The story of how it got to this point will be in italics for those who can't be bothered w/ reading a long post.

Well this problem started in January... I got the car inspected and it passed, wee. Then I drove around a real fun road here for half an hour and had a good time.


Then I went home.



That night it was pretty cold out. I started the car but it wouldn't idle. This had happened a lot before, I jus thad to keep it alive with the gas pedal for 10-15 seconds and then it would idle on it's own. Except it never did, for 2-3 minutes I did this then turned it off.

I tried again to no avail. So I took the Honda out for the night since I was already late.



So I tried this a few more times.... And at some point the car just wouldn't start. I however was convinced it wasn't flooded, didn't see why it would be (stupid.... I know). Or well, I tried unflooding it by taking out the EFI fuse and that didn't work, so I was thinking: "It can't be flooded THIS bad."



So over time I have to leave and come back from college... So I've had very few times I could be here and work on it. Since the problem arose I've been home maybe 10 days max, over half of those days were too rainy to work on the car any.



But in the time I've tried to get my car to run.... I've tried looking at suggestions...

Spark: I definitely have spark on all 4 plugs, checked them, even got shocked by one.

Fuel: Well.... When trying to start it a few times I've been able to smell fuel so... I'd have to assume I'm getting fuel....

So...... Flooded! Since I smell fuel and it won't start, just turn over... Must be flooded.

So the other day I took the plugs out and tried spraying gas out.... problem... Engine would barely turn over. Battery was insanely weak.

So I wanted to get a new battery after I went on a trip to the mountains with some friends....

I get back and our neighbor has a charger so we were going to use it... But Dad is all gung ho about starting it from a roll so we tried this today instead since the same neighbor could help with this.

So far..... The car would start... We saw tons of smoke the first time it started, and after that not much when we tried. The problem is the car starts.... But then won't stay on. We can try giving gas and nothing happens. It just dies after a moment. I tried, my dad tried, and the neighbor tried. So we've had about 5 tries total... And it just won't stay on.


The most progress we had was when the neighbor tried it, he said the car would idle at 2500RPMs for a moment.... But he couldn't really get it to do anything else.

So right now we're charging the battery to try some more since it's barely doing anything.... But other than that..................any ideas?

could be a vaccuum leak or a bad AFM. With a bad vacuum leak, it will start and run like crap for a few seconds then stall out.

If it is turning over really easy like it has no compression, it is probably flooded. Try doing the full unflooding procedure a few times: take out lower spark plugs, turn over 10+ seconds with egi fuse pulled and at WOT, put oil (2 stroke works best) into spark plug holes, and try to start with egi fuse in with foot off the gas pedal

A bad AFM will allow the vehicle to fire up but it will not continue to run. Try using a jumper wire on the yellow two pin connector by the passenger strut tower with the key in the on position and listen to see if the fp is running.

I don't think it's a vacuum leak because it ran fine then just messed up that one day.

And I did do the unflooding procedure. Then proceeded to try to start it from a roll today rather than doing it again after charging the battery.

And fp.......... Do you mean fuel pump?

MaxDuo

Oh. And a little more....

When I had the problem before where it would start up and not idle.... A day or so later it also was hard to keep running even with gas. I could keep it going if I was revving it up a little over and over. But if I tried to hold it in place it would seem like the pedal suddenly got a bit harder to press and seemed to lower the RPMs some w/o more gas given. It also felt like it got a little harder a few seconds after starting just blipping the throttle a little.

fp=fuel pump. The afm is just one part of the efi system on our vehicles. I a problem closely resembling the one that you are having. Are you sure that the clicking noise was not coming from the fuel injector box that is right behind the passenger headlight?

MaxDuo

Never mentioned a clicking. Are you refering to the fuel pump clicking on? I wasn't really questioning it since when I tried to start it one time before I smelled gas.

I guess it could be the afm, I know what it is hehe.. I had a bad vac leak a while back and was checking out the afm when I realized where the vac leak was. So a bad afm could cause the car to die off no matter even if I press the gas down, as in it'd not react to the gas pedal at all? Because that's how things are being... It'd start when rolling but I couldn't get it on even w/ gas. When I had trouble with the car staying on a while back the gas pedal would suddenly become rather worthless seeming in the effort.


Anyway, after the battery charger claimed it had finished charging the battery tonight... I tried to start the car and it did nothing. Didn't turn over. So I was thinking: How'd the starter die? Then wondered if maybe it was the battery still somehow... So I tried to open the windows.... barely moved. And the light in the car was pretty dim. Battery must be screwed up somehow I guess......

MaxDuo

Well, I just went through the painful process of putting my Honda's battery in the RX7 (painful because the Honda's connector's were put on in a way that no tool seemed able to loosen... and were really tight.....).


Anyway, put it in the T2 and she started right up. Beautiful sound of the engine has returned. Was perfectly fine, jus tlike the car was running as normal.


But then it revved to about 2k RPMs... Then died. So I tried again, revved to 2k, and died. The first time I was blipping the throttle a little, bounce it a little over 2k but when it lowered back down it just dropped w/o responding. The 2nd time I started it, it again revved to 2k and died, it showed no response to the gas pedal at all.

So I know this could be a vacuum leak... Or the afm.... From when this happened in the past and it was a vac leak and people suggested the afm or a vac leak... I don't see how it could be a vac leak right now though. I drove the car for around 40 minutes the day before it's trouble showed up and she ran a strong as ever, no problems at all. Then suddenly this happened that night followed by the flooding that I didn't believe actually happened heh.

So........ Any other suggestions? How can I test the afm too? I remember seeing something about it in the past, someone sent me a screencap from the FSM.... I think it was from that at least. Just want to see what else it could be, I'd hate to go through the trouble of getting a new afm since those cost an arm and a leg new and I dunno how many people sell theirs.... I know people get new ECU's and don't need them, but I'm not the only one needing to buy a new one so.... if it is that... Annoying.
