new- to me - spin , no start - suggestions

[don_1]

I must have got 60 miles on this new purchase. 5.0 1997 70,000.
Anyway, Hi , not on here often , hope you all like a challenge.
Ran well two weeks ago , stored with trickle charger, no battery problems.
Meta alarm , one fob.
With immobiliser on , no spin , no fuel buzz .
With immobiliser off, fuel primes, spins well , nothing else.
Under bonnet - found fuel presure on rail .
plugged in ecu diag cable and see throttle position working and temp 7c / 6c on guages.
Back under bonnet - found ignition amplifier . power to amplifier - no voltage, on red wire.
Any suggestions , diagrams/ pin-outs .

Thanks - needs to move so I can fix my daily

Verify you have 12 volts on coil positive terminal ignition on.

Welll.
Ok , plugged in all the cables to the ignition , fitted the voltmeter - dongle in, ignition on - 12.3V ish on both sides of the coil .
Then I wound it - started right up . 1st time in 100 attempts.
I let it warm up , 70 degrees on the dial , 30 psi , plugged in the rover gauge - 83 degrees 5% injector pulse , all fantastic.
stopped it - waited a minute - restarted .
Thank you, thank you - fantastic work - would recommend.
Lets hope it isn't the gremlins .
I will waterproof / spray cleaner in every orifice. ttry to squeeze the ecu back in its position , and leave it be .

Cheers from me.

Maybe the coil positive terminal is loose or slightly corroded. May have just been coincidence though that it chose to start and could still be immobiliser related if it cuts that circuit.

[don_1]

yes, I'll look into that.
was pricing up for a second dongle and blipper, Ouch .
I see one guy will refurb ( googling tvr alarm) .
Thanks again.

Most people just do the bypass and remove it out of the equation once and for all, if its just a weekend car you wont be leaving anywhere its very unlikely anyone will want to steal it.
