B20 vtec turbo EG, crank but won't start. *FIXED*VIDEO ADDED

By B20vtec-turbo
- Fri Dec 24, 2010 6:56 am #229617 As the title say's, I have a 94 hatch with a b20 vtec turbo, I'm tired of throwing parts at it and ready for some help....

I can walk outside right now and crank the car, it will start and run for about 2 seconds, then die....NO CEL'S....Checked fuses, I can hear the fuel pump coming on and all of my plugs have a spark.

I've read alot of other forums with people having this problem but no real answers to why it doing this. Some say its the timing, some say its the main relay, others say its the dizzy.

I don't think it's the timing because the 2 seconds it IS running it sounds good.
If it were the main relay, it wouldn't start at all, right?
if it were the dizzy, I wouldn't have spark, right?


Please any help would be appreciated, I'm ready to drive this thing!!!
Here are some photo's to look at while you think!

you say you hear the pump priming than it will start maybe something is causeing it to not get enough fuel to stay running

is this a new problem or has it been doing this for awhile

Well, this setup used to be in my crx, I just done the swap back in Sep, back then I was getting iac and iat codes, I thought it was my computer so I bought a new p28 and got a the hondata s300, then it pulled the same codes, so I ran through the harness and found I had some wires crossed. I just have a base tune right now, but it is supposed to run/idle with it. A few days ago, the car would run, but very rough. It wouldn't idle at all. Then I saw my Map was readying like 983. and then during a datalog I saw the map sensor code flash on then back off, so I bought a new map sensor and now it reads perfect, but it still won't run. This motor hasn't ran right, or been driven since the swap.


ALSO, I smell gas when trying to start it, not 100%, but I don't have the feeling its gas...

- Fri Dec 24, 2010 12:22 pm #229645 It would have to be a fuel problem though because if it starts that means spark is good, So maybe a new fuel pump or bigger injectors? Not to sure but that's my two sense.

- Fri Dec 24, 2010 3:09 pm #229657 your TPS sensor plugged in? or correct plug?

check your grounds too this happend in my friends all trac celica.

I have RC 550cc injectors and I can smell gas while trying to start it. Although I won't opt it out, I just don't think it's a fuel problem. Also I have checked every ground and fuse, everything looks good.

Thanks for the help, and keep it coming!

TPS is plugged in and is the right plug. I can open SManager and start to data log, without starting the car and press the gas and watch the TPS Sensor gain percentage.

Thanks for the help and lets keep it coming, I'm really wanting to drive this car, I feel like its going to be something stupid, I've doubled check everything twice, I'm not even pulling a cel.....??

- Fri Dec 24, 2010 8:27 pm #229707 Come on people! Help me get this thing going! Some told me they think its one of the resistors in my dizzy. So, how can I test that? I've looked all over the internet for a diagram explaining what the wire on it go to, and how many ohm's each one should be. But no luck....

Yeah I wired in the resistor box. I've went through it 10 times maybe thinking I wired it wrong, but I didn't.

As far as fuel pressure, I guess it COULD be that, but like I said, I can hear the pump priming under the hood (I have 2 pumps, the one under the hood is tied directly into the one in the tank, so if the one in the tank is bad, the one under the hood wouldn't be working either)

This is all good advice, Keep them coming! I've been through everything 10 times and I'm ready for the fix. I'd rather not throw anymore parts at it, I rather find ways to test for problems.


I have not CEL's on.

So, if I could find a way to test the ohm's on the dizzy resistors, I would, but I can't find a diagram for the dizzy itself to know which wires go to which resistors. I have the dizzy with 2 plugs, if anyone wants to help me look.
