New 914 owner

[bobmspeedster]

Looking for some help with my "new to me" 1976 914. The car has sat for almost 20 yrs. I am trying to get all powered up. Most everything seems to work. I can not get any power to the fuel pump up front. I have removed it and got it working well on the bench. When I turn on the key I hear a relay click but not power to pump. I have remove cleaned and replaced all of the fuses/relays and can not find a problem there. Is there another place to check? Also I only get a click when I try to start(turn over) with the key. I have used a jumper and am able to turn the motor just fine, but nothing when I use the key. Any ideas or suggestions.
Thanks
Bob

If this car has sat for years I would replace all the fuel lines and the one that goes through the tunnel.If you don't you will have a BBQ and no car.Did you get the lines back on the right ports when you reinstalled the fuel pump?

what engine do you have, the 2 liter D-jet or the 1.8 L-jet. there is a hug difference in L and D jet injection systems, we need to know what you have.

The fuel line thru the tunnel may be just fine, mine are still original form 1972. this line is a hard plastic nylon material , well protected in the tunnel from damage. battery acid and mechanical damage can destroy this line, else it is likely just fine as is, the rubber hoses are a concern, todays new fuels eat up the rubber hoses unless new lined hoses are installed.

at anyrate you need to see if she starts up ok. do you have an electric diagram?? If not get one, Highly recommend you get the Haynes shop manual for the 914, it has lots of useful data, and diagrams.

could be the internal parts of the key switch have failed, new internals can be bought, so you can keep your same key. a volt meter along with the diagram will help you determine if this is the cause of your non-starting issue

A 76 is almost certain to be a D-jet 2.0 liter. (Check for the "hand grenade" with one vacuum hose and four wires hooked to it on the right side of the engine bay.)

The D-jet controls the pump by grounding one of the pins on the fuel pump relay on the relay board. That causes the relay to close, sending power to the pump. It will do this for about 1.5 seconds when the key goes from "off" to "on", to help prime the system.

The D-jet itself needs to be powered on. The "power supply relay", also on the relay board, gets closed any time the key is on, and that sends power to the D-jet ECU.

You can swap the relays for the ones on the headlight buckets to test them. You can also use contact cleaner on the sockets. And check the fuses on the relay board; one of them supplies power to the fuel pump relay.

The circuit also needs a decent ground; the ECU is grounded by the multiple ground point at the rear of the engine on one of the through-bolts on top of the engine. You may need to move some stuff to see it. Make sure the grounds are clean and tight.

You may be able to check the Visio flow-charts on Brad Anders' D-jet site; see Brad's '70 914 2.0L .
