Won't start :-(

[RebelV8]

The saga continues............

I've had the engine running (2.4), by using easy start to persuade it to fire up. left it to warm up for a few minutes, then turned it off, tried it again without easy start about 10 to 15 minutes later and it fired up off the key. Left it overnight and tried it again without easy start and it wouldn't fire up at all, flattened the batteries this time. Charged the batteries up overnight and tried again, still wouldn't start. Checked that fuel was getting through by cracking the injectors and pressing the plunger on the filter housing (small amount dribbled out), still wouldn't start. Checked the glow plugs and they were all black from the tip to where the thread starts, replaced the glow plugs with new NGK ones and tried again, still won't start. Lost for idea's now.

Timing is all set correctly,
There is fuel getting through,
Earth's are all connected and good,
All pipe work is connected correctly,
It will only run when easy start is used to persuade it into life.

Any idea's?

The diaphram in the primer has probably perished and letting air in causing the fuel to drain back to the tank overnight.

Fully charge the batteries again then in the morning, get someone to continually pump the primer as you crank the engine.

When I was pushing the pump on the primer, every time I let go of it and it rose upwards I could hear a sucking noise. Could that have been it sucking air in?

Is it possible to take the primer apart and replace the diaphragm if it has perished or do I have to replace the whole unit?

Thanks Vince

It shouldn't make any noise really, a sucking or hissing noise would indicate a vacuum isn't being created as you pump it. There's possibly a spring under the plunger to help raise it.

I've never taken one apart, so I don't know if they are serviceable.
You could temporarily bypass it with a small in-line filter to see if the engine starts easier. (Once the fuel has been drawn from the tank via cranking the engine.)

I'll investigate further and see what I come up with then.

Thanks again

What he said

I've had this on my Avensis

Glow plugs are the usual suspect too.

I should really read all the posts before commenting..doh

[RebelV8]

Don't worry about it, all comments are good ones.

I managed to get a replacement primer unit from a local scrap yard (they had a Surf bodyshell in). I'll test it at the weekend after replacing the back box of the exhaust on my Mondeo, rebuilding the air filter system an my wife's Frontera and trying to get a bit further with converting my Charger from power steering to manual - depending on the weather that is lol

Fairly certain that I've found out why it won't start without the assistance of some drugs,
The 80A fuse is blown!

Of course I didn't find this out until it was too late to try and buy one and tomorrow being Sunday means I can't get one then either.

Must admit though, it would be nice to know what I did to cause it blow so that it doesn't happen again

[Sylux]

80A is pretty high to blow, too!

Easy done really, if you don't rebuild the bus bar insulator in the
correct order, all you have is a dead short.
Hope this helps.

Wish I read this yesteday, I could have posted you one...

Bugger, wish I'd known that as well, lol

Replaced the 80 amp fuse, connected the batteries and the fuse blew again, I've obviously connected something wrongly. I've attached a pic of the stud that the insulators and power supply attach to (circled in yellow), does it look right or have I got it wrong?
