Anybody else feel like all they ever do is ask for help fixing their car? Anyway, please help - I have no backup car this week, ice skating lessons for a 4 year old, science fair for a 4th grader and a car that is acting up!! Here's the scenario-
Yesterday afternoon, car cold, cranks over fine, no start. Try again, starts fine, idles a little low. Drive 30 minutes, stop for 5, try to start, cranks fine, won't start. try again, does start Drive 5 minutes, stop, - cranks, no start, tryagain, no start, 3rd try does sttart this morning, first start of the day, starts ok, idle low, i check under the hood, there is a little dampness (gas) near fuel injector #1, nothing else. started ok though, so i go about my day, checking every stop for leaking fuel, see none. this afternoon, repeat of yesterday. this time though, on my last stop, it took 4 trys and prayers from my kids to get it running. wouldn't bumps start either. also, this afternoon i notice that at about 2400-3200 the engine is stumbling a little, never done this before. i'm thinking its not gettting fuel. - or maybe too much fuel maybe the injector is going? i did just replace the pcv valve? i heard the fuel pump prime so i don't think that's it. like i said, i have very little time today and am hoping to start looking in the right place - my thoughts are pull & check plugs check for spark but as for checking the injectors, never done it? maybe timing? your thoughts? |

Wild guess, does it still have points?

The computer gets a reading from the temp sender and adjusts the fuel/air mixture to compensate for a warm or cold motor.
My 2.0 would die at the stop sign once it warmed up. Sometimes I would have to push it to the side and wait untill it cooled down before it would start. It took me 2 weeks of diagnossis to figure it out! I thought all FI 914's had one?? Maybe someone else would know for sure. Jeff |

Race: It has a CHT, and there is a test for that. The CHT is a resistor that changes it's value with the temp of the head.
Check the Points to see if they open and close (pop of the dist cap with the car in 3rd gear and move it till the lobe on the dist shaft points at the contact piece of the points). You should have about .017" about the thickness of a match book cover. I don't run points because they are a problem. :PERMAGRIN: Joe |

there is a little dampness (gas) near fuel injector #1 please do yourself and me a favor and fix that ... a burning 914 is not something you want to see for yourself ... (IMG:style_emoticons/default/sad.gif) Andy |

Race: Thats a little too lean. V8 Sean lives down near you, maybe he will chime in.
Some good info here http://members.rennlist.com/pbanders/ Paul Brad Anders is Thee D-Jet Guru. Sorry I don't do links. :PERMAGRIN: Joe |

yeah too lean was my thought. been on paul's sight. hafta admit - this is hurting my head, its a far cry from my rochester ... wonder if that'd fit under the hood (IMG:style_emoticons/default/smile.gif)
about that leaky injectoor - i lied its #2 - and its barely there, but seems to backup from the little rubber hose that goes from the fuel rail (is that right) to the injector itself. is there some kind of sealant i can put there? and why would it do that? really don't want to blow up my car. |

It could be something as simple as low fuel pressure or a dirty fuel filter.
It sounds like with the multiple starting that your system is trying to build pressure. |

You can just replace the hose from the injector rail to the injector. Its like $.10/inch at the local stores. I think 5/16" works, but check first. Also, get the smooth hose clamps without the holes for the gear (these are for fuel and the others are less safe).
As for intermittent stuff: -the CHT can have an intermittant open causing a rich running condition (IIRC) - Fuel pressure intermittent could be the filter as stated above and could cause the problem. - Points in my experience are not that big of a deal to do, but take some learning. Just check 'em and go from there. They are not all that hard to adjust in a /4. (Just consolidating info) |

(IMG:style_emoticons/default/agree.gif) I had a somewhat similar problem where it frequently took two tries to get it to fire. Turned out the fuel pump was going bad. It finally failed completely. Good luck. |

(IMG:style_emoticons/default/agree.gif) when was the last time you checked your fuel filter? (IMG:style_emoticons/default/idea.gif) Andy |

Good Luck Race: I have a Love Haet relationship with D-Jet. I have a souped up 2056 that is cammed and ported and makes great power. Linda's D-Jet was worked on for 18 months by 3 shops and myself, before she finaly desided to put carbs on it.
There some good pictures of the sensor lay-out in my blog. :PERMAGRIN: Joe |
