Hi,
Okay, so last time I posted, I was having some issues. Well, now I have a major one, my car won't start!
Here's what happens:
I turn on the ignition, everything acts fine (no CEL, fuel pump primes, etc...) then when I try to start it it try to turnover but nothing happens. It just keeps turning and never actually starts the combustion. I've tried giving it gas to help, but to no avail.
Here's everything I've checked:
- I have spark on all 4 cylinders.
- I've got fuel pressure (fuel pump primes, and my fuel pressure gauge reads 40 psi just like it's always done in the past)
- Battery is fine (fully charged and keeps its charge, and is only 6 months old)
- Cleaned off the terminals and wires.
- Replaced the Main Relay with a brand new one.
- Replaced both the Coil and Ignitor with new ones.
- Checked the ECU (Hondata S300). I even had my local Hondata dealer inspect and test it (all came out ok)
- New MAP Sensor
- Tried another ECU for grins... no dice.
- Fuel filter, fuel pump is 6 months old, as are the wires, plugs (properly gaped), cap and rotor.
- Injectors (also 6 months old) are all getting pulse as they should be. Plugs also had fuel on them.
- Checked, double-checked and triple checked all of my grounds. They are all clean and making perfect contact.
- Timing belt is fine (timing belt jobs done back in April)
- ECU doesn't register any DTCs and no CEL or codes being thrown.
- Laptop does talk to the ECU just fine.
Now, this might be related to a previous problem. The car would every now and then throw a CEL and ECU would go into limp-mode, dump fuel and run like ass. This problem was becoming more frequent. The last time it ran, it was having that problem. I parked it in the garage and it hasn't ran since.
It's never not-started before so I am stumped.
Car is a Supercharged 98 Civic EX manual. JRSC, S300 w/ RC440, Walbro 255, 121k miles... If that helps in any way.
Please post anything that can help. I'm tired of buying new parts only to find out that they didn't fix anything. It's getting quite expensive. I need your help!
Come on guys, lay it on me.
