98 suzuki esteem. getting spark and gas but wont start it is a 1.6l motor and i cannot figure this one out any suggestions?

Spark plugs in your case 4.
New air filter.
Carburator cleaner to clean the throttle body.
In case you want to change the oil, oil filter and 4 quarts of oil.
In case you want to change transmission fluid, 5 quart of transmission fluid and transmission fluid filter

1.6L or 1.8L
400s are evap or EGR.

EVAP Pressure Sensor Range/Performance

reset it, tighten the gas cap, and see if 451 come back.
or a new cap if it leaks.
if not that, then the EVAP venting system needs pressure checking next. (takes tools to fix cars so....) get it serviced.

You can try some starting fluid sprayed inside the air cleaner box.
An engine needs 4 basic elements air, gas, spark and compression.
It is a good idea to test for all 4.

Hi
Good chance is you wiper motor is blown.
check the motor

Th engine must be prroperly tuned for the LPG if this was fitted externally . If this was factory fitted please get a proper fuel setting done on the gas , check the spark plugs , the intensity , and also the timing.

clean/change maf sensor maybe

the fuel pump is in the tank, and the spark plug wire's could be hidden under a plastic cover on that motor

Check to make certain you have connected the spark plug wires correctly to the distributor cap! They are NUMBERED. If you have them connected incorrectly, you will receive a misfire.

I would first check the spark plug leads. If your car is a G series engine, then the long, plastic ends that go on the plugs down inside the head break down over time and with heat, and little burnt spots on them will signify the leads are shorting to earth. This may not be a problem at low speed/low load, but when the engine is under load, the spark wants to go anywhere other than to the spark plug. This problem may not be there when engine is cold, but if left, it will be there all the time (if it is the leads). Good luck.
