Rb26 Turns Over, But Wont Fire

[N1GTR]

Guys, my gtr has been sitting around for a while without being started, and i tried to start it today - no suprise, a flat battery

So i get the jumper leads from the other car and hook them up, the voltmeter shows almost half way, i turn it over and the starter motor is working, but the engine wont fire up

What would that be?

The manifold pressure keeps rising as it tries to start ive noticed.

I cant roll start it - so that is out of the question

Thanks in advance

Not enough voltage/current?

Turning over slow?

Try a better jumper battery, larger jumper leads or charge the battery overnight.

cheers

PS, you're a naughty boy, you should drive your GTR everyday.

It turns over at normal speed to start, then gets slower until theres nothing

Ive tried letting it charge for a while, but nothing

I also noticed the tacho goes spastic when the starter motor is trying to start the car

How would i charge it overnight?

Your also trying to push power from the jumper battery through the dead cells of the other battery. Overnight charging will be needed, also the cranking will be filling cylinders with fuel....not good for the plugs.

How do i charge overnight?

With a battery charger

[N1GTR]

OK, thanks for that, ill have a look around at home - theres probably one somewhere in the garage

or just swap the battery over for a charged one to start the car. Trickle charge the other overnight via a battery charger.

I think ill just get a new battery

They cant be expensive, ive never had to buy a new one though

Thanks guys!!!

i had the same problem. had not driven mine for a while and it didnt turn over.

ended up being a loose earth feed behind the rear seat for the fuel pump.

weird huh.

i had my car off the road for 4 months while respraying... then it never idled again after that ..

ECU shat itself somehow, didn't work til i changed to pfc..

battery for sealed 550CCA should be around $140

Steve, my car went flat while I was in Japan and there wasnt enough current left to jump it, or to register a charge using the trickle charger.

I got around it by connecting jumper leads at the back, connecting them to another car to get charge going in, then connected a charger to the terminals in the engine bay, which then registered charge.

Left it for 24 hours and hey presto

That said, it sounds like there might be another reason for your car failing to start

[Guest Mashrock]

you havnt disconnected the crank angle sensor? or some of the fuses?

[N1GTR]

Just tried again (and did whats mentioned above) and...........it fired up! cheers guys

[Guest Mashrock]

was it the crank angle plug??

get a marine battery they last for ever

[N1GTR]

It was the battery just being so old (and a pain in the arse)

Ive got a new Century battery for it - -its super heavy duty so it should last ok
