I do not Know what kind of Diagnostic equipment You have ?? but
if you can monitor 02 Sensors and Mass Air Flow sensor see if anything looks erratic I usually run RPM at around 1000RPM and Run up to 2000RPM adjustments should be smooth and consistent with your Throttle position sensor held steady at 10 percent or so are Your sensors readings staying steady or jumping around if erratic need further diagnosis of sensor or replacement
also check crank sensor to timing see if they are in sync
next does it change any from Park /Neutral to when you put it in gear modern vehicle's rely a lot on signals from transmissions to control ignition

Good Luck Rickie

remove the spark plugs on the front and inspect. if the first one is wet and dark you need ignition coil.swap the coil with next cylinder clear code and run for a minute or till the check engine light come on.scan for code.if the code move with the coil you need coils.
if the code is the same run the engine and listen the injectors for ticking noise .crisp and clear noise is good.low tone or no click injector is bad.some times the wire going to the back is broken and will short two cylinder at the time

My 2000 toyota celica gts has no fuel pressure to the fuel rail

this may be a few things that would cause this problem, first is the anti theft system, try another key first and see if it starts, if so then key is bad. the next step would be to scan the computer for any stored codes as these codes will help alot in find the problem, but if thats no a way due to the car not running then the next step would be to check for power at the fuelpump. if theres power at the pump then the pump is bad. you can try having someone beat on the bottom of the fuel tank with a rubber hammer and at the same time try starting it and if it runs then replace the pump, if theres no power at the fuel pump then check all fuses first and then try swapping the fuelpump relay with another relay with the same numbers to make sure the relays are the same. start with these things first. good day.

Why has my malfunction indicator light come on my Suzuki Liana and how do I solve it?

The check engine light comes on when the vehicles computer detects a problem with one of many operating systems it monitors and controls. You will have to have a diagnostic code scan performed to determine which system the computer has found a malfunction with and repair as necessary.

Hi JHWalker
I would try doing the fuel pump filter or fuel pump itself if they are one unit.

Hope this help you.
