914 won't start, injectors not firing fuel.

[surfdogskier]

Hey guys, new to this forum. I have spent some time on PelicanParts forum. Dave is great there but I really like the knowledge here.

I could use a little help.

I have a 72 914 1.7 that hasn't been started in while. When I got it, she was a mess. I have since installed new injectors (old ones leaked), all new vacuum houses, fuel pump and filter, plugs, wires, distributor plate.

When I try to start her, she just turns over. I know she is getting gas through the lines. I hear the pump working when the key is turned on. I ran gas through the lines before installing the new injectors and gas poured out. Haven't checked the psi but it looks good and strong.

I am getting spark. She will start with starting fluid and then die.


I pulled the driver side injectors just because they were easier to get too. Neither injector fired out any gas. I'm sure the passenger side is doing same thing but I will check. Like I mentioned, I ran some gas through the lines with the injectors off after I installed a new fuel filter to get any junk out of the lines. They should not be clogged. They are brand new injectors.

I will try and locate the ground for the injectors. There were so many loose wires and loose vacuum hoses, many going to the wrong places, on my car. I think I have them all sorted out now.

I am getting some voltage to the injectors but very little. From what I read, I need to check the amperage next.

My issue may be the grounds. It was hard to trace the grounds but I think I found where the were pinned directly under my air filter unit on the engine itself. My engine is very oily and dirty. I want to get it degreased up when I get here running. Would I be better off installing a new ground point and connecting it straight to the negative battery lead? That way I can remove most of the grounds I have and put them in a better and cleaner area.

Also, what are all the connectors for on the ignition coil? My coil is really shaky. The clamp is connected to the motor well but very loose around the ignition coil. If those are ground points on the coil, they are not getting a good contact at all.

Any help would be greatly appreciated.

remove injection, deposit in dumpster, purchase dual 40's and install them

Carbs are for absolute morons....who cannot figure out a simple 23 wire system with five sensors. Being pointy and funny but its an absolute fact

Carbs are fantastic! I have 2 of them. One I use for propping the garage door open and the other is a wheel chock.

With D-jet...no injectors firing at all is either one of three things:

1. No power to or from the main fuel injection system relay.
2. An unplugged, bad plug or broken plug at the three wire connector plug on the distributor. That connects to the injection triggering points.
3. A disconnected or corroded ground bundle on the case centerline under the air intake syatem.

The injectors fire in pairs. Each pair has a trigger wire from the ECU that is fired from the three pin plug on the distributor. Each injector has a ground wire. Those pair up and all connect at one lug on the case centerline. A diaconnection or corroded terminal at,any of these will prevent any and all injection.

Stop and clean all component plugs and use some of this on all of them. One liquid eats and removes all oxidation and the other is a kick ass connectivity electrolyte.

Worth every penny.
