Check the ignition switch in the start position and see if you still have 12 volts.

1st and 2nd shift solenoids has sediment causing them to stick.or you got damage leaking seals. it might help if you put a little transmedic in transmission dont over fill. if your valve body full of sediment it causing valve in valve body to stick.this might help still might have to go in transmission.

yes can be done but will need some mods and programming ------and an s-10 trans tunnel will need mods --------this is a full size but shows some of whats needed for swap also check the s-10 forums for better sources on mods ------https://www.motortrend.com/how-to/129-1004-1977-chevy-4l60e-to-4l80e-transmission-swap/ -----https://www.motortrend.com/how-to/1307-4l80e-transmission-swap/-

another HUNT game, oh joy. No actual problem goal or job told,just a blind hunt and no model told, I do 1 hunt per day, you win. 2500 is not car, there are 4 chevys with that name, avalanche, express,silverado and surburbain what country>? 8.1L not that is huge. and is my only good clue. not express. all modern cars the TCM moved in to the PCM long ago, 1995 to 97 approx I will guess (why must I?) the 8.1 Avalanche. USA spec car. The Vortec 8100 L18 4L80 transmission now I will read the SM , to you, service manual on guess model truck the Manual SM tells this. Remove TCM cover from the fan shroud.step 7 (AND ERROR) confirmed 3 way above and is sold and schematics.show it not part of PCM, the transmission 4L80 wires to the PCM<> there is no seperate TCM. ALL pcm LOCATORS 8.1 SHOW Remove TCM cover from the fan shroud HUNT ENDS AT PCM THERE IS NO TCM IT IS INSIDE THE PCM. YES EOM HUGE TRUCKS WITH ODD TRANSMISSIONS HAVE ITS OWN TCM ,LIKE CAT ENGINE/TRANS COMBOS OR ODD DIESELS. NOT THI ONE.

PICKUP not VAN sold new 6 engines, then, 5.0L yours. when did it last run good, last week/month/year /???????? well in shop we'd check all fuses.. 1995 is long in tooth for ECU problems bad caps he ECU runs EFI and spark both ( a huge job) runs ,stalls and not restart. what you failed to I real testing and is not the starter at all. first (besides good engine) is spark if will not start, cranked spark is first unless you learned how to do he ECU CEL blink codes.(more later) I will not stop and see what is there in your shop manual (service) 5.0L v8 gas, engine, this the horrible old TBI system? 1 injector>? or is this the MPI , 8 injector engine, has distributor spark and must be timed correctly to work the CMP is in the dirtributor, the CKP is on the crankshaft. I test for spark first using both ways a test spark plug, gaped right, (new plug not old) and if spark is good great. if old plug is fouled;, carbon, oil soaked or soaking in raw fuel the fuel seen now is flooding, I then use a timing lite (yes even works cranking dead engines) and make sure static time is correct the DIZZY. if not it must be set correctly now. per the manual on car. I use the light to make sure al spark wires spark(mag pickup lamp) if not the distributor or the CKP sensor is dead. if all that seems ok out comes my trusty Instant start spray can. Air cleaner off, spray fuel here, 3 second blast , crank, and repeat until it runs 3 seconds to burn up you fuel sprayed. see? the engine is not dead, now, or IS deaD. IF FLOODING SEEN, crank with foot throttle depressed WOT and the trick cuts off the injector and the flood is cleared even starting an old engine like this with 5% throttle can hide a bad IAC air valve and allow it to start and the a active right foot to keep his beast running. but spark is first it must be good x8 and battery fully charged. this 5.0L is a TBI injected engine, 1/2 injectors not 8 with MPI some have a starting only injector then the signal; main to run theTBI is old and its pressure regulator can be bad./ one trick I use (means tactics) Is that I kill the fuel pump fuse or its relay pulled. this hides the bad TBI fully and now test fuel works all I want showing me it is just bad spark or bad fueling just doing that. the TBI can fail 3 ways, dead, way to lean or way to rich the latter is flooding and WOT cranking can clear floods. the goals ARE TO FIND?.

1. bad engine
2. bad spark
3. bad fueling

OR CATS MELTED, OR EGR STUCK WIDE OPEN BUT THOSE TO 2 THINGS MAKE THE ENGINE BAD. SO IS THAT.#! TBI CAN BE A BIG PAIN NOW THE FLASH CODES, EVER LEARN THAT/ THIS PRE 1996 CAR USA HAS OLD CHEVY OBD1 DIAGNOSTICS most folks never heard of it now but gee it is in the manual for sure. fl\ash codes (blinks) code 13 to 55 or more with A/t box. steps to do this, key off find ALDL connector (DLC modern named ) data link conn. see my photos. (books says under DASH) some near column The diagnostic trouble codes can be read by grounding test terminal B. The terminal is most easily grounded by connecting it to terminal A (internal ECM ground). jumper B to A THEN KEY ON AND CRANK THE ENGINE (BATTERY ALWAYS CHARGED FULLY BY THE TECH) AND CRANK FOR 10SECONDS, NO MORE THE RELEASE THE KEY (NOT OFF) SEE THE LAMP BLINK OUT FAILURES CODES.AT CEL CLUSTER LAMP, THE CHECK ENGINE LIGHT BLICKS AND THE LAMP MUST BE GOOD. (many are removed by evil sellers) quote flash Code 12. The code will display as one flash, a pause and two flashes. Code 12 is not a fault code. It is used as a system acknowledgment or handshake code; its presence indicates that the ECM can communicate as requested. Code 12 is used to begin every diagnostic sequence. Some vehicles also use Code 12 after all diagnostic codes have been sent. then other blink codes are next if stored or are live errors. 2 kinds live and stored, both matter to any tech. after Code 12 has been transmitted 3 times, the fault codes, if any, will each be transmitted 3 times. The codes are stored and transmitted in numeric order from lowest to highest. sorry for long post but 1995 cars are super hard to diagnose. even bad CAPS in the ECU are common now, and show stoppers. CODE 42 OR 43 IS BAD SPARK , I'D NEVER Forget to ask the PCM what errors there are, ever, ask it and win, also the lack of errors has meaning too. full stop this is what I'd do the first hour.

If you lookn the owers manual, all fuses are explained both position and value.

What kind of vehicle & engine size would be helpful?

You can try calling your local Chevy dealership (parts or service dept); buy a service/repair manual book or e-download, or join a Chevy truck online forum; engine size detail may be helpful.

STICK A PORTABLE HEATER UNDER THE HOOD CLOSE AND LET IT RUN ABOUT AN HOUR. bETTER IF YOU THROW A BLANKET OVER THE HOOD. tHIS SHOULD DEFROST ALL THE SYSTEMS.. yOU STILL HAVE ice SOMEWHERE. Mike sorry about caps.

If I understand your query right. Your truck keeps dying. 1. Might need a tune-up (plugs and gap adjust to spec.), plugs wires, fuel filter, cap, rotor. air filter) 2. I suspect the fuel filter-----or high voltage to ground (like spark to ground) For charging system 1. Battery test (Voltage reading) 2. Take the CCA (Cold Cranking Amps) divide by 2 example: 600cca / 2 = 300 3. With a carbon pipe tester load 300amps for 15 seconds and read the voltage drop. Should not go under 9.5volts if not the battery won't pass the test. 4. The alternator has to be tested for "alternator max.output" Make sure you have good terminals connection +and - of the battery before doing any test. Hope it helps.

Which engine ?

There are a few conditions that will not set a code. For example, stumbles are often caused by ignition coil problems. If the problem persists at a certain RPM, could be an O2 sensor problem in closed loop operation not lasting long enough to set a code, or a fuel regulator or injector problem. I would get a good code reader and check readings from all sensors in the circuit (including misfires) to see if you can pin down the problem.

you need a new blower under the dash most likely especially if you cannot hear the fan working when no air comes out. if the fan still sounds like it working even with the engine off but ignition on as a test but still no air it could be a heat flap control not moving to open and let air through into the cabin check and see which it is then get back to us with more info and we can better help you

Hooking up a scan tool that can view engine sensor data parameters would be the best way to diagnose . Where are the fuel trims (short & long term ) Adding or taking away fuel , are the O2 sensors switching normally , what is the fuel pressure & flow , MAF sensor data ? Without testing we'd only be guessing ,a lot of thing's could cause your problem . Your best bet , take your vehicle to a qualified repair shop. 069 Emission Tests Misfire Scan Data 064 Emission Tests Scan Data Pre Check How to test fuel pressure injector pulse and spark with basic tools Honda

Always start back at the beginning. Remove the master cylinder and bleed it before fitting. Then you can bleed the hub furtherest away from the master cylinder, working your way towards the closest. Also make sure all the pistons/wheel cylinders are pushed all the way home first.
