Having problems with your 1998 Chevrolet Astro ?

Vehicle unexplainably ran rough and now won't start

\015 I think my timing belt needs to be replaced, how do I know if it does?\015 Posted / edited by AnonymousUser on : 15-01-2018

Answers :

If it no longer starts, the easiest way to check for timing chain failure is eyeballing the distributor rotor. You'll need a helper.

  • Pull the air filter assembly
  • \015\012
  • Loosen the distributor cap mounting screws. (They won't come completely out) Some distributors have 'half-twist' fasteners that look like screws. With these you push down and give it a half turn.
  • \015\012
  • Pull up on the cap and set it aside.
  • \015\012
  • In side you'll see a round plastic thing with a piece of metal going from the center to the outside. This is the rotor.
  • \015\012
  • Have your helper turn the engine over while you watch the rotor. WARNING: Keep clear of the engine while doing this. It won't start, but it can still cause damage.
  • \015\012
  • Is the rotor turning? If not, your timing chain is broken.
Hope this helps,

91 acclaim v6. starts and runs good, but once its been running for awhile (hour or so), and i turn it off, it doesnt want to start back up, or does and dies. wait 2 hours and it starts right up. recently happened again but i didnt wait 2 hours and kept trying to start it. it did start but ran rough then died and hasnt started since. plenty of gas and i think i can hear the fuel pump. engine turns over but wont start.

Did you replace distributor cap and rotor? These are common on these engines. If you pull the cap, look at the contacts on the cap. You will probably find a lot of build up on them. ... 1995 Chevrolet Tahoe

I have a 1991 sonoma/s-10 (v-6) and its hard to keep running after its started,rough idle. When driving the motor will sometimes backfire and cut out. After about 1 mile or so of driving the problem goes away. When the motor is again started ,hot or cold the rough idle problem comes back and sometimes wont stay running at all until its ran for a few minutes. I tried all the tune-up stuff and still have the problem. Any help would be much appreciated.

The engine suddenly started running rough, added fuel injector cleaner, ran that through for ~10 miles and then refilled tank with high octane fuel, still rough, exhaust smells strong like rotten egg, and the exhaust seems much hotter than normal. Also the check engine light is flashing, my code reader does not work on this vehicle so don't know what code it's indicating. Do you think it's an O2 sensor, MAP sensor or spark plugs? Car has over 200,000 miles ran fine until now.

I have a 2004 dodge stratus that wont start or turn over, the dash lights head lights and radio work but just no start or attempt to start however it will start when being jumped by another vehicle but will run rough and backfire and then shut off. The battery is good I've checked all the grounds in the car. I don't know what the problem is and it's driving me crazy.

No idea without a play under the bonnet but try charging the battery up so it starts on its own then see how it runs, a low voltage will cause the symptoms you describe ... Cars & Trucks

99 4JX1 Jackaroo presented with hard start and running roughly / cutting out. I have replaced the injector harness (full of oil) the ORPC (set factory default and vehicle started and ran) and the gaskets on both oil pick ups in the sump. No DTCs now but will start and run well for several minutes before dropping rail pressure. It usually stalls shortly after but if it doesn't it struggles for a bit then pressure resumes and runs well for a little while before repeating. (monitored with Tech II)

Wont start I got home form a 37 mile trip from work and the car sat for a couple of hours and i went to get back in and it wouldn't start. I finallly got it to start and it ran rough and white smoke came out the exhaust pipe. I checked the oil and it looked fine but it was low on coolant. I did an oil change 3 weeks ago and all levels were fine. Does it sound like the intake manifold or head gasket?

Yea the white smoke,low coolant and probably overheating. sounds like poss cracked head or head gasket... intake maybe but i think thats wishful thinking... ... 1997 Buick LeSabre

Check engine code po301. replaced coil packs started up once ran rough and wont start again. White smoke coming out of exhaust while cranking. THis is on a 1998 olds 88, 3800 engine.

Hi Guys, Greetings from the middle of nowhere. I am currently in Tanzania on an African trip from Cape Town to Cairo, so finding an english-speaking mechanic seems impossible!!! The problem started a few days ago as i was going up a mountain in low range....carrying half the village on the back! Almost at the top, the engine started to idle very roughly, so much so that the whole vehicle would shake. If i raised the rpm to jover 1000 the shake diminished a little and at higher revs it ran fine
