ga15de wont start GA15DE wont start and little press on gas pedal engine stop

[ireena6]

hai, i own ga15de on b13 swap from carb engine,

1.my problem ia engine wont start either cold or warm, i have to pour little gasoline to make it start,

2. when pressing gas pedal, it stop,

what cause it, dont now what/up to do now, just courious, is it injector/tps/fuel filter.

just renew and install the fuel pump,but problem is still persist. pleasei need assist what to do.

Does the engine run at its steady idle speed once you get it going?

If so, check TPS first. On this engine TPS is a simple 3-terminal device which can be tested with a multi-meter. Also check for possible vacuum leaks behind the throttle including those caused by possible cracks in injector washers.

tps check. supply volt 5v,
throttle full closed, 0.45 - 0.47v. cold
throttle full open 4.9v..
is it ok,

No. That much is not enough. TPS is just a variable resistor but it should give a smooth seamless variation in resistance value in proportion with the throttle angle. When you checked for above voltages you should have moved the throttle very slowly and observed for smooth variation in voltage. Usually TPS units get worn out close to their idle position because that is where the most frequent movement occurs.

when idle, tps give 0.45v, slowly move the acceleration cable,volt increase every movement till full open throttle given 4.9v...
il check it again the smooth variation in voltage,1518769624899
