I just tried to start my newly rebuilt engine and nothing. It turns over and has fuel and spark, but it won't catch and start. I'm so frustrated, what could be the problem?

Any help is appreciated.

Maybe she's flooded?

momar

It could be, but I just sent the injectors out to RC Engineering to hve them cleaned. The spark plugs are new too and I set the CAS correctly.

Did you prime the fuel system? Theres a yellow jumper near the airbox. Jump that and turn the key to on. This should get any air out of the fuel system but I dought its your problem.

you put your fuses back in? i know i forgot to do that one time, and i was cranking for damn 25 mins before i saw them on the floor.

momar

Yeah, I primed it and can see the fuel mist out of the plug holes. All the fuses are in also.

I though I read somewhere that rebuilt engines have low compression until they are run for a while. Is there anything to raise it if thats the problem?

Check your ignition timing.

Marc, i think you set your CAS internally correctly (notches), but the IGNIGTION (timiing marks) must be off.

momar

andre, you mean the marks on the pulley itself or just the timing.

Momar...

I amassuming this is the first engine you have done.

The reason i say this is because I struggled with this as well the first engine I did.

Just make tripple sure that the timing is right, the injectors are primes and put a battery charger on it.

It will take time, but it will behave like the worst flood start you have ever had to deal with on its first startup.

It took 2 hours for me tpo start the first engine I did because i didnt realize it was a flood start condition I was in.

I know its not flooded, but thats what it was.

Just crank the heck out of it.

If you can roll start it do so, but make TRIPE SURE that you have all of everything connected.

Double check the connections you made last.

Air hoses, vaccum lines and of course the mass airflow sensor connection!

All the final intake related connections are the easiest to forget somthing on.

If all is right, it just takes time to start it.
follow flood start point procedure.

Thanks everyone, I knew that it may be hard to start, but didn't know it would be this hard. I'll just keep trying to do it then.

Don't burn up your starter!

Hey...

RXTASY1

That chick in your avatar would be about 3.5 feet high if she stood up!

A bit off scale there!

momar

Is it possible that the gas has gone bad, the car has been sitting for around four months.

If the gas did go bad, would would filling it up with fresh gas solve my problem?

Sniper_X

Only one way to tell.
DO it.

And no, its probably not bad.

Roy James

um.. i dont think the gas has gone bad.. i have gotten cars in the Junk Yard fired up a few times with the junk in thier tanks... and who knows how long its been in there, . But, as the saying goes, it cant hurt to try.

Pour some atf in those pl;ugholes and that biyoatch will fire right up. We just started another rebuild tonight...friend's 87 t2. I wait until nighttime, so the neighbors wont bitch about the smokeshow

Yeah, hell of a smokeshow you get with the ATF trick, automatic tranny fluid, for all you retards out there. Just put some ATF in it, and like the ****** said, the biyatch will start right up. Expect lots of smoke for about 10 minutes or more.

Sniper_X

The prose of your writing style doth romance me so.

momar

Update...

IT STARTED UP!!!

Oh man , I'm so freaking happy. It smoked like a bitch, actually hasn't stopped smoking yet.

The only thing is that it won't hold an idle, I'm off to search, but if you guys have any help is more than welcome .

Thanks everyone for the help.

A frech low compression rebuild wont hold a good idle for a few hundred miles, or at least a day's worth of idling int eh driveway, form my experience of 10+ now. I generally use the idle stop screw to raise it up to around 1500 and let it sit there and run for a long time while Im making final checks and watching for leaks, variation in temp adn oil pressure etc. and cleaning up, installing the hood, etc. Then start driving it around. Every time you shut it down it will try to flood, so youll need a flood switch for the first few weeks. After about 1500-2000 miles it really gets a lot stronger, and quits flooding. After the first 2 days or so, you should be able to adjust and get the idle down around 900 and hold it fairly well, but be advised it is not strong enough to hold a realy rock solid idle for a few hundred miles at least.

no hypntyz7!! you have to drive it around without the hood on first.. before you install it.. Because it's fun just up and down the street at least haha

my 3 rebuilds have had NO flooding problems at all... Once all electronics were properly plugged in (took very long time to figure out my problem) all 3 rebuilds fired right up perfectly... and I managed to get a decent 1k idle from them...as you said, you can just set the idle real high so it will idle at 1500ish ..
Keep an eye on compression .. Daily I would suggest
