takes a while to start my car

I have a 94z. My car is taking a long time to start. This problem started about a month ago and seems to be getting worse. Sometimes it will start right off, but other times it will take up to 5 seconds to fire. It cranks constant acting like it isn't going to start and then all of a sudden it fires up like a champ. I don't car too much about the long starts. But the fear of it getting worse and the possibility of getting stranded concern me. It is also kinda emberrassing. I don't have a clue what this could be. If anyone has any ideas on what this could be please help. Thaks alot

Re: takes a while to start my car

ah poop that's what I was afraid of. I have driven through a little bit of water, but I haven't been crossing rivers in it. (I use bridges). The performance has been fine lately. Maybe I should go flog it and see if anything happens.

Re: takes a while to start my car

Re: takes a while to start my car

Usually long cranking times come from fuel problems. Either the fuel is leaking into the intake or draining back toward the tank. These problems can be see with fuel pressure gage after the engine is shut down. If the regulator is the problem, the vac line connected to it will be wet with fuel. If the check ball in the fuel pump is the problem, the car will start easier when the power is cycled on for 2 seconds and off several times before actually cranking the engine.

If the injectors are leaking causing puddling in the intake, the power cycling will not help but holding the throttle wide open when cranking it may.

Re: takes a while to start my car

i had the same problem. my injectors were leaking. it would start fine in the mornings after the fuel leaked out of my fuel line or if i would crank it back up before it would get flooded but if i let it sit there for a few minutes it would take 2-5 seconds to start.

Re: takes a while to start my car

I had a similar problem with a '95 TA. If I had been driving it recently it would fire right up, but if it sat for a couple hours or longer it would crank for a while. It got worse and worse until sometimes I would have to try for 5 minutes before it started. The dealership said it was the Opti and that I had a leaking Water Pump so I changed them both but the problem never went away. The car was totalled so I never found out what the problem was and I still have no clue but I would love to know if anyone does. Good luck.

Re: takes a while to start my car

When I put my 160 degree thermostat in my car, the silencer tube hit the connector on the coolant temp sensor and damaged it. After that, my car would not start right, it wouldnt fire immediately it would just turn over. I figured out it was the sensor after i fixed the connector, the problem went away completely. It would only throw a code sometimes, i think it was due to the fact that the connector was just BARELY keeping contact.

Re: takes a while to start my car

I've dealt with the exact same thing for 2 years now. Here's the links to the threads I made to see if I could find anything out. The first thread pretty much answers it. I still haven't fixed it (notice it was '03 when I posted those) but I think I might ASAP once May gets here. Good luck man.

PS - If it WAS the opti you'd probably have other problems, too. Like stumbling up top (mine did), rough idle sometimes, and worse gas mileage (I think). I'm almost 90% certain it's fuel related.

Re: takes a while to start my car

I am going to put a new in-line fuel filter on and spray some starting fluid down the throttle body, and mess around with my car a little bit before buying a fuel pump, which looks like the problem. With some more testing I will hopefully track the problem down. If it is the fuel pump is this the one I need?

I have spent way too much time and money on keeping my car maintained lately. This is getting frustrating. My car is a money pit.

Thanks for all of the help.

Re: takes a while to start my car

Go buy a fuel pressure gauge for $40 and check the fuel pressure.

I'll bet your porblem is the fuel pump.

Re: takes a while to start my car

I'm having a very similar problem. I ended up yanking my Optispark out and found that a series of bolts were loosened on the opti/timing cover (which I tightened upon reinstallation). Anyway, I found that when i spun the opti driveshaft, I heard a dragging noise in the optispark itself. I checked fuel pressure and its right at 40lbs so that seems OK.
