Have you checked the EGR, and IAC? The IAC can cause all kinds of odd starting and idle problems if it is bad.

My info showed this for coolant temp sensor. Two wire connector, wire colors purple and yellow.

S10 PICKUP , NOT BLAZER S10- , NO ENGINE TOLD NO DRIVE LINE TOLD.! NO VIN TOLD. ENGINE RUNS FINE? DRIVES FINE AND ALL OTHER THINGS WORK THIS IS ALWAY SQUESTION 1 FOR ANY ELECTRIC FAILURE. 4l60E TRANSMISSION? OR STICK SHIFT, iT MATTERS TOO. THE 4L60 E HAS VSS VEH, SPEEDS SENSOR ON THE TAIL SHAFT OF THE BOX.. no speedo cables here. this year. the cluster has 1 fuse, Marked INST-lps if blown the much of the cluster dies. means insturment lamps(LPS) the question really is , all fuses good. and if automatic trans does the VSS go to the TCM (so it can shift right) then the TCM tells the ECU speed too. then it sense speed data to the cluster. sadly the scans of the old paper book , are blurry and 100 pages long, i refuse to read all of those for all engines there or transmissions not told. NO FUSE JUST FOR IT.!! 1992 IS THE SPEEDO ONLY DEAD? AND ALL OTHER CLUSTER THINGS WORK>? OR NOT. oil gauge, fuel ,voltage meter, and odom? ,eng. temp? ALL FUSES GOOD, IS FIRST. JUST CHECK THEM ALL NOT WORRY WHICH IS WHICH. SPEEDO DEAD, OR BOUNCES OR STUCK HIGH. WHAT? ODOMETER DEAD"MILES) DEAD? OR WHAT? ING fuse must be good , goes to cluster too. the book, deep looking shows DRAC vehicle speed sensor buffer;. here it is, and it drives the cluster directly so is sensor ,wiring or the buffer bad. the signals are very weak so the board here is a Ampifier it states vss to ecm, tcm and cluster. so if the ECM cans show the VSS dead we know the DRAC is bad or the sensor left hear is dead. the red circle below is cluster INPUT VSS. CHECK ALL FUSES. i CAN'T

Question edited for a bit more clarity. When you replaced the fuel pump did you disconnect the battery? When you reconnected the battery, did you reset the security system and engine immobilizer? https://www.google.com/search?q=1996+chevy+s10+reset+security+system Or hand it over to an auto-electrician. https://www.google.com/search?q=mobile+auto+electrician+near+me ..

Hi, Please first reach out to your local advanced autoparts or McMaster-carr and request that they email you the fusebox diagram. If they cannot do this, then you can request the same from Chevrolet by calling them at 1 (800) 222-1020. Thank you.

google "how to replace the heater core on a chevy s10 pickup" and it will come up with lots of video and text on how to do this

C1500>? there are no digital books then or PDF so only googing deep finds some,. person scanned it at home. or buy GM book used on ebay real 1994 here air is blower I think

your doing the tests wrong (best I can tell) most cars for sure USA. the pump only runs key on for 1 or 3 seconds,called the injector PRIMING state. (keyed on only not cranked) and then.... and for sure the same relay closes full time , cranking or running. so on dead engine all techs know this and crank at the same time measure the 2 power pins to the pump. in your case it fails. I bet but that is the only test here. next is the relay, most have 4 pins as yours does. . the PCM energizes the relay pump if you crank the starter I can only assume cranking works all good????? these rules in the PCM prevents crash and burn, like Ms Heche(RIP). did. crash ,engine stalls and pump goes off line and not a huge fire. from broken fuel lines, and is USA law too this. safety on some cars fuel relay goes off one if spark is lost and for sure injectors are shut down spark seen dead. all this is pure PCM logic. deep inside.. all this is covered in ASE classes to techs. how all this works it's home users (DIY guys that do no know this ) so here is my lil' hints. late. it does not work like say a swimming pool pump.sorry 2.2L engine. oops this 2.2 L puppy has oil pressure switch that kills the pump fast after a short run of he engine, saving it. all fuses must be good, top PCM too, f9/10 and check engine light good must glow key on or PCM is dead the ecu enables fuel pump relay first. then oil pressure good susains the fuel pump relay. so PCM F6 dark green/white wire is what energizes the FP relay coil. if pump is dead (voltage dead) to pump cranking , no longer than 10seonds(not overheating starter) and fall fuses are good. all as in ALL. F6 wire at ECU/PCM is check next or at FP relay. check all pins of FP relay for correct voltage cranked (dead engine STARTER Good) and be fully aware of all ways the PCU will shut down the FP relay not saying I know them all , it is Firmware logic in the PCM. better photo here. https://imgur.com/a/rB4j125

On a vehicle that age you probably have insulation on wires that have rubbed through somewhere and are shorting to ground. Look for where the wires go through the firewall to the ECM https://www.google.com/search?q=1994+Chevy+S10+4x4.+The+gauges+and+speedometer+keep+blowing ..

Distributors and the cap will only fit one way. Check out the videos in the link. https://www.google.com/search?q=Where+is+the+wire+located+to+put+distributor+in+neutral+to+set+timing+on+a+1997+Chevrolet+S-10 ..

maybe this article about starter relay can help you, you can refer to it or its related articles.https://www.apogeeweb.net/electron/starter-relay-vs-starter-solenoid.html

look for the clip at bottom of door or buy a replacement one

https://www.carmanual.org/chevrolet-owners-manuals/1995-chevrolet-s10-owners-manual-2093/ page 276 starts your fuses and relays and all connections are under the seat

Won't start how ? You put the key in the ignition an turn the key to start ,what happens ? Does the starter engage an spin the engine but doesn't start or it does nothing ? When you turn the key on do the lights in the instrument cluster light - check engine , ABS , battery , SRS - air bags , ? If you can't supply more details your best bet mite be to take it to a quailfied repair shop.

Hopefully the picture is correct, if not, my bad. under the hood, driver side firewall.
