Rb20Det Wouldnt Start

[poeticjustice88]

OK, I am new here, I have an rb20det calais. It's not running right, not sure whats wrong with it, but it just needs alot of maintenance.

The problem I had tonight was it would not start. cranked with plenty of power but would not start up. took about 5 minutes of trying and she came to life, drove for about a minute, got through a set of lights and just stopped. What it felt like was all my spark was gone. sat there for another 10 minutes trying to crank it over. it would start up and hover at about 300 rpm and then die. tapping the accelerator would bring it up 100 rpm or so then it would die. it felt as if it was only running on 4 or 5 cylnders. the coils are all good, as are the plugs. just wondering if anyone has had a similiar problem, or may know of something it could be.

These are the other two posts I have started asking for help, I am not expecting you all to read through them both, but I thought I should put them on here so that everyone gets the whole picture.

I unplugged one of the TPS connectors, the connector coming off of the side of the TPS, not the bottom one and it came to life after a couple more attempts. I do not know if it was because I unplugged the TPS or just coincidence.

Any help anybody has would be greatly appreciated. This is my daily driver and having it stalling on me is something that I can not handle.

Thank you all in advance.

Kind Regards,

the other plug on the tps is the for auto r32s. . is your calais auto?

[poeticjustice88]

calais is manual. both the plugs to the side of the TPS and the plugs on the bottom of it are connected

Which do I need?

[StevenCJR31]

its odd that its plugged in, is the loom factory or custom? from what ive seen manuals only require one plug ( not sure which one you require as my 32 is auto and uses both

plugs)

[poeticjustice88]

well i am not too sure. I believe the loom is factory. it definately seems factory.

would anyone be able to shed some light on how to test the tps. i tried the other day, and it was 0.00v or 12.0v. nothing in between, but that was me trying the plug coming off the side, not the bottom plug.

Which plug, and which pins should i test?
