1997 chevy silverado 3500 with 454 engine won't start. New battery, new fuel filter, spark plugs good, fuel pump is okay. It turns over fine, but it just won't start. When it does start, it runs fine, but the problem is getting it started.

    I have a 1997 3500 pickup that will not start, We have replaced everything in the engine compartment that has to do with the engine running but we still have an erratic spark that just randomly fires which ever plugwire it wants to. We have a code reader testing the codes after every crank but it doesn't show anything different, it comes up occasionally with a random cylinder missfire but the thing should say random cylinder fire because it does not fire enough to run. We have replaced all the sensors, everything in the distributor, new plugs and wires, checked every wire and connector in the engine compartment, had the ecm tested by a hi performance programming station but all they could tell us was that all the information they fed to it it took which to them meant that it was working, does that mean that it's good and that it should run, they say yes but it still fires

    erratic and does not start.

    Any help you can give us we would appreciate. Thanks.

    My distributor is new We replaced everything else as well. I still am not getting any fire to the plugs. However when you crank it over it sounds as if it is trying to start. I believe the problem started with the previous owner It backfired and sheared the pin on the distributor gear. he replaced it and could not get it to start. I bought it and tinkered and got it started (don'[t know what I did) then about a week later it died took it to dealer they replaced coil it ran for about a month then died again. replaced everything cam shaft sensor. crankshaft sensor. coil, ignition module.still nothing.

We found the problem by taking the truck to the dealership, after spending $550.00 on parts and having everything we could remove tested or we purchased them new and replaced them. We spent two weeks on it and took it to Chevrolet but it took them three days after all we had done, the problem turned out to be the gear on the distributor, sure we replaced every part in it but because we could not get the distributor out with the intake on it we had not even considered the gear, thanks for your assistance and maybe we'll try you again next time....Thanks again.

Thanks alot for the info listed here, I had the same problem Engine turns but won't start and first bought a crank shaft sensor $75 and that wasn't the problem, next I bought a new distrubutor $120 and that was it !!!! My truck was fixed, Its a 1997 chevy silverado w/249,000 miles and is still going strong now, Thank you guys for your input.
The problem with my chevy distributor is after wear and tear it seperates at the gear at the bottom of the shaft approx 1/4 inch or so and causes it the jump and causes misfire of timing and my new distrubtor does not have that gap and after replacing it started right up. Thanks

Why won't 89 Chevy Silverado 1500 5.7 STILL not start. New battery,coil,spark plugs,wires,inline filter,distributor,cap,rotor,fuel pump,starter relay.


What's missing ? Fuel ,spark , compression ? How many miles on the vehicle ? Does it have spark , pull a plug wire while cranking an hold it near a good ground . Put a fuel pressure gauge on the vehicle , is there fuel pressure ? Do a compression test , 150 psi . engine mechanical problem . timing chain .

My 89 Chevy Suburban Silverado STILL won't start! New coil, spark plugs, rotor, cap, relay,battery,inline fuel filter, fuel pump,solenoid.


Have you checked for spark at the plugs ? Spray some carb cleaner into the throttle body and see if it attempts to run as this can show a fuel problem .

My Mitsubushi Space Star Car won't Start. What can I try?


spark plugs are deep in the head yet you should get all the the old fuel out first, stale fuel wont ignite and will also clogg fuel filter. you need a mix of atleast 70% new fuel even then its not good for the injecters. If its a manual gearbox a tow start is a quick fix although no go for auto's. cant be much wrong if car was fine when parked, plugs-fuel-filter and possibly fuel pump for sure. If that doesnt fix take plug out put in lead and crank engine to be sure you have spark even just put any plug you know works in lead leaving your plugs in engine just to check for spark y turning over engine looking for spark on plug good spark will be blue but any spark is good.

Hello. My 1997 Chevy Tahoe refuses to start. The problems began with a bad fuel pump. I changed. It worked. The fuel pump died again. I changed it again and it has been working. I parked it for two weeks....


Now you have a good battery & a starter that turns over the motor

Have you cycled the key on & off with a fuel pressure gauge on the
fuel rail?

Do you have a fuel filter that isn't over 3 or 4 years old?

Have you checked for spark while cranking ? Use an old plug on the wires,
if you have ignition wires,don't ground the wire without resistance

If you removed the ducting & MAF Sensor it won't start

Tell us what you checked & exactly how that was done.

1997 chevy blazer 4.3L cold hard start have to add gas to carb to start hot start is fine changed fuel filter and battery new battery it will eventually start but runs down battery.


There may be a problem with the fuel pump itself or the truck may need a basic tune-up. Those would be the first two things to check. Pull a spark plug and see how it looks. If it is in really bad shape, it won't be able to fire properly and this will lead to hard starting. A set of plugs and plug wires can really wake up an older engine. The second thing to check if those are ok would be the fuel pump itself. It may be weak and take longer to build proper fuel pressure. This will have to be checked by a mechanic. The fuel pressure is very high and there are special tools that will be needed.

1997 chevy silverado 1500 350 vortech, new fule pump not working


before you drop tank again, check fuses & relay.then disconnect fuel line @ filter turn key to on position should hear fuel pump run and get gas stream out of line. if no flow from line new pump faulty be sure & remove negative battery cable first good luck.

83 Chevy Silverado 454, New Battery & Starter- Won't Start?


first check if fuel is getting into the throttle body...take the air cleaner off and have someone press the accelerator while you watch for fuel to squirt into the throat. if there is no fuel then look at fuel delivery problems. If you do have good fuel flow then take out a spark plug and examine it for fouling or possible flooding. If it isn't then proceed to check for a spark. put the spark plug into the spark plug wire but NOT in the engine. with gloves on and wire and YOU are away from moving engine parts and belts and away from the area where you removed to spark plug. Place the top part of the spark plug and make it contact a solid metal part that has a good contact to the chassis...to allow for a return path for the spark. you can hold the wire far from the spark plug to avoid a shock. have an associate start the truck and make sure its producing a nice white or blue spark....red sparks are weak and no sparks is of course ignition issues. hopefully this will help with moving on with troubleshooting. we would need more info to move on or spend a month listing all the possibilities. :-)
