help!!!

ok well i replaced my spark plugs and wire, crankshaft and camshaft sensors, o2 sensors, and the sho still takes along time to start up. It keeps cranking and only the second turn of the key will it start, but even when it starts u have to keep giving it gas for about 20 seconds, or otherwise it will stall, after that it runs fine....i dont understand why?? please someone help...

Oh yah, and when i run the codes it comes up with a powere steering sensor....what does that have to do with it??

Check your fuel pressure. What kind of plugs & wires did you use?

 

[masho95]

What type of codes are you trying to run? KOEO or KOER? If you are trying to run the KOER codes perhaps you are getting the code for not turning the wheel before you get the signal flash for the brief WOT. When running the KOER test you need to turn the wheel and push the brake for the BOO to be registered, after that wait for a single flash and press the gas to the floor for a sec to register WOT. After that read the codes again. Hope this helps.

Its a computer i bought from autozone, i have no clue what kind it is?? my feul pressure is good, but someone told me it might be somekind of valve on the feul line...or a coolant sensor temperature...what do u guys think?

Turn the key on/off a few times before starting, see if that helps. You should connect a fuel pressure guage and monitor it while starting and running it. You want to see if the pressure ever drops below specs.

This sounds like the camshaft position sensor, but since you replaced that, I don't know. See what kinds of codes it throws and let me know.

Sometimes it takes a few primes of the fuel pump to get my fuel system up to the proper pressure to start the car, otherwise it will take longer craking it to start it. I can hear the difference in pitch from my fuel pump as it primes the system.
Can you hear your fuel pump when you switch the key to ON?
Try replacing your fuel filter, too.

yah if i turn the key from off to on a couple times and try to start it, its starts up fine, but still sometimes even after i do that, it feels like its about to stall so i give it gas for alittle bit, while doing that sometimes it backfires in the intake, but after gasing it for a while it idles good after that, and drives fine...hmmm..

Let me try this again...

CHECK YOUR FUEL PRESSURE.

You say in a message that your fuel pressure is good, yet you didn't indicate that you had actually tested the pressure. If you tested it, what were the PSI results?
