New car won’t start

[Mattbooth3598]

Hi I’m new here but anyway..... Having nearly finished my last project an mgb I’ve just purchased a solid, 944, 137k on the clock, anyway... I’m Having a nightmare with getting the thing going, having tinkered a bit I’ve found that both reference sensors are producing around 1077 And 1073 ohms.... all good, but when you crank you the car over, checking at the dme end of the loom there’s no voltage at all? just a bit lost with it all right now

Any suggestions welcomed?

Could it be a bad earthing strap? Also there seems to be a few suspect looking cables at the dme looks like something’s been disconnected ( I’ve attached a picture)

edit.... can’t upload The picture but post your email below and I Can email you

Does the tacho bounce when you crank the car

do you have sparks and fuel, you could be getting in deep before the simples

DME relay ?

I was thinking DME relay.

Also consider 944's wont fire until they build oil pressure

I think John's correct...DME will not pump fuel until it sees cranking speed of 200 rpm, I recall being the advice on here. Hope your battery is good!

dm.e; buy two keep 1 in glovebox, also known as spare dme carrier

Check the king pin on the distributor cap for corrosion where the coil lead connects, probably some corrosion on there with standing, it can cause havoc to running / starting..........trust me !

Really not a good idea in an open forum.

3 wire jump in the DME relay socket will eliminate the relay.
