Hi, my name is ***** ***** I will assist you

Expert:  Joshua Haynes replied 3 months ago.

When you attempt to start your car, does it sound normal or is it seem to be spinning over faster than usual?

Customer: replied 3 months ago.
It's sounds normal the timing belt is still spinning
Customer: replied 3 months ago.
The car has cam codes but there is no fuel pressure does the cam sensor control the fuel pump?
Customer: replied 3 months ago.
Or should I be just looking at the fuel pump
Expert:  Joshua Haynes replied 3 months ago.

cam sensor does not control the fuel pump, just the fuel pulse width (injectors). The fuel pump should be working even with a cam sensor code. I would first start by looking at the fuel pump. I would check the fuel pump relay and fuse and also check the power to the pump literally. The easiest way to do it is to jump the relay with a paperclip and send power to it.

ok I got fuel pressure back but the car isn't starting still and I got code p0343 and p0341 for the cam sensor what should I be looking at ?
Expert:  Joshua Haynes replied 3 months ago.

see if you can pop the oil filler cap off and see the valves moving when disconnected. If the valves are not moving, then you have likely got a broken timing belt

Expert:  Joshua Haynes replied 3 months ago.

another simple thing to check would be to make sure that the wiring and connector for the cam sensor are in good condition

Customer: replied 3 months ago.
I took the timing cover off and the timing belt is still moving like it should I think it a wire issue to the cam sensor have you sen wiring issue with these car with the cam senor
Expert:  Joshua Haynes replied 3 months ago.

I have not seen a problem with the wiring to the cam sensors on these cars, but it does not mean that you do not have one. Do you have access to a scan tool that can read the pid data on the sensor live?

Customer: replied 3 months ago.
I should my snap on solus should be able to do it now its suppose to have a 5v reference on the grey wire right?
Expert:  Joshua Haynes replied 3 months ago.

That is correct, yes sir. Then there should be a sign wave for the signal that corresponds with camshaft sprocket position. I would look at the wave form on the solus first and then if it does not show one, start checking the wiring.

Hi, this is Josh checking in on your progress. If you have any other questions please don't hesitate to let me know. Thanks!

Customer: replied 3 months ago.
The 5v reference isn't present when I checked the wiring what pin on the pcm would that wire be so I can check and see if the pcm is sending a signal?
Expert:  Joshua Haynes replied 3 months ago.

connector j1 pin 51

Expert:  Joshua Haynes replied 3 months ago.

The pins should be numbered on the harness side

Customer: replied 3 months ago.
Were exacly is the pcm ?
Customer: replied 3 months ago.
I back pined the wire only getting .410v on the pcm side have you seen the pcm in this car fail a lot
Expert:  Joshua Haynes replied 3 months ago.

Oh, yikes, I hate to hear that bud. I have seen it a couple of times but I consider it to be a rare problem. If that is happening with the key on, then you seem to have a bad pcm

Customer: replied 2 months ago.
I replaced the car battery and the cam sensor code is gone now and I have the voltage to the cam sensor. But the car still wont start I got 4 codes that wont erase at all. I got p0118 for a coolant temp, and p2138,p0222, p0123
Expert:  Joshua Haynes replied 2 months ago.

Ok, at least you have determined the low voltage for the cam was just a battery...always cover the basics!

Are these codes new?

Customer: replied 2 months ago.
Yea these codes were not there before what should I be checking ?
