Okay. There are several things that can cause an engine to lose compression. Broken piston rings, a hole in a piston, bad headgasket, timing wrong, bad valves...etc.. these are all major internal issues with the engine except for the timing. However, most of these will cause a LOW compression issue, not a 0 compression issue. When there is a complete loss of compression, unfortunately there will need to be an engine swap. The reason that you would be better to have your engine totally replaced is because after labor and parts it will be much more economical to just buy a whole new engine. Possible causes of an absolutely no compression situation would be: excessive carbon buildup causing the valves to stick, the valve seat has popped out, ring or cylinder wear or ring breakage, or the head gasket has blown. If it is to be found to be the gasket or just the rings go ahead and get them fixed but if it is anything more than that I would not even bother with the present engine. Any questions after this posting you can forward them to [email protected]

1996 Suzuki DT30C outboard- won`t start. I installed a starter last week. It ran great. Now it won`t even cough, nothing. I pulled out the kill switch & cheked, it has connectivity.

Check for compression. If it has fuel and spark and compression it should fire. If the compression is low it will not run.

No compression

A car won't start without compression.
Request the compression numbers from him, if he hesitates he's probably trying to rip you off.

Randomly not starting could be a half dead fuel pump or just a loose connection under the hood causing sporadic spark to the plugs.

I have a b1700 that won't start, it wants to, but does not run. What should I be looking for

Possible low compression, could be due to a timing issue.
Check compression in each cylinder.

After doing a head gasket repair 2001 Chrysler Sebring 2.7 v6 won't start. It makes a noise like growling but does not turn over. My mechanic is saying we may need to rebuild bottom half but makes no...

You say that it does not turn over, how would you know there's no compression if it don't turn over, unless you mean if won't start up, lets go with it won't start up, if you have no compression, did you bleed down the lifter's, if you did not, with the lifter pump up will hold the valves open and you will not have compression, will be very hard to start engine, remove lifter and bleed them down, also make sure you replace the oil just in case there's water in the oil pan when heads were removed, if there is water could lock engne, now you would need to overhaul lower engine, hope this was very helpful.

Quad wont start got spark got fuel and got compression

If it's a 2 stroke you have a crank seal out. It can have compression but won't have vacuum, and it won't run. Sometimes the seal can be replaced on the magneto side without splitting the cases, but I'd rebuild the entire motor and replace the crank bearings along with the seals. Good luck!

My 2000 Dodge Grand Caravan will crank but won't start.

Hi, if an engine cranks but refuses to start, it lacks ignition, fuel or compression. When the engine cranks normally but won't start, you need to check ignition, fuel and compression. Ignition is easy enough to check with a spark tester or by positioning a plug wire near a good ground. No spark? The most likely causes would be a failed ignition module, distributor pickup or crankshaft position (CKP) sensor.

2005 chevy silverado won;t start.

i had the same problem, and it turned out the coil pack was moulding inside wich stopped the spark all together, i ended up changing my coil pack and putting on new wires because the ends connected to the coil were very corroded and that cures the not running part just fine
