m20 woes

[Edev]

I posted this in the m20 section, but I'm not too sure how many people look in there.


I came home two nights ago, then tried to start it the following morning but it wouldn't start. It would just keep cranking and cranking. I've replaced the following with known good parts: m20 afm, spark plug wires, ignition coil, and distributor cap and rotor. It's getting fuel. Timing belt is 1yr 8 months old. What the eff. Any ideas?

When I crank it and I leave the oil cap open, I can see the cam doing it's business..as in, it's turning and turning.

Fuel pressure regulator..even though it's getting fuel? I know this because I pulled the fuel line going into the injectors and fuel is coming out when cranking for a second or two.

Any ideas? I kinda need it to get to work and all that good jazz.

I don't have the tools to pull a plug.

When I start it, well try to start it, it reaks of fuel.

sounds like no spary like we said, your rear toolkit has the tools to pull a plug...


i have a plug socket somewhere, ill look for it

My rear tool kit doesn't have it. I have like no tools from there.

very rare that you wont be able to get spark AFTER the plug. Pop a plug wire off, put a flat head screw driver in the end (dont wreck the metal clip inside the boot) and have someone turn the car over while you hold the screwdriver, touch the exposed metal part of the driver to something metal on the car (strut mount bolts). if you can see a spark going between the driver and the metal you know youre getting spark from the coil etc. this is of course if you cant locate something to pull the plug.

has anyone messed with the ecu recently?

Right on Jeff, thanks. I'll be doing that when my dad gets home, as I'm the only one home as of right now.

To my knowledge, no one has messed with my ecu. It crossed my mind that it could possibly have gone bad over night, but I don't have access to someone with the same (or similar) ecu as I do.

I checked the cps in my car. I traced the wire down to where it bolts up. The wire was very loose and had what looked like black electrical tape on it. I've got a new(er) one that I'm going to install. The problem is, the cps that's currently on the car is reallllly putting up a fight to take it off.

just say eff it and swap that bitch hahaha

Haha, I'd like to but I don't have enough money.

Also, the CPS was not the issue as I just replaced it.

are you sure? what about the coil find out it you are getting spark

[Edev]

Yeah, because I just swapped it out with a known working cps. How would I go about seeing if thr coil has spark? I've used three different ones. 1st one was mine. And the 2nd and 3rd were from previous working cars (jasons and trevers).

Well if you test the wires for spark like mentioned above you should see if your'e getting spark.

Or if you're depressed and really don't think you have spark you can just touch it with your hand like I did. Then when you get shocked (like I did) you'll be happy that it's working and in mass pain all at once. It's better if you have a friend there to laugh at you.

Haha. That's what my dad said; touch it and get shocked lol.

I'd like to go and try now, but my car is parked outside and it's sprinkling/raining.

even better!

[Edev]

even better!

Lol. If anyone has a complete motor swap available, I'll do payments! Haha jk. I'm hoping to try a few more things tonight to see if the problem continues.

Mine was not starting a few months ago. I put in new plugs and it started right up.

That's my next plan of attack. Pull the current plugs and let the cylinders dry out a little bit (possible gas, aka flooding) and throw some new ones in. If that doesn't help, I'll be looking for a 179 ecu. Does your parts car have one? If it does, I'd like to test it out in mine, to see if that makes a difference. And if it does, I'll buy it from ya.
