88' Pontiac Sunbird non-turbo not starting but cranking has spark and compression but gas is pooling in intake and not getting to cylinder what are possible causes?

Is the compression ratio of a piston inside its cylinder measured mechanically or atmospherically?
Mechanically To put it as simply as possible. The cubic inches of a cylinder and the amount of space your compressing it into is the compression ratio.
Cylinder 5 misfire could it be the coil pack?
it's possible, also check compression, fuel supply, and vacuum leaks.
What does it mean if you do a compression check and there is no compression?
It just means that the railway is not compressed. Say that the railway was compressed, then you'd make a compression check and the answer would be positive, but if it isn't it means it's not compressed. When something is compressed, it means that the temperature was too cold for the railway so it compressed. Hope it helped! :P WHAT???? this person is lost. Ok, when you do a compression test and you receive no compression, make sure your test gage is a working gage. with no compression this indicates that exhaust / intake valves are in the open position which stops the cylinder from sealing for compression, possible bent or broken valve,valve spring,or lobe on cam may be worn. Now if you have a low compression reading on a cylinder i recommend you spray WD 40 into cylinder sparingly and test again,called a (wet test ) if compression raises you have bad piston rings, if it stays the same, its a valve issue, possible piston failure
What kind of battery do you need for a 1990 Toyota 4runner 4-cylinder 5sp?
Min 450cca Battery but try to get as most cold cranking amp in the battery as possible. 675 or 775 series
What is the cylinder compression for 2.0 engine?
There is no real compression spec for the 2.0 zetec engine. Ford only says that no cylinder should be below 25% or all the cylinders. If it is that cylinder is down. That could be a number of problems such as head gasket or bad rings. Either way. Once you do a compression test yourself I would recommend having a dealership follow it up with a diagnostic. They will be able to give you solutions if there is low compression as far as possible reasons and repairs. Per. ALLDATA Ford NTI/ UTI student
Your 99 Explorer's service engine light keeps coming on It's always 4 cylinder misfire cold start changed wire and plug what gives?
Think a little deeper. Combustion that fails is a misfire. You have addressed the spark side of it. There is a fuel and compression possible trouble. Try swapping the fuel injector for that cylinder with another and see if the misfire moves to the other cylinder. Compression test the cylinder to see if it is in specs. Try a cylinder leak down test and see if it is losing compression. Perhaps there is a carbon build up on the valves preventing good seating?
Possible causes for over heating of 1994 Toyota 4-runner?
A compression check and cylinder leak-down test should tell you the condition of your engine.
What is the cylinder compression on a 1994 Isuzu trooper?
I'm not sure of the exact values; they should be in your Haynes repair manual. However, if you compression test all of the cylinders and find one that is lower you have a compression problem with that cylinder. It is also possible to have 2 that are lower, this would most likely indicate a warp in the head between those two cylinders. Other causes for compression loss are damaged or gunked up valves that do not close all the way or a crack in the head.
What causes an engine to lose compression?
Low Compression usually means that the cylinder rings are worn. You should also do a leak down of each cylinder. That will pinpoint which cylinder/s are bad. Also,possible poor seating of valves or improper valve seat contact.
Possible causes of a loud knocking noise from the engine of a kia sedona 2003?
Is the oil lever OK ? Also get a compression check in each cylinder to see if one of the piston rings have worn out.
Why would a 1997 LT1 miss on one cylinder if the spark the injector the compression and valves are working properly?
possible bent, warped, or torched valve - bad valve seat - or worn valve guide
What are the possible causes of a 90 Ford Tempo cranking but not starting?
batt is 1yr old or less, fuel pump seems to be working as I smelled gas after cranking for about 10 seconds straight.
