Can't turn over the lump

Recommended Posts

 I recently bought a 1984 Lotus Esprit that has been sitting for the past 15 years. We pulled the engine and changed the belts, hoses, clutch, plugs & wires. Now with the engine back in and wired up I can't get engine to turn over. All I get is clicking from the ignition & auxiliary relays under the glove box. The lights, horn, blinkers all work. At this time I don't have any water in the cooling system or gas in the fuel tanks, if that matters. Wondering if I can get some direction on this issue.

Thanks

Presumably the engine does turn, by hand.

 

So, does the solenoid on the starter motor engage, ie make a loud click?

 

Worth checking engine earth strap, battery earth (and the battery itself of course) and main feed from battery to starter.

Bit of advice to pass on, please DON'T run the engine without water, especially if it has an original waterpump.

I did, and fried the water-pump seal, a fragile carbon thing, which I then had to pull the engine to replace it. The heat generated by friction even on the starter is apparently enough to do this, though in my ignorance I did run mine at tickover for 30-40 seconds.

Even turning over you create fricytion on the carbon bearing and it will be kerput, engine out and start all over again. You can turn her over a little at a time by getting a good sized screwdriver onto the starter ring through the hole by the slave cylinder to make sure she has not locked up for any reason, then get water in her before going for a turnover by the key, assuming you have ignition, power etc.

Good luck.

Check the battery connections are good & tight, also the engine earth strap. :thumbup:

My specialist subject...the Absolutely Bleedin' Obvious.

 

I suppose the battery is fully charged?

 

Also, do the lights etc. go dim when you operate the starter?

Ok, sounds like I need to top off the cooling system first, will do. Battery is new & fully charged. Will check all ground & battery conections also.

Thanks

Ok, added coolant, oil & gas. Checked battery connections and ground straps, all good continuity. Dash & headlights work properly and horn & radio work. But still just the clicking from under the glove box, no starter ingagement. Whar is the immobiliser & where is it located?

How about the ignition cut off switch in the back right hand side of the car, black box with a switch on top.

Make sure it's pressed.

Ok, great news. A friend of mine, Mark an electrical engineer & machinist stopped by the Lotus shop tonight with his electric tester.

Found the relays were working correctly and power was going to the starter solenoid but not engaging. A few taps with a hammer to loosen it up and it turns over properly now. Very happy. Seems I get a running Esprit for Christmas! Thanks for all the advice.

Ah yes, an electrician with a lump hammer. Always handy to have one of those around. :thumbup:

Hey the magic tapping tool works every time. I would never be without one in my old tool box at work, used it all the time on our old engines. Mind you they were V12 2 strokes, bit like and Esprit realy as they screamed their heads off when running at full pelt as well.

Well done, another on the road for next year.

We had a Tiger Moth that always needed the impulse magneto biffed before it would work....watching those not "in the know" heaving the prop around uselessly was always good for a laugh....
