Help trouble starting for the first time

[mac2686]

Can anyone please give me some help or point me in the right direction as to what to do next with my car? First off to make things clear Its and 89 240 with a ka24de in it everything is wired up. Some other things you may want to know, I have a walbro 255 fuel pump and deustchwerks 50 ib injectors, z32 mafs, safcII, and a chipped ecu with an enthalpy tune on it apparently. When I go to turn the key I'm getting fuel and spark but it's not starting occassionally i get a boom out the exhaust but thats it. I pulled out all the spark plugs and cleaned them. I looked at the distributor timing and tryed to see if that could be the problem but didn't have any success there either. Does anyone have any ideas as to why its not starting and what I should do next? I would really apreciate someones help if any I don't know what else to do, Thanks.

Are your plugs coated with fuel?

[mac2686]

ya pretty much

Recheck your distributor timing. Plugs being coated with fuel means you have flooded it by trying to start it. Pull the fuel pump fuse and try to start it again after changing your timing.

FYI, I got occasional booms out of the exhaust when I tried to start mine for the first time, and it turns out the distributor was 180 degrees off. I'm betting thats what it is.

alright well got around to looking at the distributor and I do think that you were right about it being 180 degrees off b/c I pulled out spark plug number 1 and turned it over and got it on compression tdc with the marks on the pulley lined up then pulled off the rotor cap to look and the rotor was on number 4 cylinder so it seem pretty likely to be 180 degrees off so i pulled out the distributor with the motor set right and put it back in with the rotor at cylinder one and tried starting it. Well unfortunately it still didnt start however, it did have more booms than before though. I'm super frustrated with this thing and just wish it would start! Could it possibly just be flooded and i need to pull all the plugs and clean um off?? any advice at this point would be great i'm desperate to get this thing running and its driving me crazy.. please help, thanks!

Honestly i think you should have did the swap and started it up stock and drove it around stock a few runs then threw the aftermarket goodies on.

[mac2686]

Yeah.. I wish i would've done that too. This has been one of those deals where I've just learned a lot as I've moved along. I wish I would have planed this out more. Still looking for help, anybody have any Ideas on how to help with my last post??

Did you check to see if you have spark? you can take off the vavle cover and make sure you're not 180 degrees off. make sure at TDC(second mark on pulley) your cam lobes for piston#1 is pointing outward away from each other. if it still doesnt start then it could be something else, but usually poping(misfire) means that you're off on timing. distributor should also be facing spark plug #1. GL.

[mac2686]

yes i did check and its getting spark.... I guess i'll have to take off the valve cover to make sure i really get the motor set right for sure and then set the distributor again hopefully that will work....

[mac2686]

ITS ALIVE!!!!! i cant beleive it i FINALLY got my car running after sooo effin long!!! I took off the valve cover to get the motor set right for sure, whats wierd is when it is set the marks on my pulley dont line up but the #1 cylinder cams are pointed out like the write up says and the piston is also at the top of the stroke so i think maybe the pulley came off my old sohc motor i guess i dunno... but after that put in the distributor with the rotor on 1 and got everything all together and when my dad got home we were messing with it and got it going on its own first with starter fluid and the fuel pump fuse out. So we learned that when we put it back in it gets to much soo... i guess the next thing is a fpr to get rid of all the fuel pressure does any one have any recommendations on what i should get?? I was looking at this one from megan racing http://enjukuracing.com/megan-...2_136 but i don't know if thats exactly what i need to get. I was always under the impression that i wasn't gonna need a fpr since i've got a tuned ecu and an safcII, I was thinking i'd be able to adjust it thru the safc. Anyways somebody who knows more than i do let me know what ya think.... im feeling the megan racing fpr but just not sure.

Good to hear that it's running. My friend have the megan one and it works fine. i preferre the aeromotive one since a lot of people w/ high hp are doing good with it. i personally own a nismo type B w/ adaptor, but if i knew about the aeromotive one i would of got it.

The thing w/ stock fpr is that if you upgrade to bigger fuel pump then, it wouldnt be able to handle the flow and may crapp out on you. It happened to me once while on the way back from dyno and since then i recommend anyone turboin their 240 to buy aftermarket fpr because i dont want anyone to be stuck on the freeway like me, holding up traffic.

Remember the purpose of fuel pump is to makes sure you have the right amount of fuel pressure going through hardline to the injector and back to fuel tank. while fpr regulates and maintain the pressure thats going into the injectors. the injectors controls how much is thrown (at certain duty cycle) into your motor. There's more to it but you get the idea.

hope this helpGL.

I've been messing around with my car a little today and have some thoughts. First thing is my car just turns over with the fp fuse in but when i take it out it will start up and run for a little bit and then shut off obviously b/c it burnt up all the fuel i guess?? So i wondered what would happen if i put the fuse back in turn the car in the on position and let it prime then take the fuse back out and try starting .. and when i did it briefly started, which makes me think I have a leaky injector or something. However, the injectors are new. Could I have damaged an oring on the install and this be the cause of some fuel getting in there?? also is there any way i could use my safcII to adjust the fuel and make it start?? I'm just hesitant about the problem being the fpr and dont wanna rule it out just yet. opinions please also I'm on aim right now my screen name is mac2686 please message me if you have suggestions or questions thanks, Matt
