problems with my vr...again.

[brian101]

hey people i own a vr,yesterday i took the injectors off so i could tighten up the bolts on the manifold.im almost positive i put it all back together properly because i went for a drive after it was done and it was fine.but this morning it just wont start,it almost starts but not quiet.any ideas on how to fix it.

Have you done a code check-
Checking error codes VR/VS (Revised)

[brian101]

how do i do that

Sorry to hijack, mate just realised you're in geelong and you've got Liquid injection on your car (LPG correct?) just wondering where you got it done and how much it set you back?

[brian101]

just checked the error code and i think it came up as 33.does that sound right???any ideas what it means?

[nathanVY]

if you read the thread pjdm1980 posted theres a link to what all the codes mean

Code 33 - Manifold Absolute Pressure Sensor (MAP) high voltage.
New map sensors by the sounds of it, easy fix.

ok thanx for that.but were abouts is that located?

In the bottom of the first post there is a link in the word HERE.

Default Checking your Computer for Faults (VR - VS)

1. Locate the diagnostic connector under the the steering column on the drivers side.
2. Grab a paper clip and bridge pins number 5 & 6 'black' and 'white with black stripes' respectively on the ALDL (Assembly Line Diagnostic Link) connected which are located on the top row counting from the left.
3. Jump into the drivers seat and turn the key twice (so lights are up on the instrument cluster).
4. If you bridged out the correct wires 'Check Engine Lamp' will be flashing.
5. The flashes are divided into 2 groups with roughly a second between each. You can read the flashes as follows:

The first series of flashes is tens, so for example lets say the first flash simply flashes once, this means the code is 10. After the pause (~1 second) a second series of flashes will appear, if this number is 2, the code it is spitting out is 12 which means everything is fine.

6. Another example just so you're sure

The first series of flashes you count is 4 meaning 40, the second series of flashes is 3. Adding the 40 and the 3 will give you a code of 43 which means the Knock sensor circuit is experiencing problems.

7. Each code the computer picks up is repeated three times with ~3 second pause between, so its wise to sit there to make sure there isn't any problems it has picked up.
8. Once you are finished turn off your ignition and remove the paper clip. It is important to note not to drive the car around while have wires are bridged as this will prevent new codes from being logged.

Any questions or queries please feel to contact me at anytime.

Checking the computer for codes is used in conjunction with the computer Fault Codes located here

Mate I posted what code 33 meant AND the direct link to the page it's own.
Pretty clear, read over things make sure you understand what's being said.

The map sensor on a VR is green I believe, it's about the size of a matchbox and is attached onto the firewall just near the throttlebody. It will have a vacuum hose or two going into it. This could be malfunctioning. Source one from holden or ebay and replace it would be my next step.

would that code come up if he didnt put the map vac hose back on or knocked it off?
