Pressure is a fast pulsing action, not steady?

hi, check the pulse on the injectors, fuel press. goes up to them, then the pulse to open the inj. is needed. inmobiliser can be set to kill any signal.

You may read fuel pressure but it could be a mixture of fuel and fumes or possibly bad or contaminated fuel. another possibility is that the fuel injectors are not operating. You need a steady 12v to one wire on the injector and the computer will supply a pulse ground to the other wire. Listen to the injectors with a stethoscope you should hear a clicking noise (pulsing) as the computer activates them

Bad driver in ECM/PCM

It sounds like you have a restricted fuel flow, which could possibly be a weak fuel pump or a bad fuel pressure regulator. Do a fuel pressure test to see if your fuel is being restricted. If it's only in the morning, that means its loosing its pressure over night. That could also be caused by a bad fuel injector. Test your pressure first.

if your talking about vehicle speed sensor, it is the sensor that monitors how fast a vehicle is traveling by how fast a gear in the transmission is turning and converts mechanical motion into electrical pulses and sends this signal to the speedometer on the dash as well as to the computer. if your talking about wheel speed sensor this is an electrical pulse generator at each wheel that monitors wheel speed and is compared to the other wheel sensors by the abs /traction control module to check for a differential to turn on the light and or apply brakes in the case of traction control system or release hydraulic brake pressure in the case of wheel lock up.

do you mean pressure on and off with the hp tips and smooth and steady with chemical tip?

it sounds like you have a air leak make sure all your fitting are tight if you have a filter make sure the filter isnt clogged if that doesnt fix it it sounds like your pumps ceramics might have been damaged in the pump its self

suuming that spark is good install fuel pressure guage and measure with key on and in start mode, pressure should be steady, 65 lbs or so, then check injector pulse signal,

sounds like electricul fualt. the bearing in the needle what holds them steady could have gone but that usely only happens on a accelarater needle

take batteries out control and put back in...turn off ps2 and while holding the button on the ir piece connected to ur ps2..turn it on and dont let go till game has fully come on...should work..if the red controller light still keeps blinking after doin it a few times then change your batteries
