Oh my gosh!!!! She is back to doing this same thing all over again. I finally got her running . She ran fine one evening, parked her. Next day she would not start. No power to the injectors. I got spark. I got gas in the lines. Fuel pump works like it should. I took the distributor out and cleaned the trigger points to see if that would help. All wires are connected. MPS connected. All vacuum lines connected. I bought a noid light set up and they are definitely not getting power.
What else could it be? Something on the relay board? Bad relay? This car is driving me insane. I am about to go duel carbs and drop this piece of **** fuel injection if I can't get this thing running. |

How do you know you are not getting power the the injectors? This is not a static signal. Pull one and point it into a jar and crank it. Make sure you are getting something or not. Are you sure you have fuel pressure?

I have never used a noid light so I don't know how that would work on an injector circuit. I am still suspicious about this being an injector firing issue. Did you try as I suggested? Remove a pair of injectors so they can be inserted in jars. Try starting several times to see if you are getting fuel. Are you sure you have fuel pressure? I am a firm believer in the KISS principle. Keep it simple and make sure all the basics are covered before jumping into more complicated causes |

I am a firm believer in the KISS principle. Keep it simple and make sure all the basics are covered before jumping into more complicated causes I did not pull the injectors since I had a noid light which showed no power. All 4 plugs have fire so they are obviously not get any gas being supplied by the injectors. Again, to many issues with fuel injection. I am going to make it simple. I am converting to carbs which I have already bought along with new fuel pump and distributor. I am so looking forward to ripping this stuff out and moving on. Anyone interested in a fuel injection set up, I will be selling it all. |
