95 Neon

I Just Changed The Timing Belt On My Sohc Neon. It Was Free So I Said Hell Why Not. Anyway, The Belt Was Chewed Up Pretty Bad And The Tensioner Had Snapped. I Got The Codes Pulled From The Car And It Showed A Camshaft Position Sensor Fault. The Mechanic Said That Was Because Of The Timing Belt. My Question Is Would A Bas Camshaft Position Sensor Cause The Car Not To Start? It Sounds Exactly As It Did Before I Replaced The Timing Belt. I Have Done The Obvious, Battery, Fuses, Etc. Im Stuck!!

I just did a belt on a 97 and the first time I put the belt back on and tighted the tensioner the crank moved. So I took everything off and was very carefull this time and double checked to make sure the timing marks were in the right place.

If you know you did this right then I would say start at spark and fuel. Maybe compression test.

When it turns over you can watch the can shaft and make sure the valves are all moving.

I wouldn't think the camshaft sensor but this is a distributorless car so I am sure the sensor has something to do with spark

Good luck and post more

thanks :biggrin:

Yeah I Will Try That Later. Its Weird Because After I Tightened Everything Up I Cranked The Motor And The Timing Marks Were Lined Up. Crank And Cam. I Was Looking At The Rapair Manual And It Says To Back The Crankshaft Back 1/2 Notch. Then Its Says Later That The Timing Marks Should Match Up. I Will Try To Test For A Spark.

When this thing happened to me I ended bending all of the intake valves, so do a compression test and find out.

IN REGARDS TO THIS, WOULDNT YOU HEAR SOME SORT OF NOISE IN VALVES WERE BENT? I MEAN WHEN YOU CRANK THE ENGINE OVER.

not always, if the pistons got grooves from hitting the valves no. It depends in how much you bent the valcves. sometimes you dont bent the valves enogh to cause much noise, but you bent them to loose compression.

I Leave Work In An Hour. I Am Gonna Stop And Get A Compression Kit. I Will Let You Know The Results Tomorrow. Thanks Everyone!!

The neon must have cutouts in the pistons for the valves because when we had the belt off and the head was on #1 TDC. we plasti-guaged the rod berrings. We had to turn the crank to get to #2 & #3 and it never hit anything.

good luck

Okay. I Checked Compression Last Night. The Gauge Did Not Move At All. I Checked Each Cylinder And Got No Movement From The Gauge. I Am Starting To Believe That My Valves Are Bent. Could I Have Done The Compression Test Wrong? I Didnt Hold Down The Gas Pedal And My Engine Was Not Warm. It Wont Start To Get Warm. I Am Thinking About An Engine Swap. I Hear That They Run Like $500 For A Used Neon Engine.

Your valves are probably bent pretty bad if you are getting no compression. Neon engines are cheap and plenty to swap in. $300 from a junkyard and you can be up and running in no time. That or you can replace the valves.

I WILL PROBABLY JUST CHANGE THE VALVES. IT ACTUALLY SEEMS CHEAPER FOR A NEW ENGINE WHEN YOU FACTOR IN THE NEW GASKETS AND BOLTS THAT I WILL NEED. I WILL LOOK INTO A NEW ENGINE AND HOW MUCH IT WILL COST TO INSTALL. I TRULY DO NOT FEEL LIKE TACKLING THAT JOB.

YEAH, Just do a engine swap, I tried doing a Head Gasket and it would never start made sure everything was perfect notches matched just wouldn'r start. So I swap motors and Happliy Ever After. Motor cost me $350.

I Went Ahead And Took The Cylinder Head Off. The Valves Look Good. I Havent Taken Then Loose Yet. Can You Tell If They Are Bent Just By Looking At Them Or Do They Need To Be Removed And Examined?

If the head is off then pour a little water around the valve seats.

I WILL TRY THAT. ALSO IT SEEMS ALL THE EXHAUST VALVES ARE STUCK OPEN. I REMOVED THE ROCKER ARMS SO THAT THE SPRING IS EXPOSED. AND ALL THE EXHAUST VALVES ARE OPEN. ALSO ON THE INTAKE VALES, THEY APPEAR TO BE BURNT. LIKE A WHITE CRUST AROUND THEM.

If the head is off then pour a little water around the valve seats.

GOT THE VALVES OUT. ALL OF THE INTAKE VALVES ARE BENT AT LIKE A 35 DEGREE ANGLE. THE EXHAUST VALVES LOOK A LITTLE OFF, SO IM GONNA REPLACE ALL OF THEM TODAY.

After you do the valves, the engine should be good to go for another 100,000 miles :p

THE TIMING BELT WAS ACTUALLY LIKE WOOL. JUST WADS OF WOOL. NO BELT EXISTED WHEN I GOT THE CAR. PRETTY BAD.

That happened to me once!!! I had to replace the valves. the cause for this in my neon was that the tenssioner broke, so get one of those wile you are at it.

Okay I Have Rebuilt The Head. Car Starts Fine Then When I Went To Put It In Reverse It Went Forward. Now When I Put It In Gear It Does Nothing. I Checked The Fluid. Way Too Low. So I Added Some. Still Nothing. If I Rev It High Enough It Inches Forward. Any Ideas?

Did tou remove the transmission?If so then did you prefill the torque converter?That in my experience is usually the problem.

no i never removed the transmission. the car was sitting for a good 2-3 months before i got it from a friend. im thinking a good trans flush. i will try that later.
