My 914 still doesn’t start regularly. I turn the key and every time I heir the buzz my guess is the D-Jet fuel pumping and then it might start or nothing happens. Once it starts cranking it will start just fine. Here is a list of what I’ve done. What am I missing??? What could be wrong?
New battery Clean the connections on the battery New ends on the positive wires to the battery New ignition switch Clean and replaced connections on the starter solenoid Cleaned ground strap connections from tranny to trunk Kevan |

Are you saying that nothing happens when you turn the key?

I use to have this problem all the time and still have it today. I know for mine I was cranking mine over for to long and to many times in a row and the starter gets really hot. and the life span goes down alot. But over all if you take it out and bring it to someone to test the problem may be that is drawing to many watt's away that is what my problem was then I got a new one stuck it in and it work fine for the first few days but I screwed this one up to by just over using it.

[QUOTE] Are you saying that nothing happens when you turn the key?
Only the d-Jet pumping fuel "starter is toast ..." How could the starter be toast because when it ever decides to crank it fires right up. Anyway I think I have an extra starter. I'll put it in and see what happens. Thanks Kevan |

Could be the solenoid contacts too. I went through this too.
I put in a rebuilt starter AND a relay kit. No more problems. |

Looks nice in pictures......... Group: Members Posts: 5,271 Joined: 5-March 04 From: Colorado Member No.: 1,753 Region Association: None |
i know you guys are all saying starter, but could it be a bad fuel pump? with my 914, i used to get a buzzing sound when i turned the key, but it wouldn't consistenly start. one day, it didn't start at all. turned out it was a bad fuel pump. replaced that and i had no problems. until.............we won't get into that right now.

I was just posting something on this on Rennlist... so here is a diagram followed by photos of a relay set up for your starter.

Bandaid?... maybe...
Lots of things that aren't needed are still an improvement. IMHO any circuit in a car that draws a fair amount of current is improved when you add a relay, unless you like lots of current running through switches on your dash or in the key switch...... bonus is less voltage drop to the starter... In my case I never had a problem with that starter again... didn't have to buy another starter... If you need a new starter... buy one... then add a relay and save your 30 year old key switch. |

Cactus....it's amps, not watts......
As to starting...it's normal to hear a fuel pump buzz....no buzz no pump. Some fuel pumps will have intermittent shorts that will work once the engine is running. That's why it will start after a few cranks....it is using the residual pressure in the fuel system..... Now a starter that drwas a lot of AMPS will heat due to impedance in the wiring. This can be from bad grounds or corrosion in the postives leads..... Best to check the wiring before replacing expensive, non-returnable electrical components.... |

Andy Andy, normally I would agree with you, but the starter circuit pulls SEVERAL AMPS through a tiny wire that goes more than a couple feet up to the front of the car, then through an ordinary ignition switch. This is a bad design. There are bandaids, and there is also lack of margin in engineering design. This is a little of both. |

I will let you know when my ignition switch (or whatever it is that is going bad) craps out, but it's been 6 months now and not a single failed start.

Band-Aid. Fix the problem. Ranks right up there with people that run extra wires because something doesnt work instead of fixing the actual problem.
Yes a relay works.. I have also seen them do ZERO after being installed. No matter what happens the little yellow wire has to supply voltage to the starter solenoid. If it isnt enough then there is a issue between the ignition switch and the starter. FIX IT. I even had a reputable shop tell me they install relays with every starter purchase so people with old 911's/914's dont return with a starting problem later. They know the real issue lay's in the ignition switch but people wont pay to have it done correctly... Band-Aid. B |
