If the timing is retarded due to cam and crank timing, the answer is YES. If it is due to distributor or ignition timing NO. Compression is produced mechanically when all the valves are closed during the compression stroke of the piston. If all is well (rings and valves), you should achieve optimal compression from the engine. Almost all gasoline engines require a least 80 psi to fire the cylinder.

What would cause low compression on a single piston engine?
The piston rings may be worn out .
Can low compression cause an check engine light to come on?
If it is causing the cylinder to misfire, yes.
What could cause low compression in all cylinders of a 1986 Isuzu Trooper with an inline 4?
AGE ! if it is low compression and not no compression then your piston rings and valves are worn too much and the engine probably needs to be rebuilt.
Low compression in number one cylinder in a 1.8 dual overhead cam interference engine?
Low compression in one cylinder can mean several things. The valves or piston rings may need to be replaced. There may be a crack on the engine, or the head gasket may have blown. The engine should be diagnosed properly to see what exactly is the cause of the low compression.
What should you do when a compression test reveals that compression is below average and the reason for a motor not working?
Low compression will not cause an engine to not run. It may not run efficiently but it will run. Low compression on all cylinders is caused by wear, and can only be fixed by overhauling the engine. Low compression on just one cylinder can be a blown head gasket, burnt valve, or a broken ring on that cylinder. I also depends on what you mean by "below average". An engine with lots of miles may very well have a compression reading that is below the factory specifications and not be cause for alarm. It depends on how much below specs that compression is. In any case, the only fix is to open the engine up.
Can a crankshaft sensor cause low compression?
No.
What would cause a diesel engine not to start if you have fuel and the engine is turning over?
Incorrect pump timing,low compression,fuel cut solenoid may not be working,
How do you know if your Hyundai lantra 1600 engine is losing compression?
When a Hyundai is losing compression in its engine the car will not run properly. Symptoms of low compression are misfires, stalls, and overheating.
Low compression in a 1.6 engine Honda in all cylinders. Any idea?
worn or broken compression rings engine needs a rebuild
How do you fix compression on your Lexus?
If you have low compression on one or more cylinders then you will need to pen the engine up to find the cause. It can be either a blown head gasket, burnt valve, or worn piston rings.
How can i repair a 1996 350 number 4 cylinder misfiring compression in cylinder is 118lbs the rest are about 160lbs?
sounds like your engine needs a valve job worn piston rings would also cause low compression ,but not cause the backfireing
Can low compression in car engine valve get restored in driving condition?
Only if you drive to a mechanic. :) Low compression is caused by wear, either in the piston rings or valves. Driving will not cause less wear to happen, so it will not make wear go away.
