Car Starts after 30 cranks!

[HyperFlex03]

Okay so here's the deal.....

Whenever I get out to my car in the morning, I have to crank it (tiny cranks) about 30 times till it actually fires up. No when it actually fires up, I have to give it gas just to keep her alive. After doing this about 3 - 5 more times, she finally is ready to go. Now this is only a problem when the car hasn't been running for 10 - 12 hours. I'm quite puzzled as to what the problem could be.

I'm running Nology ignition. NGK wires. I have never had a problem before. I got new spark plugs (just basic, like $6 for 4) could that have anything to do with it? I'm very confused and don't actually know why it takes such a long time to start her up. I just have to sit there and crank it little by little till it starts showing life.

HELP!

My guess is the check valve on the fuel pump is allowing the fuel to flow back in the tank. Either that or you could have a large leak somewhere in the fuel lines.

Hmmmmm.....Could be my fuel pump.....I have the 255 walboro and I can hear it wineing and what not. I have a huge built in sub box I just put over it like 3 weeks ago, when i guess it started happening. I'll check that out, but if that's not it....what could it be?

I mean am I gettin sufficient spark? or is it i'm not getting enough fuel?

A long crank usually means you have a fuel delivery problem. You could either be loosing fuel pressure when your car sits for a while or you are getting to much in and flooding it out. If you can get it to start much quicker by holding the throttle all of the way open(tells your ecu that you are flooded and need to shut off fuel) then you are getting way too much fuel in. Hope that makes some sense.

It sounds like your fuel system is losing pressure; it's supposed to stay pressurized with the engine off so that you get a quick start the next time.

Leaking can occur anywhere, the fuel pump is a possibility. Another good possibility is a leaky injector (i.e. one that sticks open). Also, I've read that the Aermotive FPR tends to bleed pressure off as well.

Let me know if this works for you: Pop the hood, look at the thermostat housing. Check all around the housing make sure every last wire is pluged in to where it is suposed to go. If one of them is unplugged then that is probably your problem. This happened to me to, and it started after a while but would try to die on me. Hope this helps and/or rids you of your problem.

Good Luck

It's most likely a fuel pressure problem. For instance, say when you change a fuel filter, you have to relieve your system of any pressure, then take the filter off/replace/etc. When you go to crank it back up, it usually takes a few seconds to crank, then runs a bit quirky for another few and then it's fine.

I'd check the fuel lines and connections to make sure they're all tight and sealed. That's the first place I would start

Also, I would maybe invest in a fuel pressure guage to be certain. If you don't want to hunt around for one, I have one I can give to you if you just pay shipping. It's used, but it works, and it's pretty accurate.

check the coolant temp sensor for the computer . the car has 2 one for the gauge and on for the ecu. If the coolant temp sensor for the ecu is out of wack, the ecu will think the engine is hot and will not supply enough fuel to start the engine . Get a Ohm meter and check the coolant temp sensor for the ecu.
