Starting Issue

[The Banks]

After being driven, warmed up, and then parked for about 20 minutes my car took about an extra 2-3 seconds to crank, it just about started then died. This is the first time it's actually failed to start on the first crank, but recently, I have noticed that every now and then it will take an extra 2-3 seconds to crank before starting. On the second and each successive crank it starts right up, however, there may be a rough idle sometimes after starting. I replaced my wireset, plugs, and coil pack a year and a half ago which was probably about 10,000 miles ago. I have a 2000 with ~75,000 miles. I was thinking of changing my spark plugs for the hell of it this weekend and putting in TR55's again. In reference to a similar thread, apparently a clogged IAC, a bad CPS, or even a bad fuel pump can cause a problem like this. What do you guys think?

Re: Starting Issue

Ah ha, forgot to mention I replaced the fuel filter when I replaced the wireset, coilpack, and plugs. You bring up a good point though. Could something like this be a result of gas quality? I've been putting in regular 87 Costco gas for about the past year.

Re: Starting Issue

i doubt its bad gas.. the only other thing i can think of is leaky injectors are flooding the engine out, or a bad IAC

if you have a cable throttle body, try flooring it when starting, if it starts right up with no problems it is probably the injectors, or a dirty IAC

Re: Starting Issue

How's your gas mileage been? Been running rich lately, or even smelling gas on startup? Hard warm startups are a symptom of a bad fuel pressure regulator. Assuming you haven't replaced it, the diaphragm in the fpr has probably worn away and is allowing fuel to be pulled through the vacuum line into the intake.

Pull the vacuum line at the back of the fpr (the one that runs from it to the back of the upper intake manifold) and see if any fuel comes out. If there is any fuel in the line, then you need a new fpr. If not, time to start looking around at other options.
