Hello I been having trouble with my S14 KA24DE; Did a complete tune up Cap, Rotor, Plugs, Plug Wires, Coolant Temp Sensor & Fuel Filter.

car starts but bogs down then engine cuts out.

if I spray starting fluid it runs off starting fluid and idles and revs fine;

I even re-wired Kragen Fuel Pump to 12 volts via Relay it runs a little better but once I rev it, engine bogs down and cuts off.

also if I unplug the MAF plug idle is higher. not so sure if it is Fuel Pump crapping out any advice?

Also while engine is running I pulled each spark plug wire off and its sparking also unplugged each fuel injector wiring while its running there is a different also Fuel Pump sounds kinda weird when at the on positionthanks

if your car runs with the maf unplugged than you need a new maf tps or temp sensor

I figured out what my problem was, removed fuel hose from fuel filter let fuel pump prime barely anything came out of the hose unless cranking so its a fuel problem also if you unplug maf all 240's should be able to run but in limp mode won't rev past 2k
