I had a fuel pump put in 6 weeks ago after a failure, since around that time I have had a hard time starting. It will crank and crank, after a little bit it will start to catch and die, then finally start. I'm not sure if it started exactly when the fuel pump was replaced, if not it was soon after.
I am following the advice in the "excessive cranking" article, I am renting a fuel pressure tool from autozone tomorrow.
The truck runs fine otherwise. It does not have much power, but it never did. It is a bucket truck and carries alot of weight.
The longer it has been sitting the longer it takes to start up. It seems to crank fine.
Once when I was cranking it longer then normal due to frustration it threw up codes p0171 and p0174 but just that one time.
I will post again after I get the fuel pressure results.
I have been riding around with the doghouse off, I have not smelled any leaking gas and have not found any vacuum leaks. There don't seem to be many vacuum hoses. I guess there is vacuum under the upper manifold. Im hoping it isnt the fuel pressure regulator, looks like a pain to replace.
Great site, thanks for all the articles. I've learned alot from reading the questions also.
have the same problem?
