same problem

[Geezer in NH]

Needs a real mechanic is what it means.

[lancem]

Sooted up plugs means it running too rich, to much fuel, wet plugs mean way to much fuel.

[ascast]

It turns out that the auto-choke is controlled by the coolant temp coming off the block just before the pipe to the radiator. If it fails, the gas just dumps in.
Tossed one in off another junker and we're up and running. Plowed snow for about 1 1/2hr.

So, I probably could have cast up 5-6,000 boolits in the time I've spent on that truck.

[TXGunNut]

Yep, systematic electronic diagnoses aren't perfect but much better than virtual anecdotal ones. Too often one part replaced in error costs more than a simple professional diagnosis.
But, just to throw out my two cents worth, it's amazing how many odd issues are caused by something as simple as low battery voltage.

Must have used a shrink wrap to get a Band crimp like that? Dang! that's tight,

[bensonwe]

I have a 1995 Silverado. Had it since new. I've had to put two fuel pumps in. The way I check is rap on the bottom of gas tank with soft mallet while someone is cranking the engine. If it tries to start and possible runs for a 10 second count its the fuel pump. Very easy to change just takes time. Remove fuel. Four bolts holding two straps that support tank. One clamp for fill neck. Two wire connectors accessible after tank is lowered. Remove ring. Remove pump/sending unit assembly. If sending unit was working properly just replace pump. Over 800 dollars for garage to do. Under 100 for me. Look in rockauto for parts. Hope this helps.

[44man]

Most likely, had to change many. But those TB things are crazy anyway and there is a unit at the top that can fail. Too much gas or not enough.
Now I could not start my Chevy once with new plugs. Store did not have AC plugs so I put Auto lights in. NOT! Champions fail too and the radio will go nuts.
There was a gadget that told the puter the engine is turning so turn on the gas. S10 was a *** when the thing fell off the firewall and was on the bell housing to corrode. $5 fix. Failed again and I found a bad diode in the puter. 10 cent fix.
If I remember the thing read oil pressure to turn gas on and the corroded sensor put too much resistance on the diode.
Spark plug wires-- opened the hood at night and it looked like Christmas.
I went to Toyota.
I had Fords long ago and fix or repair daily was true. I don't know how many times I had the Holly carb apart. Next day radio quit, then turn signals, then horn, dash lights. I don't think a day went by that I got home from work and did not have to fix something. Chevy not a lot better. Chrysler products were born in dumpsters. Don't even say JEEP around me!

[starmac]

Sounds like the temp sensor was the culprit. I had the same problem on a 95 I had, it would flood out going down the highway and kill the engine.

[quail4jake]

Yeh, plug into the 'pooter for a quick look otherwise it's a guessing game. My '88 K3500 had TBI trouble and I learned that they will hose you with gasoline if things are out of wack as soon as you turn the key! My two fords are no better. Usually a sensor issue, replace and drive on. Good luck. Of course if that doesn't work 10 lb of molten range scrap poured down the TBI will bring a definitive end to it all!

[44man]

.500 Jrh will cure it all!
