Sounds like a distributor problem maybe cracked distributor cap or a bad rotor button the rotor button is bad about burning a tiny hole in it right in the middle where the contact point is pull rotor button off and look up inside where shaft goes in see if you see a burnt black spot if so the current from coil enters the cap and is distributed to correct cylinder as rotor turns but when this hole is burnt it comes in cap travels thru the rotor and burn hole straight to distributor shaft creating a no start condition have seen this problem make good mechanics pull hair out easily overlooked hope this helps if not repost at fix ya

Hello Friend:

Sounds like your timing Chain has Jumped a Notch or so.

To Verify it , Using a timing Light, Hook it Up. Have someone Crank the Engine Over Look Down on Can Camshaft you'll see a Mark TDC which stands for Top Dead Center. If your Timing Is Showing that you are at TDC then its not your Timing.

If its not at TDC on the Mark Loosen the Distributor hold down Bolt --And See if while the Engine is Being Cranked over.SEE if you can move the Distributor Clockwise and Counter Clockwise to see if you can get the Light to show its at TOP Dead Center.

If not before we Comfirm its the Chain Pull You Distributor Cap Look inside with a God Light Check for Cracks and check to see if your Rotor is Good To.

If ALL other Timing Related Componets we went Over are Showing Good and you never got the Timing Light to Show that your Timing was at TDC. Then it sounds like the timing Chain has Broke or Jumped Timing.

When you Replace the Chain Replace the Timing Sprokets and Tensioner also, They could have Caused this=Worn Sprokets or Faulty Chain Tensioner

Please let me know the Quality of my Solution was by Voting and a Testamony would be Appreciated.

Thanks for Using FIXYA From: d_hubbs

    I replaced timing chain. Is there a camshaft or crank sensor that would control spark on this vehicle with a distibutor? i replaced the pickup also the plugs wires and cap and rotor are 1 month old

My 1998 chevy blazer died going down the highway, what is wrong?


Multiple possibilities. Will start with easiest/cheapest. You don't mention check engine light (that would give codes), so I'll go with the same issue we've had with newer Blazers. That would be the ECM in the distributor. When ours started going bad, it would cut-off intermittently. Well one day the intermittent was terminal. Anew ECM, for the 2.8 V6 (1987) is approx 45.00. You would have to price it for your vehicle based on year and engine size. The worst case scenario is loss of timing gear. (That happened on our 67 Buick with 300 V8). Another thought is what happened to a friend. He's putzing on down the highway when his 88 Pontiac Grand Am simply quit. His computer had bit the big one. Those are the only things that come to mind, other than running out of gas or your alternator had quit charging your battery and the battery finally lost enough power to spark the plugs.

88 chevy 2.5l, gets fuel will not start


An engine shut not backfire unless the timing is off, it has a burnt valve or an exhaust restriction. Since the crank sensor was the catalyst for the problem, I would again check it. It definately affects the timing for the fuel and spark

I have problems with my 98 chevy k1500 pickup on the highway. Once i hit about 65 mph it wont accelerate and it backfires. also, after i come to a stop and try to accelerate up to highway speeds again,...


If it is running bad enough to be backfiring, the Check Engine light should be on. I would start with scanning the engine computer for fault codes.
