Chimaera starting problems
Discussion
Bypassing the immobiliser may be a solution but is a bit drastic without first confirming that is the issue.
Some testing would be a better start point.
Does the engine crank? If so then the major fail points of the immobiliser are not present.
Pull the fuel pump relay and with a piece of wire connect pin 30 (purple/white wire) to pin 87 (black wire) and see if the pump runs then report back.

There are lots of things to rule out before you get to the immobiliser, and the check which Steve D has asked for is an excellent starting point.
Also, sorry to be a PITA and all that but can we verify you’re a Chimaera owner before we start discussing how to circumvent our vehicle security systems - which also shouldn’t be done on an open forum.

Pretty much every week for the last four years someone has contacted me by PM for my immobiliser bypass instructions, I think this probably has a lot to do with what I call the 'Magic Bullet' trap. Human nature is such that people all too often make the mistake of adopting an optimistic belief there's is some sort of 'Magic Bullet' fix out there, the uncomfortable truth is of course a little more effort and application of grey matter is needed.
You could just blindly trow parts at a problem or make assumptions like "I need to bypass my immobiliser", you may even get lucky and fix the issue, but make no mistake it would be luck. I would urge you to consider if you'd be happy if your doctor adopted the same diagnostic approach, or if you might prefer him to run a few tests before he refers you to the surgeon for open heart surgery.
Bad mechanics throw parts at problems just as bad doctors throw pills at them in their trade, so while I have already responded to your PM with my immobiliser bypass instructions Charlie, I make no apologies for the first two thirds on that email being about the other things you should test first. Good luck with your diagnostics, start by studying the system and truly understand how it should work, then run some tests, this way you only fix what's genuinely broken.
Finally, if you do end up proceeding with the immobiliser bypass please be reassured unlike a heart bypass... its reversible in seconds!

Hi Dave,
Does the immobilisor control the injectors or injection system?
I have a starting problem but fuel ok, spark ok and fuel pump priming.
thanks
Not directly no.Does the immobilisor control the injectors or injection system?

Do you have rovergauge? Well worth having as it will tell you many things to help diagnose your problem.

Please be reasured my bypass instructions are designed to be completely reversable in seconds, you could even complete the bypass as a switched circuit allowing you to turn it on & off at will.
As such a bypass really isn't the drastic operation some are suggesting, it's also been executed by litrally hundreds of TVR owners who are now able to start their TVR reliably. A bypass is not only reversable it is all so to all intents and purposes completely free, over the years hundreds of Griffith and Chimaera owners have used my instructions to save themselves hundreds of pounds on a new security system.
For many years David Beer was peddling his hot start kit claiming it was the magic bullet solution, unfortunately because he failed to understand the true cause of the problem many were duped into buying this kit which is just a realay and collection of wires, not only was it ill conceived but it was also poorly made.
Ironically because the hot start kit adds a fuse, a relay and a poorly made loom it actually adds a series of additional points of potential failure so if you have this kit installed you are strongly advised to remove it, at best it adds a number of additional points of potential failure and at worse it does so while also giving the owner a false belief he's fixed his hot start problem.
Typically the Meta system that was incorrectly wired to our cars by TVR are 20 plus years old now, bypassing it is easy and as I say is completely reversable in seconds, as such its nothing to be afraid of. However, despite the immobiliser being a known issue, before you jump to conclusions you must complete all the logical diagnostics which is why my instructions start with this before I even get into explaining how to complete the bypass.
You'll never prove the true source of your starting problem until you complete some basic tests with a multimeter, for example the issue could quite easily be a faulty hot start kit if one has been fitted as this dreadful thing only serves to introduce a series of additional points of potential failure, and merely adds to the already woeful spaghetti like mass of wires TVR just left hanging precariously in the passenger foot well.
