Need help m50 NV 92, crank no start

[Matt-B]

ok ill try that

[416stroker]

no real fuel . put like a half a paint cap in the throttle body. If it evan wants to run is shold run for 3-4 seconds. dont use starting fluid thats stuff all bad.

[Matt-B]

like starter fluid, and pulling fuel pump relay and fuse? yes I have

[416stroker]

Have you tried disabling the fuel pump and priming the manifold with fuel to see if you can even get it to fire without the pump running?

[Matt-B]

If my DME is not getting power from my C101, will i still get fuel and spark?

[Farbin Kaiber]

I also stand behind the hardwire option, but in a different manner, tie into the e30 m20 harness behind the connector. Then you still have an engine removal harness quick disconnect.

[Matt-B]

My adaptor had like the coolant temp wired into DME power, not sure what that would have made car to, jumping car soon AGAIN, and trying to locate legit pin out charts

[Jand3rson]

Hard wire it if you can.

This. I'm so glad I didn't stick with that hodge-podge adapter, hardwiring it in is so much better.

[ck_taft325is]

I did not no, possible problem with adaptor, looking into now, on the phone emailing, and on skype as we speak

Hard wire it if you can.

I remember why I hated the E34 ETM tonight. x-x

You didn't by some chance replace the harmonic balancer did you? NV and Vanos trigger wheels are different and will cause a no start. Just fishing.

[416stroker]

Its dumping in to much fuel still?
After your plugs fuel fouled did you change them?

A fouled plug will give you a weak spark and a misfire. Drying them out doesn't work there don't always bounce back.

Have you tried disabling the fuel pump and priming the manifold with fuel to see if you can even get it to fire without the pump running?

Id rule out the cps because IIRC it will disable fuel and spark if its not working

[Jand3rson]

I understand that, but you need to give people more than an hour to check things out. It's 11:30 on this coast, but later everywhere else.
