1988 s10 blazer 2.8 4x4 automatic. I just upgraded to a 3.4 v6, all machine work done, engine has all new internals. I have spark, i have fuel, but it will not start. I have checked the timing over and over, it is fine. I need a checklist or something to look for, all sensors seem to be hooked up and it still wont fire.
View 6 RepliesAnyway I have a 88 s10 blazer that will not start, I've replaced fuel pump, filter, charcoal canister, also the rotor, cap, plug wires, module, pick up coil and ignition coil. Before I changed the pickup, it would start till it warmed up then die, wouldn't start again unless I gave it gas, if I held it steady the rpm would fluctuate but stay running till I let go of the throttle. Now that I've replaced the pickup coil it turns over, I do have spark but it will not start. I bought a code reader all I'm getting is code 12 which is no distributor signal to ecm. Like I said I e replaced both the module and pick up coil.
View 2 Replies1986 S10 blazer automatic transmission won't go into reverse OR neutral! It goes fwd in both reverse and neutral. It goes into park just fine. The fluid is full and not burnt. It will drive forward when in reverse and in neutral. I turned the engine off and checked neutral, it was not in gear but tried to go forward as soon as I started the engine. I have never seen this!
View 11 RepliesI've changed the fuel pump, spider, fuel regulator and checked all the relays and fuses. The only way this truck will start is to prime the engine with a shot of gas and then it will start and run great. Shut it off and NO Start.

View 2 RepliesHer vehicle is a 2003 Chevrolet Blazer, 4 door. It has a brand new battery.
She drove it to the store and came back home and shut it off. Within 5 minutes she tried to start it back up to move it and it won't start. When she turns the key, all dashlights come on, all gauges work and the engine is turning but won't start.
When the key is turned, I do not hear the fuel pump. But I've been told that in some vehicles you don't.
We removed the cover under the hood and took out the "plug" that said fuel pump (it was grey and had 4 prongs on it that plugged in) and switched it with another "plug" with the same numbers and it still does the same thing.
Hubby took of the black cover (think it was the breather but not sure correct name) and sprayed a little starting fluid and the Blazer started for a few seconds and would continue this until it burnt up the fluid. He looked down in this when I was trying to start it and he said that he couldn't see any gas being shot in it.
Could it be anything else besides the fuel pump?? Where is the fuel pump relay switch located and how can we tell if it is bad? I have no problem buying a fuel pump for my mom but I would like to know that it is going to fix the problem.
I have an 02 Blazer w/ 110K miles. It's the 4.3L with 4WD. When I start it in the morning it usually has a low pulsing whirring sound for up to 30 seconds. It then goes away until the car is parked for a long time again, say overnight. It's a low volume sound, a lot like the sound of off road tires running down the highway. This has been going on for several months now.
All systems work fine. The alternator is new, the water pump has about 29K on it, and the top idler pulley has been replaced. Turning the A/C on or off makes no difference. The sound is loudest when you stand in front of the passenger side headlight which made me suspect and swap the alternator.
Could it be the belt? It was replaced with the WP and the ribs are not smooth inside. They are notched. I assume that's to improve the flexibility of the belt. If I take it to a shop they'll get 30 seconds each morning to diagnose it.
I have a 1998 chevy blazer and I cant get it to start. I removed the starter and turned the key and can see the starter popping out and spinning, but when I put it back into the flywheel all I get is clicking noise(like if the battery is dead) I had it on jumper cables so I don't think its the battery?
View 12 RepliesI been having occasional problems starting my 1988 honda accord. It also sometimes dies when im stopped for too long. The problem has gotten worse more recently. The engine will rev and struggle to start. After it dies out i often have to let it sit a while before im able to start it. As i am trying to start it im smelling gasoline.
I thought for sure it was the fuel pump so i had it replaced and is still giving me problems. Today i had to give up and come back to it later. It is fuel injected... What the problem might be?
I just replaced the auto transmission in my 1988 accord and upon first restart the car will not idle. I has been sitting for about 6 months while I replaced the trans, but was a daily driver prior to that. The car initially starts fine when cold, but shortly after startup starts running very rich and dies. Restart after this requires the throttle pedal to be held down. Engine will start after some cranking - but will not run under 2500 RPM and is obviously very rich. I've rebuild carbs before so I'm thinking about picking up a rebuild kit - just wondering if there could be other parts of the fuel control system that might be at fault.

When I start the truck, it idles rough, like it's idling too low, and even feels like it's missing during idle. Sometimes when I put it in gear (reverse or drive), it shuts off. No codes are being thrown. It has no problems driving around town or on the highway. It's just that initial start and idle.
I've checked all the following with a shop manual:
Ignition Control Mod.- Orig and 2nd one from junk yard. Both tested good at store. Even the testing in the shop manual with an ohm meter and battery tested good.
Ignition coil- tested good using shop manual testing
TPS- Scan shows .2-.7 at idle.
Plugs, wires, cap, and rotor are good.
Vacuum is good.
Haven't checked IAC, EGR
I recently moved cross country, and about halfway through, I broke down. Engine would turn over, fuel relay would click, injectors would work, but no fuel. Pulled it in to a truck shop, and after all my testing and theirs, we determined it was the fuel pump. After they had to fix a pinched hose, it ran. I made it to Texas. I didn't have the idle issues prior to the trip. Just had the tranny rebuilt and everything was great.
I thought, at first, the ignition control mod was the problem because it got a bit warm pulling the trailer, and I know those things don't like too much heat. No dice. So, what controls idle at Park and in gear but at idle? EGR, IAC?
I did a WinALDL scan. IAC at Park/Idle ranges from 18-55. The engine never runs in Open Loop. I would say the engine runs mostly rich according to the scan. I've attached a manageable version of the WinALDL data.
Also, I need to check the thermostat or temp sensor. Scan reads the engine never getting higher than 180.
So my 92 blazer won't start now I put an new alternator in and it won't kick over it want to start but wont..
View 3 RepliesIt turns over but wont start, i have changed the fuel pump, fuel filter, injectors, and i also put new connectors for the injector, and new plugs. But still will not start?
View 8 Replies88 s10 2wd 2.5 litre will not run with the f terminal of the alternator connected. Had alternator tested showed good but needle jumped around some, so went ahead and bought a reman. Put it on same issue. No codes. Unplug the f terminal vehicle will run. This is circuit 39goes to ign/gauge fuse 20A, which ties into the instrument cluster so i unplug the cluster no change.same fuse and circuit 39 go to ses lamp which should have been eliminated as a possible cause by unplugging the ipc. Other places circuit 39 goes is ac cutout relay, shift lamp, vss buffer.
View 3 RepliesFor about two weeks, my Blazer would crank but not start on the first turn of the key. After a couple of tries it would start and as long as the engine was not off for more than a few hours, it would start again with no problem. While driving however, the engine would periodically "hitch" like it was missing a spark, or not getting any gas. As of last weekend, the engine will not catch at all, and a light on the dash shows "low fuel" even though the tank is almost full.
Spoke to a mechanic who (without looking at it) diagnosed a fuel pump problem at a cost of around $1,000. Is there any other problem which may cause this issue? I have very limited mechanical ability, and cannot pull the spark plugs to test them, as they seem to be buried in the lower half of the engine block.
When I turn the key over to start the vehicle, the clock resets to 1:00, the back latch clicks and the car kind of makes a grinding sound but not like a churn as if it wanted to start. I don't know if it is just a dying battery or if it would be something else but my car will not start at all.
View 1 RepliesWent to start the truck, turned the key - dash lit up, fuel pump primed, turned the key all the way and nothing. Truck did not even try to turn over, headlights did not dim, no starter, no crank.
I checked/tested the following:
-Battery and terminal connections - good fully charged 12.3v
-Ran battery charger on slow charge 10-15 min (quick) to full 13v
-Wiring to starter - good
-Relay box under hood - has power
-Starter relay - has wiring diagram on it - tested good.
-Every ignition related fuse in the relay box - all good
-Every ignition fuse in the driver's side dash fuse box - good
-I wiggled the ignition switch while turning every possible way - no crank
-I ran the gearshift lever through all the gears, tried to start it in neutral - no crank
-Rolled the truck a little, put in park - no crank
For some reason I decided to double check the # 24 RDO IGN fuse - it was fine. With the fuse still out I tried to start the truck and it STARTED!
I turned the truck off, replaced the fuse and the truck started again and, so far, ever since. I do not think the # 24 fuse had anything to do with it; I just got lucky.
Why will the 96 Blazer not start in the rain? Replaced almost all electric components from key cylinder to plugs. It is grounded somewhere when wet.
View 3 Repliesmy 97 chevy blazer has a lot of cranking first start in the day. I changed the rotor and distributor cap but I don't smell any fuel then all fo asudden it will start. I am wondering is it a fuel relay problem, a fuel filter, or some sort of sensor. when it does start it is very smooth running no shaking or hesitation full of power for the rest of the day starts and stops erands . is it worth buying a plug in code gadget and will this problem show up as a code.

View 1 Replies3 months ago I bought a beautiful dark-blue 1988 Volvo 240, manual transmission. This is my first Volvo and I'm already hooked! It's the car that's going to teach me to work on cars because for the most part it's beautifully simple. I bought a repair manual to be prepared, and have now encountered my first real issue.
For several months, even in the rain, it would start and run beautifully. Now when it sits in the rain overnight it will not start the following morning, or until the weather subsides. Once it has a few hours to "dry out" after the rain and humidity stops it starts beautifully. In the wet weather it wants to start, the starter goes and goes and at points it sounds like it almost catches, though ultimately won't. I imagine moisture is getting in somewhere and preventing spark at some point in the ignition system, but, like I mentioned, I'm new to this. Where to begin; what I should replace to begin troubleshooting this?
In a separate issue I can't get fuses for the rear tail/brake lights to keep from blowing when I replace them.
