What could the problem be

It takes 2 elements for a vehicule to run fuel wise, a good mixture of gas and air. if you get gas, how is your air ? is the filter good ? is it dry ? have you tested the sensors like tps and maf ? also check pessure relief valve, it might be defective

Vauxhall signum 1.9 diesel 2006. High revs on start up and no throttle response


You have a draw leak in your fuel line causing it to do just what you've explained. Between the tank and fuel/injector pump and filter, it's sucking in air and pushing the air into the cylinders with the fuel cause a rich, very rich condition and that's why it is revving very high. Find and fix the line leak, start it up and stay at the switch in case of over-rev, until it calms down after getting all the air out of the system. I've been thru this a few times friend and it's a real pain not knowing the problem. Now YOU know.

Hw can i fix toyota hilux d4d 3000,2006 model cannot rev over 1500 revs


There are alot of factors that could prevent the engine from revving over 1500RPM. Some sensors like the crank angle or cam angle have to be connected in order for the engine to even start, other wiring loom plugs like the turbo controller need to be connected or the car goes into limp mode and it won't rev past a certain point.

Then there are the automatic throttle controller area wiring loom type plugs near the inter cooler, sometimes people forget to put them all back and the engine won't rev high. Making sure the vacuum pipes in this area are all connected properly, one unplugged pipe, no vacuum, the injector pump relies on the vacuum system and if it doesn't work then not enough fuel delivery, engine can't rev high. Also if the fuel rail is leaking or if the fuel filter is clogged then engine won't rev high.

Check your fuel pressure it should be 60-66 psi with key on and engine off.If its below 52 psi replace the fuel pump and filter.Sounds like it maybe a weak fuel pump.

1990 full size blazer starts fine idles then dies


sounds real easy either a bad idle air control solenoid or more likley a blown throttle body gasket. to test fro a blown gasket, with engine running and cool spray carb cleaner or brake cleaner around base of tb were it bolts to intake. when it hits the bad area, should idle down and be normal for a second or 2. iac is possible,try this first since its so common and let me know

My gfs 1999 blazer starts up, revs very high then shuts down. Any suggestions?


Sounds like a possible lack of fuel problem. Remove air intake hose from front of throttle body, then try spraying (carefully ) a little WD-40 into front of throttle body when it starts just to see if it will keep it running a little longer. If it does, your lacking proper fuel supply. Do you hear pump cycle (hum) when you turn the key to on position? I guess a good place to start if it is lack of fuel would be to change fuel filter. If it turns out to be something worse like pump, your going to want that filter changed anyway.
Let me know what you find.

My 1992 Chevy Blazer S 10 is revving really high when it starts


i have an s10 that would rev up high. i hooked up my scanner and it didn't give me much information, so i started researching. it took a while. i got my manual out and looked up all of the sensors in the fuel system. i even paid some web site $10 for help {wasred my $10} and they were no help. so i researched all of the sensors and found out their symptoms when they malfunctioned. the culprit turned out to be my water temp sensor. here is how it works, when you first start your engine the water is cold, the sensor sends out the information to the brain [warm me up] so your engine idles high to help reach operating temp quicker. when the sensor malfunctions it will send the wrong info to the brain [i'm cold] so the brain revs up the engine in an effort to get warm .i replaced the water temp sensor and the engine is back to normal.
