Cranks but no start, fuel pump turns on...
Please help I have tried a lot of things changed the, MAP sensor, the Air Temp sensor, the Throttle body and spark cables NGK premium and battery all new. Still cranks but doesn't start. With carb and choke fluid cleaner starts only for 10 or 20 seconds and turns off again, while on I press gas pedal but doesn't accelerate. When key on I can hear the fuel pump turn on. I'm thinking it may be the ECU or computer.
used a code reader and the Map sensor, air temp sensor and pedal accelerator sensor are all circuit high permanent. Also cylinder 4 misfire. If it briefly starts means cranksensor and camsensor are fine it receiving spark also fine I think it's receiving fuel and air the key sensor light turns off after turning key so it recognizes it but still no start. What can I do to fix please HELP. I will appreciate very much any help. Thanks and family blessings to all.
