So my 1998 chim 400 was running a bit rough.. bad idle, stuttering under light load... took it to my house and replaced the dizzy cap, rotor arm leads and ignition module.. Won't start...!!!

.Turns over fine, strong battery..
.Strong spark at king lead end
.Strong spark at plug end.
.Leads in correct places

.fuel pump priming
.both relays working
.fuel at high pressure rail
.power to injectors
.Injectors pulsing

No start..

Can't see fuel on the plugs if I remove one after turning it over.. it's moist but not dripping wet...


Any ideas?? I'm not a mechanic but I have a tool kit... Also had some phone support from the great guys at Amore but at the moment we kinda stumped...

I would take a step backwards if it used to start, aftermarket parts can be junk.

Leads all correct places. Parts are all Lucas although I have done some swapping back and forth to double check

I beg to differ. 25 years ago, they were the go-to company for ignition parts, starters and relays too. There were shops that stocked their stuff. But the present owners have allowed the name to be stuck on 'out-sourced' stuff. frown

It could be the ECU as a pulse from the ignition amp when starting signals the ECU to switch the fuel pump on if this is not happening your plugs could be damp from the initial fuel pump prime.
Where are you in the UK? Someone local may have an ECU for you to try.

Ha ha.. yeah the original ignition amp say "make in UK" the new one is "made in Korea" .. How times change but the spark seems really good. Only a visual observation but it's clear and strong on daylight. King lead is arcing over 10mm.
I'm gonna get some easy start in there and see if it fires just so I can discount the ignition side though. Pretty sure it's not getting fuel.
Unfortunately I'm in Spain so there's not a great wealth of TVR experience although they do have alot of old range rovers..
