Vin 6511 - Dan's 2nd Delorean

[Dan 6511]

What I did was unplug the thermo switch and linked the 2 pins on the connector thinking it was just a switch. Then cranked the engine with the injector in a glass and no spray at all.

Looking on the diagram, am I right in thinking with the switch unplugged I just need to ground one of the pins, the one with the UB coloured wire....?

Assuming the injector then fires when the engine cranks it would seem I need a new thermo switch

I still have a few left from the last lot Al. Can't make anymore though as no longer have access to a lathe where I work now

Tom has a lathe, could ask him to make some

Yes, it is NOT a switch.

Yes, disconnect the thermo time switch and link to earth the UB wire.

When you crank the engine the cold start injector should fire.

This test does not necessarily mean that the thermo time switch is not working. It only operates the cold start valve when the ambient temp is below a certain temperature. ONLY test thermo time switch with the engine cold. NOTE that if the cold start injector does operate with the thermo time switch in place, it will only operate the injector for about 3 to 7 seconds (I.e. to prevent flooding).

You could try some freezer spray on the switch, but I've not done this before, so this is just a suggestion.

Good luck, don't let the cold start valve cloud an issue of a poor start due to accumulator issues or the fuel pump relay not priming the fuel pump etc. ..

No problem. Don't want you spending money if you don't have to. It's my Northern tight-fisted DNA really !

I have only few set of shims courtesy of the very helpful Shane in Ireland. I did promise him that if any were used then the cost of getting them made go to him. €5 each I think.

I'll be bringing my fuel pressure gauge in Oct so you're welcome to use that.


Chris s is spot on with the cold start valve

Hi guys
I still have a good few shims left if anyone needs dem or u run out Nick I can pop dem over to ya in the post if you 've ran out
I think I have a few .5mm shims but most of dem are d 1mm one s as per admin bloke s specs
Cheers
Shane

I have bypassed the thermo switch properly now and the injector fires perfectly and it starts really easily now So I deffo need a new thermo switch.

I also did some stripping down inside but will post pics up tomorrow.
