I have a 2000 CTR B16B from HMO all stock motor (walbro 255 fuel pump, k&n air filter, custom exhaust with apexi ws2 muffler) in a 1997 civic dx frame (98-00 interior).
The build up:
a few days ago (lets call it day 1) i was driving around in the canyons for a good 3-4 hours, a couple times i red lined my engine which has never been a problem before, then made my way home. On the way home my friend blew his h22 because he decided to drive with no oil. So the next day (day 2) this certain friend asks me to take a look at his h22, i go over to his place, 10 miles away, and get let into his parking garage area, he "feel asleep" and i got stuck in his garage area for an hour, trolling back and forth between the 2 gates hoping someone will come in or out. I essentially idled my engine for an hour... Then on the morning of day 3 i jumped on the freeway to go get exhaust work done....
The problem:
I have made it about 5 miles on the freeway and my car starts to jerk a little bit then stops. Then it starts to jerk worse and worse, it feels like it is running limp or with a misfire. So I pull over onto the streets to take a look, everything seems to be fine and the tugging stopped while idled, then it suddenly dies while im looking at the engine bay! I turn it over and it barely starts and im trying to figure out what is wrong. I got home and put a new coil in the dizzy and it doesnt help so i put the old one back in and go to turn the car over, nothing. The car wont start now, just a single loud thud or click, but ive had this problem before from a bad ground, so right away i replace all my power cables and battery/vc and tranny grounds with 1 gauge quality wire. Now the car cranks strong but still wont start, check a few things, no spark now so i replace the entire dizzy. Then before trying to start again i check cam timing, all good but cylinder 3 is totally flooded with gas, so i let it dry out for a while. Go to start car and it barely starts and i have to hold down the gas pedal for that and then it runs like crap and dies if i dont give it gas. I am now upset. Called a couple people and looked online...
What i tried:
~I checked the dizzy/wires/plugs and i am getting nice white spark on all 4 plugs.
~I looked at the spark plugs and cylinders 1, 2, 4 are all black while cylinder 3 is clean and new.
~stethoscope on the fuel injectors, pretty sure i heard clicking.
~took fuel rail off and cranked, injectors 2 and 3 popped off rail gas poured out.
~checked fuses 12, 13, 15, 24, 31 and back up fuse in engine bay. all fine.
~fuel pump primes but also exessive white smoke and fuel smell when idling car, note that there is some seafoam in the fuel tank .
~cam timing looks perfect, as does ignition timing (checked with light).
~car will not idle unless i take out MAP sensor then it has a rough idle with heavy fuel smell. white smoke from tail pipe (see previous point).
~no CEL until i unplug map and then do jumper pin, only CEL then is #3 (map sensor?)
**should i mention that even with the ecu fuse out (7.5 in engine bay) the car runs exactly the same?
The car does not feel drivable even though i could take it around the block without more problems. Rough idle (none with map sensor in), drives like there are misfires, sounds like there is no exhaust (there is), lots of white smoke from tail pipe, no CEL.
Ive been at this car for 2 days trying to get my only transportation running again. Right now I am considering a few things for which I already have the parts, such as:
~changing main relay (i have another 97 civic i can take relay off to test)
~using stock fuel pump (i still have it, using walbro 255 right now)
Outside of that, maybe its a bad MAP sensor or TPS?
Any input would be extremely helpful! I am ready and willing to learn something here... Its driving me insane!
