No Fuel/Hesitation/Need Help
I currently have this probelms:
1.I do not hear the fuel pump come on for 2seconds.
2.I noticed hesitation when i push the pedal to give it more gas and also feels like it was to die.But when i drive at low speeds about 20 and up it drives fine! Im i getting fuel to my injectors? or is it my TPS Sensor,Vaccum leaks??
3.No FUEL/OIL reading on my Gauge Cluster.
4.My exhaust pipe is currently hanging.Not connected to the Muffler.Would this cause some hesitation when acceleration is applied?
Items i have changed:
Fuel Filter
Air Filter
Oil Filter
Coolant Sensor
Sparks Plugs/Wires
Cap/Rotor
PCV Valve
Coolant/Oil has been serviced
Things i need to check test and replace:
Timing
Check for Codes
O2 Sensor
IAC Sensor
MAP Sensor
MAT Sensor
EGR Valve
Fuel Pump Relay
Coil
Pick up coil
TPS Sensor
Any tips would really help.Thanks for your time
