Hard starting and lean

[magik95]

I have searched and did not see anything so heres my problem. A few days ago I went out and tried to start my car and it would not start. It took like ten minutes to start. It acted like the timming was way off but its not checked it.

When it finally fired up, the narrow band a/f meter was all the way down lean and stayed there. Its still doing the same thing now, hard start and all.

Any one know what gives with this problem?

Cant tell you about the narrowband dont use it that doesnt do anything so that cant be the problem it just moves around power, ground ecu pinout.Cant see that as to the hard starting, could be battery, coolant temp sensor.

Coolant temp sensor. My temp sensor could be on the skits I guess because it does'nt go past 90. Its done that for long time. My fan runs full time though.

Read the check engine light. If the light isnt on, it maybe a fuel leak.

So found my problem. I recently drilled my syphon out 1/8" and put it back in. Well afeter a few days I had the above stated problem, hard start and running lean.

Today I pulled the fuel pump assembly back out to find the syphon assembly barely hanging on. I was dumping fuel inside the tank.

So I fixed it, made sure it was nice and tight and no more problems.

Solved!

Well I take that back!! It worked al out for about a hour, then it freking statred not to start again!
did some reading and its the damn ECT. One of hte wires broke off right at the connector. I did a log and the logger saying its -49* outside. So I know its the ECT which is making the ECU flood the damn car

Ok I got it for sure this time! Went out today and fixed the wire to the ECT. Now everything works fine. The a/f gauge is reading right ( bouncing around), no more hard starting. I checked it six times to make sure with 10 minutes embetween each start. Verified the sensor is working by logging it and reads normal now.

Issue resolved.
